Archived Workshop Reports

To augment and expand upon the findings of the Nonhuman Primate Evaluation and Analysis Part 1: Analysis of Future Demand and Supply study report, which was derived from historical analyses, supplier interviews, and user surveys, an expert panel forum was convened by the NIH on “Challenges in Assessing Nonhuman Primate (NHP) Needs and Resources for Biomedical Research.” A forum was conducted August 23-24, 2018 and brought together program officers from the NIH ICOs that sponsor the majority of NHP studies, leading researchers who use NHPs and represent a broad spectrum of scientific areas, and NHP resource managers from the academic, government, and commercial sectors. The objectives of the meeting were to:

• Forecast the future uses of NHPs in biomedical research
• Discuss and determine the scientific advances that are driving the future research
• Define the relevant and emerging NHP models that will be required for future biomedical advances
• Assess the capabilities of the existing resources and their ability to adapt to future needs, including an examination of the timeframe needed for expansion and, if expansion is not possible, what additional resources or infrastructure would be required
• Address the challenges in the resource planning process

The forum was designed with the assistance of an organizing committee comprised of experts in NHP research and resource management and was intended to examine demand and supply from the perspective of each of the three groups of attendees: program sponsors who broadly generate demand based on their funding priorities, researchers who have specific NHP needs, and resource managers who must manage their breeding colonies and provide specialized populations and research capabilities to meet the needs of researchers. The discussions and potential solutions identified by forum participants were further evaluated by the organizing committee after the conclusion of the meeting and synthesized into a set of key recommendations for NIH consideration.

“Strengthening Research Resources: Integration, Innovation, and Standardization,” the Twelfth Comparative Medicine Resource Directors Meeting, was held August 7-8, 2018 in Rockville, MD. All Resource Directors funded by the Office of Research Infrastructure Programs (ORIP)/Division of Comparative Medicine (DCM) were invited to attend. This biennial meeting offers a forum for the exchange of information among grantees and NIH Program Officers provide useful information to DCM-funded Resource Directors and for developing synergistic working groups, interactions, and collaborations. A primary objective was to generate broad interests in Resources, discuss “lessons learned,” and to convey a sense of what’s been done and what can be done in the future. Another important objective was to allow Resource Directors the opportunity to discuss optimization of administrative processes. ORIP Program Officers and others from various NIH Institutes, Centers, and Offices (ICOs) contributed to scientific discussions to further enhance national use of DCM-funded resources.

On July 30, 2018, the Office of Research Infrastructure Programs (ORIP) convened a workshop on “Defined Reference Diets for Zebrafish and Other Aquatic Biomedical Research Models: Needs and Challenges”.  Aquatic animal species, such as zebrafish (Danio rerio), are powerful models for studying human development, behavior, genetics, and disease. The ability to produce transgenic and mutant lines provides biomedical researchers with many options for developing models of human diseases and for developing relevant therapeutic approaches. Different facilities and laboratories use a variety of diets and feeding protocols to maintain these models. In many laboratories zebrafish are reared with a combination of live feed (ex vivo) and/or one of many undefined commercial diets. Commercial diets used in zebrafish husbandry differ significantly in ingredient and nutrient composition and often contain preservatives, lakes, dyes, antinutritional factors, or bioactive food compounds. Studies indicate that the length, weight, sexual maturation, fecundity, and mortality of zebrafish can vary significantly with different diets. Unfortunately, impacts of diet on zebrafish health and behavior and corresponding implications for zebrafish research outcomes are not well described. Currently, the daily dietary nutrient requirements of almost all nutrients have not been investigated. There is also no consensus among aquatic facilities, researchers, and commercial vendors on nutritional requirements at various life stages (i.e., larval, juvenile, and adult) or for particular research applications to minimize husbandry variations among aquatic facilities or laboratories. Complicit in this lack of consensus is a community-wide lack of understanding of the role of nutrition in animal development, health, and research outcomes. To address this gap, the Office of Research Infrastructure Programs (ORIP) is sponsoring a workshop to bring together members of the zebrafish scientific community, with expertise in zebrafish and other aquatic and relevant models, for a day of discussion. The workshop attendants will assess the needs and challenges of developing defined diets and optimized feed management strategies that will support normal zebrafish development and physiology and will facilitate the analysis of phenotypes in a standardized nutritional environment. Standardization and education will promote rigor and reproducibility in some zebrafish studies and enhance the power of zebrafish and other aquatic models in biomedical research.

Objectives:

• Review diet development strategies, where available, in other biomedical model species.
• Assess the current nutrition status of zebrafish.
• Describe the need for defined diets for maintenance and experimental stocks, including assessment of life stage requirements.
• Discuss the potential impact of defined diets on genetic stocks used in biomedical research, their effect on development, physiology and expressivity of disease/mutant phenotypes.
• Identify obstacles and evaluate strategies that may lead to a successful consensus, acceptance, and implementation of defined diets among the different scientific community stakeholders.
• Define an educational approach to informing the community and associated partners (journals, organizations, granting agencies, etc.)
• Determine whether/how the approach to develop a defined diet for zebrafish could be applied to other aquatic models, and animal models in general.

