This Request for Information (RFI) seeks input on current challenges and key bottlenecks in the use of marmosets as animal models in biomedical research. The principal objectives include identification of the needs for species-specific biologic reagents, genetic and behavioral analytic tools and technologies, and other crucial resources that would advance the use of marmosets in research and facilitate the translation of modalities in this organism.


Nonhuman primates (NHP) are the closest evolutionary relatives of humans, with whom they share anatomical, physiological, and gene interactions features. The common marmoset (Callithrix jacchus) is of increasing importance for biomedical research worldwide. This New World primate is known for cooperative social behavior, cognition, and communication, which potentially makes it a good model organism to help understand a wide range of human diseases. Marmosets are smaller and easier to house than rhesus macaques and give birth twice a year versus once every year or two years, aiding multi-generational experiments. Because marmosets mature and age more quickly than bigger monkeys, they are potentially also a good model organism to study development and aging. As a nonhuman primate species with several unique reproductive, physiological, and behavioral advantages, marmosets are uniquely positioned to accelerate progress in biomedical research. Additionally, the marmoset’s brain has fewer gyri than a macaque s, making it easier to image or record activity from its surface.

The marmoset as a research model has enjoyed substantial growth over the past decade largely through grass-roots, researcher-initiated projects. While these ventures have been remarkably productive, several bottlenecks must be addressed for the model to reach its full potential as a keystone system for addressing NIH’s stated goal to enhance health, lengthen life, and reduce illness and disability in humans.

In response to the unprecedented growth in demand for marmosets following reports of genome editing and successful propagation of transgenes in marmoset offspring, NIH has launched new initiatives (cooperative agreements) to expand the number of marmoset colonies and to optimize their housing, breeding, and use in research.

NIH is now seeking stakeholder feedback to guide the development of priorities to accelerate research using marmosets as models of human diseases and to facilitate the translation of these findings into human conditions and treatment. This Notice seeks to solicit public comment on the challenges, gap areas, and bottlenecks experienced by the marmoset research community. Feedback obtained through this Notice and other outreach efforts will help to inform the development of research and infrastructure priorities for biomedical research involving marmosets as a model organism.

Information Requested

Stakeholder feedback is requested on any or all, but not limited to, the following topics:

  • Development and distribution of key biological reagents and tools that would facilitate the use of marmosets as animal models and accelerate translation of results
  • Types of tools and biomarkers to facilitate physiological and behavioral studies in marmosets
  • The reference genome and sequence annotation are expected to be available to the research community soon--will this be sufficient?
  • Identified needs in relation to improving genetic diversity, animal husbandry, diet, and shipping of animals between sites
  • Information on other key areas where NIH can facilitate research using marmosets
