Session 1: Marmoset Availability

JON LEVINE, Wisconsin National Primate Research Center | Video | Presentation

Marmoset monkeys have received heightened attention by the biomedical research community as non-human primate models for the study of human diseases.  The increase in demand for marmoset monkeys has been driven in part by its recognition as practical non-human primate subjects that can more closely recapitulate the physiology and pathophysiology of humans, thereby strengthening the translational value of research studies. The advent of new genomic editing techniques and other groundbreaking technologies has also raised the profile of marmoset monkeys as subjects for development of non-human primate models of inherited or acquired human diseases. There has been little consideration, however, of a national strategy to expand and enrich the marmoset colonies available for research.  Such deliberations are now underway at the NIH and among professional communities, and will be the subject of this introductory discussion.

Extraordinary aspects of the common marmoset’s life.

In the Northeast region of Brazil, we use to say that is easier to find a marmoset without forest than a forest without a marmoset monkey. At the official evaluation report (data from The Ministry of Environment), the population tendency of the common marmoset is stable, although the population size is unknown. It is estimated that the number of mature individuals of this taxon is more than 10.000 and the groups vary in size from 3 to 15 individuals. The extent of occurrence of the species is greater than 20.000 km2 and it is estimated that its area of occupation is greater than 2.000 km2. The Laboratory of Advanced Studies in Primatology (LEAP) is among the five largest centers of primatology in Brazil, being the largest breeding place of the Callithrix jacchus species. Its activities mainly focused on the research developed by the Graduate Program in Psychobiology. The common marmoset has been found increasingly more distant from his area of endemism, with records crossing all the Brazilian continental border and reaching Argentina. The Brazilian Primates Conservation and Research Center (CPB/ICMBio/MMA) accesses the need to expand studies to develop methods for the control and eradication of the species in areas where it is as allochthonous / invasive, especially in those with presence of endangered taxa. The CPB is responsible for the definition of governmental policies for the use, care, and protection of Brazilian primates. New approaches linking field and captive research are uncovering new aspects of traditional subjects such as gomivory, stress and sensory ecology.

SAVERIO CAPUANO, Wisconsin National Primate Research Center | Video | Presentation

The recent development of powerful, new genomic editing techniques has fueled a significant increase in demand for common marmosets (Callithrix jacchus) as biomedical research subjects, while the current supply of animals from established breeding colonies at national primate research centers, academic institutions, and commercial suppliers cannot meet the present or predicted future worldwide demand.  This presentation will provide a summary of the size and number of common marmoset populations currently maintained in North America, South America, Europe, and Japan and will propose ideas for ethically increasing the availability of common marmosets internationally and ensuring the fair and equitable distribution of these animals to scientists funded to utilize them in biomedical and behavioral research.

Zoos accredited by the Association of Zoo & Aquariums collaborate to ensure small populations under their care retain genetic diversity with minimal supplementation from new founder animals from the wild. Termed Species Survival Plans® (SSPs), these programs track the pedigree, medical status, and reproductive histories of animals in Studbooks. The SSP coordinator utilizes Studbook information under the guidance of a Population Biologist to create a Breeding and Transfer plan, a document detailing a multi-year strategy of animal shipments and recommended pairings for offspring based on Mean Kinship, a measure of relatedness of an individual to the entire population. Breeding and Transfer Plans direct populations to reach a goal of retaining greater than 90% genetic diversity for 100 years or 10 generations.

Dissecting the genetic diversity of Japanese’s marmoset colonies

The common marmoset (Callithrix jacchus) is essential for understanding the human brain and for developing knowledge-based strategies for the diagnosis and treatment of psychiatric and neurological disorders. For establishing the primate model for human diseases, we perform massive population genetic analysis for the neuropsychiatric related genes in marmosets in order to identify individuals/families that have spontaneous loss-of-functional (LoF) mutations in the neuropsychiatric genes and aim to make disease marmoset models for the neuropsychiatric disease by crossing the individuals that have a heterozygous LoF mutation. We obtained the polymorphic data from 1328 marmosets across 10 Japanese colonies and identified many candidate individuals that have LoF mutations in a heterozygous manner. Also, we compared the genetic background and composition of marmosets between Japan and US using the available genomic data for further plan to maintain the genetic diversity and found distinct relationships among the colonies between Japan and US. Accumulating such massive polymorphic data in marmosets can give us a useful disease animal model, which can bridge the gap between bench (basic science) and bed (clinical research) and can lead us to understand the biological basis of human neuropsychiatric diseases.