Speaker Presentations

• Session 1 Videos: Historic perspectives, current diets, ingredient considerations, and feeding management in the husbandry of zebrafish and other animal models: a comparative analysis.
• Session 2 Videos: The impact of diet variation on health and experimental outcomes of zebrafish and other aquatic models.

On September 11-12, 2017, the Office of Research Infrastructure Programs (ORIP) convened a workshop “Zebrafish and Other Fish Models: Description of Extrinsic Environmental Factors for Rigorous Experiments and Reproducible Results”. The workshop brought together stakeholders, including facility managers, veterinarians, investigators, journal editors, and representatives from industry, for plenary and break-out sessions on how to account for extrinsic environmental factors. Specifically, the sessions focused on the effects of external environmental conditions on experimental outcomes and the need to strengthen experimental data with extrinsic environmental factors. The participants addressed questions on how to collect, manage, and share such data to benefit facilities and to improve robustness and reproducibility of experiments. The participants developed a draft of guidelines on extrinsic data formats and contents for inclusion in publications; the guidelines will be shared with a broader peer community for comments and edits, before they are published as a white paper.

On September 6, 2017, the Office of Research Infrastructure Programs (ORIP) at National Institutes of Health (NIH) convened a workshop on the “Tagging and Identification of Animal Resources.” The goals of the workshop were to provide participants with (1) a thorough review of the current challenges and possible solutions for the reporting and unique identification of research resources, including model organisms used in biomedical research; (2) an overview of the Resource Identification Initiative (RII or Initiative) to create and maintain biological resource identifiers for NIH-supported animal repositories; and (3) a hands-on session for Resource Directors and NIH staff on acquisition and use of unique Research Resource Identifiers (RRIDs) to identify research resources and conduct citation analysis of their usage. Participants included representatives from academia, industry, and publishing. 

The Cryopreservation of Aquatic Biomedical Models Workshop was held on January 7, 2017 in Birmingham, Alabama. Aquatic animal species such as zebrafish, medaka, Xiphophorus, and Xenopus are increasingly valuable to biomedical researchers because they provide critical clues to the biological mechanisms that underlie human health and disease. Although considerable resources have been invested to generate transgenic, knockout, and mutant lines of many of those aquatic species, reliable and cost-effective approaches for long-term preservation of these valuable lines are still lacking. Currently, cryopreservation of sperm is the sole and proven method for the long-term maintenance in many aquatic models, with no other approaches available to aquatic researchers. To address this gap, the National Institute of Health’s Office of Research Infrastructure Programs (ORIP) sponsored a workshop, whose objectives were to (1) assess the status of germplasm cryopreservation in various aquatic models; (2) identify the obstacles, opportunities, and priorities that may address the need for improved methods; and (3) evaluate novel and emerging research and technologies that might lead to the successful preservation of other germplasm formats. Approximately 25 participants, including experts in the field of cryopreservation of aquatic models, representing the cryopreservation scientific community at large attended the workshop, despite the severe weather that affected the area where the workshop was held. Discussions during the different sessions resulted in specific, actionable recommendations to ORIP, as described in the accompanying report.

Drosophila melanogaster is widely used in the biomedical research community to study development, model human diseases and undertake high-throughput drug discovery. However, reliable and cost-effective approaches for long-term preservation of Drosophila stocks are lacking. To address this gap, the Office of Research Infrastructure Programs in the Division of Program Coordination, Planning and Strategic Initiatives and the National Institute of Neurological Diseases and Stroke co-sponsored a workshop titled “Cryopreservation of Drosophila Strains” in Orlando, Florida on July 13, 2016. The objective of this workshop was to evaluate the potential and practicality of developing efficient preservation methods for long-term storage of Drosophila stocks.

The Division of Comparative Medicine (DCM), within the Office of Research Infrastructure Programs (ORIP) / DPCPSI / NIH-OD, funds Special Emphasis Research Career Awards (SERCAs) in Pathology and Comparative Medicine. These K01 awards are intended specifically to assist graduate veterinarians who have experience in animal/comparative research to become independent investigators in areas related to biomedical science. Since its inception more than 30 years ago, an independent evaluation of the program has not been done. Therefore, in 2012 the DCM assessed the extent to which the program is achieving its original goals.

In the “pre-genomic” era, efforts to functionally annotate human and animal genomes provided information regarding the structure and biological activity of individual genes, leading to a better understanding of the genetic basis of a variety of human monogenic diseases. In the “post genomic” era, sequencing of entire genomes and development of complex bioinformatic tools such as the human HapMap have revealed specific alleles associated with monogenic as well as complex diseases in humans. One of the most frequently used approaches to verify that particular genetic changes lead to human disease is to recapitulate and test these changes in genetically-modified animal models.