Opportunities to improve genomic information and resources for marmosets

The 2014 publication of the first reference genome sequence for the common marmoset (Callithrix jacchus) provided the starting point for genomic analysis of this species.  Since that time, both the methods available for generating genomic data and the comparative information available regarding other nonhuman primates have advanced significantly.  It is now practical to produce an improved reference genome sequence and associated annotation that will be both more complete and more accurate than the 2014 reference.  In addition, comparative information suggests that a substantial amount of functionally significant genetic variation is likely to be segregating within captive marmoset colonies, and that this naturally occurring variation will impact efforts to use marmosets for a variety of genetic studies.

Analyzing genetic diversity in marmoset colonies

As the marmoset becomes widely used as a model organism in the study of many diseases, maintaining the genetic diversity of the marmoset colonies in the US and around the world becomes an important goal.  A marmoset genotyping chip will facilitate the study of genetic diversity and of future genome-wide association studies.  To design a genotyping chip, detecting single nucleotide polymorphisms (SNPs) in marmoset colonies is crucial.  To discover SNPs, we performed whole genome sequencing of 81 marmosets from 3 colonies (36 from the New England Primate Research Center (NEPRC), 18 from Biomere, and 28 from CLEA Japan).  We also included 9 publicly available whole genome sequences (5 from Southwest National Primate Research Center, 2 from NEPRC and 2 from Wisconsin National Primate Research Center), and ran a computational pipeline that performed multi-sample SNP discovery. We obtained 5.7 million high quality filtered SNPs (the filters include minor allele frequency and read coverage), and after pruning based on linkage disequilibrium, we obtained 147,000 independent SNPs.  These SNPs can be used as a starting point to design a marmoset genotyping chip and can be augmented with SNPs from other colonies.  The SNPs allowed us to analyze the heterozygosity of each of the three colonies and to analyze runs of homozygosity (which could indicate inbreeding) of each animal.  A principal component analysis of the genotypes showed that the colonies are genetically distinct.  We also computed the Fst, a measure of structure in populations, and obtained a value of 0.12.  This indicates that 88% of the total genetic variation is shared among colonies.  These results show that genotyping a much larger number of marmosets from other colonies will allow a better understanding of the genetic landscape of marmosets and could aid in their breeding strategies.

Speaker bio

Ricardo del Rosario is a computational biologist at the Stanley Center for Psychiatric Research at the Broad Institute.  He leads the marmoset genome project which involves the assembly of a new marmoset genome and whole genome sequencing of marmosets at MIT and Broad.  The new marmoset genome assembly, its genome annotation, and whole genome sequences are needed by scientists working on genetic engineering in marmosets.   Before he joined the Broad Institute, he worked as a research scientist at the Genome Institute of Singapore (GIS).  One of his projects at GIS was to study the evolution of regulatory elements in primates.  The marmoset genome was an important species that he used in performing a genome-wide screen for primate-specific constrained sequences.  His work was included in the paper that published the marmoset reference genome. At GIS, he also developed a mathematical method to detect histone acetylation quantitative trait loci in human cohorts.  These are SNPs that affect the acetylation levels of histones (as measured by H3K27ac ChIP-seq) and thus affect the activity of promoters or enhancers. His other experiences include a postdoctoral fellowship at the Max Planck Institute of Biochemistry in Germany, where he created mathematical models of the bioenergetics of an archaeon Halobacterium salinarum, and an Associate Professor position in mathematics at the University of the Philippines.  He obtained his Ph.D. in Applied Mathematics from NC State University.

Session 2: Marmosets as Research Models

CORINNA ROSS, Texas A&M University – San Antonio | Video | Presentation

Marmosets as Translational Models for Aging Studies

While advances in medical care have resulted in increased human lifespan, we have made relatively few advances in increasing human healthspan. Additionally, it is now believed that many of the pillars of aging are associated with diseases such as dementia, frailty, and cancer. Treatment of aging systemically will not only increase life span but also reduce age related disease incidence. The use of an animal model to evaluate cellular, mechanistic and phenotypic processes of aging offers the advantage of being able to control environmental exposure to variables including nutrition and infection, as well as maintain lifelong confirmed medical history of the individual. The marmoset offers a unique nonhuman primate model for aging studies. Marmosets have a short lifespan when compared to other primates, they are relatively cheap to house, have high fecundity, and they are small making them easy and safe to handle for experimentation. Marmosets have been found to display many aging phenotypes that mimic human aging including increased risks of cardiovascular changes, inflammatory disease, and decreases in cognition. The emergence of this animal model is particularly important for those interested in examining the effects of early life environment on aging, evaluating the effects of interventions on aging and age-related disease, and those interested in focusing on cognitive changes associated with aging.

Marmoset-based infectious disease research under biocontainment conditions

The marmoset has emerged as an attractive non-human primate (NHP) model for studying biocontainment infectious diseases agents and most recently as a viable NHP model for high containment infectious disease viruses.  The advantages of the marmoset are that they very often mimic human disease, are smaller in size, provide some cost savings over larger NHPs,  and can require less time consuming husbandry.  They have fewer biosafety considerations since they have fewer known endogenous viruses harmful to humans and in particular, they are not carriers of herpes B virus. Marmosets, as models of human disease, have been examined for a variety of pathogens particularly viral pathogens.  They have been proven effective models for equine encephalitis viruses, coronaviruses (MERS and SARS), Lassa fever virus, filoviruses (Ebola and Marburg viruses) and a surrogate of Hepatitis C virus, GBV.  Marmosets have been evaluated as models for flaviviruses particularly dengue virus and most recently Zika virus.  Marmosets have also been shown to be an effective model for mycobacterium tuberculosis.  In a well-maintained and carefully monitored colony, they rarely show any sero-positivity to known human viruses and thus have been used in Koch’s postulate experiments for novel adenoviruses.  In biocontainment, the marmoset is an excellent model for human disease providing the advantages of a small animal model, the immunological repertoire of an NHP and susceptibility to many wild-type human viruses.

The common marmoset as a preclinical model for neurological disorders

Aging societies face an increasing prevalence of neurodegenerative disorders, like Parkinson’s and Alzheimer’s disease, for which no cure exists. There is also a need to improve current therapies or develop new ones. The paucity of relevant animal models that faithfully reproduce clinical and pathogenic features of neurodegenerative diseases is a major cause for the lack of effective therapies. Our closest relatives, non-human primates -in particular the marmoset (Callithrix jacchus)-, provide an appropriate model for face and predictive validity owing to the close anatomical and physiological proximity to human. We will discuss a (slow-progressive) MPTP marmoset model of idiopathic Parkinson’s disease that recapitulates most of the core pathogenic mechanisms of the human condition as well as the prodromal stage of the disease for early intervention and an immune-activated amyloid-beta model, that makes use of the natural occurring plaque progression in the marmoset, for the most important hallmark of Alzheimer’s disease.

Marmoset models production by genome editing

Genome editing technologies have been enabled us to produce animal models by target gene knock-out. Currently, three kinds of artificial nuclease, Zinc Finger nuclease (ZFN), Transcription Activator-Like Effector Nuclease (TALEN) and clustered regularly interspaced short palindromic repeats / CRISPR associated proteins (CRISPR/Cas9) are available. Since the CRISPR/Cas9 is easy to use, it is the most popular in mouse models production. However, there are several issues to use in marmosets. In this talk, marmoset-specific genome editing techniques will be introduced.

Imaging Brain Anatomy, Function and Disease in Marmosets

The common marmoset (Callithrix jacchus) is a small New World monkey that has gained significant recent interest in neuroscience research, due in great part for its compatibility with gene editing techniques, but also due to its tremendous versatility as an experimental animal model. Neuroimaging modalities, including anatomical (MRI) and functional magnetic resonance imaging (fMRI), complemented by two-photon laser scanning microscopy and electrophysiology, have been at the forefront of unraveling the anatomical and functional organization of the marmoset brain. High resolution anatomical MRI of the marmoset brain can be obtained with remarkable cytoarchitectonic detail. Functional MRI of the marmoset brain has been used to study various sensory systems, including somatosensory, auditory and visual pathways, while resting-state fMRI studies have unraveled functional brain networks that bear great correspondence to those previously described in humans. Two-photon laser scanning microscopy of the marmoset brain has enabled the simultaneous recording of neuronal activity from thousands of neurons with single cell spatial resolution. These neuroimaging techniques have been used to investigate the relationship between brain anatomy and function both in health and in disease models. In this talk, we will review the main results obtained by our group and by our colleagues in applying neuroimaging techniques to study the marmoset brain.

A Philosopher’s Perspective on the Ethics of Transgenic and Chimeric Research on Primates

In this presentation, I provide an outline of how philosophers approach ethical questions related to primate research in general and transgenic and chimeric neuroscience research in particular. I outline the basic ethical concepts and frameworks philosophers use in debates about primate research and discuss which types of empirical knowledge about the capacities of primates are relevant under these different frameworks. Finally, I introduce special concerns bioethicists have raised about concepts such as near‐personhood, telos, and bodily integrity in relation to transgenic and chimeric research.

Prior to Oxford, he worked at the University of Pennsylvania and the University of British Columbia. Adam’s research examines the intersection of ethics and cognitive science and he has written multiple articles about human well‐being and animal welfare. In particular, Adam’s research has examined the significance of the dissociation between the affective and sensory components of pain for philosophical theories of ethics and well‐being. To this end, Adam has written about the relationship between pain and pleasure, the legal and ethical questions that arise from the search for a neural signature of pain in humans, and the capacity for suffering across different species. He also has research examining the ethics of using genetic modifications in nonhuman animals. Previously, Adam organized a workshop on neuroethics and animals, and he is currently co‐editing a book on the topic.

An analysis of the ethical imperative of being cognizant of one’s knowledge prior to commencing research with marmosets

This ethical imperative is driven by the relative fragility of marmosets in captivity, amplified by any adverse outcomes due to ignorance or inadequate resources. Conventional oversight measures, such as regulatory compliance, accreditation, and IACUC activities, are not sufficient to ensure adequate preparedness of a research institution before it begins to use these animals. That, in turn, raises the question of which is better for reliable marmoset care and use: extramural expert confirmation or intramural confidence of an institution’s competence? Various elements of this question will be analyzed, with suggestions offered on how to move forward.

MICHAEL POWER, Smithsonian National Zoo and Conservation Biology Institute | Video | Presentation

Marmoset nutritional needs and daily dietary management

There is a long history of concerns over the dietary management of captive common marmosets. Unfortunately, the literature on rigorous nutritional studies of marmosets is relatively thin. Diets vary across colonies of common marmosets in both ingredients and nutrient levels, which may contribute unnecessary variation in experimental outcomes and may play a role in some of the more common clinical diseases seen in this species in captivity. The goals of this talk are: 1) to provide a basic overview of nutrient needs of marmosets in order to inform diet formulation for animals in captivity (primarily in laboratory facilities) and 2) to provide information on practical feeding programs and options.

I will summarize important features of the natural history of marmosets, touching on evolution, taxonomy, behavioral ecology, and behavior in the wild and in semi-natural captive conditions. I will attempt to apply what we know about these topics to humane care and use of marmosets in biomedically-oriented captive settings.

Speaker bio

Dr. Nancy Caine earned a Ph.D. in Comparative Psychology at UC Davis, studying large social groups of macaques. She did postdoctoral work at the University of Colorado Medical Center before taking a faculty position at Bucknell University in Pennsylvania.  It was there that she began to work with callitrichid primates, doing controlled studies of their reactions to predatory threat. For the last 25 years Dr. Caine has been at California State University San Marcos where she has continued her work with captive populations of marmosets housed in naturalistic environments, publishing studies on topics ranging from the function of color vision to group-mediated anti-predator behavior. She is interested in “translational ethology,” whereby our understanding of the evolved behavioral adaptations of primates can be brought to bear in captive management. Dr. Caine has served in leadership roles in both the American Society of Primatologists (President from 1998 to 2000) and the International Primatological Society (Secretary General from 2008 to 2018).

Controlling Ovarian Cycle Onset in Female Marmosets in the Context of New World Primate Reproductive Endocrinology

Characteristic of anthropoid primates, including humans, female common marmosets exhibit approximately monthly ovarian cycles. In contrast to many anthropoid primates, however, female marmosets ovulate 2-3 oocytes per cycle, enabling atypically high fecundity. Luteolysis is reliably induced by prostaglandin F2alpha analogue and GnRH antagonist, terminating cycles or early pregnancies within 1-2 days. Such control can be performed in consecutive cycles or early pregnancies across many months to years. Rapid, 4h enzymeimmunoassays permit same day confirmation of cycle phase from plasma progesterone concentrations (<10 ng/ml = follicular phase). Exaggerated expression of select cytoplasmic proteins, however, typical of New World primates, diminish access of female sex steroid hormones to intra-cellular cognate receptors and subsequently to response elements on gene promoter sites. Pituitary chorionic gonadotropin (CG) and not luteinizing hormone, enables dominant follicle progression, ovulation and support of 2-3 corpora lutea, while placental CG provides primate-typical pregnancy recognition. Continuing refinement of ovarian hypergonadotropic stimulation protocols will optimize number and quality of oocytes for assisted conception of genetically modified offspring.

Dr. Abbott is Professor of Obstetrics and Gynecology, and Senior Scientist at the Wisconsin National Primate Research Center, University of Wisconsin, Madison. He brings 40 years of experience employing rodent, primate and exotic species models of female reproductive endocrinology to determine pathophysiological mechanisms underlying a variety of reproductive health disorders commonly found in women. He led one of the first studies demonstrating social dominance regulation of ovulation in a female primate, the common marmoset, leading to a series of mechanistic studies delineating sensory, behavioral and neuroendocrinological mechanisms that did not involve stress responses. Additional containment of female marmoset success was found to derive from avoidance of close kin mating and female-mediated infanticide. More recently, Dr. Abbott has explored the molecular underpinnings of female marmoset sexual behavior, to better inform therapeutic development aimed at ameliorating sexual dysfunction in women. Building on his knowledge of female primate ovarian cycles, he has collaborated to develop two rhesus macaque models for the highly prevalent infertility and diabetogenic polycystic ovary syndrome (PCOS) in women: fetal testosterone programming and naturally occurring hyperandrogenism. His current collaborations involve knockdown of estrogen receptor alpha (ERα) expression in the hypothalamus of adult female marmosets using viral vector technology. The aim is to establish ERα as the ER regulating metabolic, sexual and pituitary-ovarian function in female primates, including women, and encourage better targeted therapeutics for regulation of weight, sexual desire and ovulation.

Trials of microbiological control in common marmosets

Microbiological control is one of the important issues in marmoset husbandry. Marmosets have relatively little problems of severe infectious disease these days. However, health problems caused by opportunistic pathogens have remained and SPF in marmosets has been controversial. In our colony, Clostridium difficile infection (CDI) has emerged and fecal microbiota transplantation has been tried to control intestinal microbiota against CDI. On the other hand, we tried highly microbiological control through a caesarian section to generate severe combined immunodeficient marmosets and germfree marmosets. In this talk, I will introduce our experiences in these trails to the following discussions with this issue.

Options for harmonization of Marmoset husbandry – a global perspective

Increasing attention has been given to the influence of housing and husbandry on the behavior and welfare of laboratory animals as well as on the integrity of scientific research. Marmosets have, to some extent, escaped the same genetic, rearing and environmental standardization that is seen with the majority of laboratory rodents. Innovation in enrichment (e.g., outside enclosures, manipulanda, visual and auditory enrichment) is designed to enhance wellbeing. However, the effect of this variation in housing, together with different rearing conditions, weaning policies, husbandry and other practices has not been systematically quantified and its impact on the scientific outcome is not known. To ensure socially well-adjusted marmosets that can cope with the challenges they will face in experimentation and to ensure valid and reliable scientific data, greater harmonization in marmoset husbandry should be encouraged.

International harmonization of existing guidelines for the use of marmosets is essential to provide good principles to promote high standards in the husbandry of marmosets used in research and teaching. In addition, communication and partnership among national, regional, and international organizations will ensure the global harmonization of the use of marmosets. Although each country should be able to maintain an animal welfare oversight system that reflects its own culture, tradition, religion, laws, and regulations, it is also important that each country recognizes and implements international core principles for the care and use of marmosets.

At the BPRC, he was and is involved in general animal care, enrichment programmes, reviewing research protocols, disease monitoring (preventive medicine), new treatment options for the animals, breeding programmes and public education. Over the years, he has worked with several primate species including owl monkeys (Aotus trivirgatus), chimpanzees (Pan troglodytes), cotton top tamarins (Saguinus oedipus), cynomolgus macaques (Macaca fascicularis), rhesus monkeys (Macaca mulatta) and marmosets (Callithrix jacchus). Although knowledge of primate medicine has increased considerably over the last decades, especially in the field of welfare management, improvements can still be made. Jaco started a PhD programme aimed at further improvement of veterinary care and welfare management of marmosets, leading to the animals’ better health. In 2017 he successful finished his PhD at the University of Utrecht, the Netherlands, entitled ‘veterinary care and welfare management of common marmosets’. Apart from his projects on marmosets, he was and still is actively involved in research in the other nonhuman primate species at the BPRC to improve veterinary care and welfare management. On these topics he set up a number of (inter)national collaborations with veterinary groups, which have already resulted in various joint publications and invitations to present his research.
