Achieving High Throughput Repositories for Biomedical Germplasm Preservation Workshop—April 10, 2007

Workshop Summary

On April 10–11, 2007, the National Center for Research Resources (NCRR) sponsored a workshop entitled, Achieving High Throughput Repositories for Biomedical Germplasm Preservation, at the NIH Natcher Conference Center in Bethesda, Maryland. The workshop was co-sponsored with the National Institute of Child Health and Human Development.

The purpose of the workshop was to assess the status of germplasm cryopreservation for the following animal models for translational research: mouse, rat, pig, nonhuman primate, and aquarium fish. A total of 75 workshop participants represented diverse areas of expertise, including cryobiology, animal germplasm preservation, and associated areas of reproductive physiology, gamete and embryo biology, biosecurity, animal health, and epigenetics. In addition, NIH extramural and intramural staff, USDA scientists, and representatives from commercial companies contributed to the discussions.

The workshop was divided into four sessions, each with ample time for discussion. The first session consisted of four short presentations summarizing the current state-of-the-art of the cryopreservation of sperm, oocytes, embryos, and other forms of germplasm, for each target species. The second session consisted of two presentations from commercial companies with experience developing high throughput technologies for preservation of germplasm, and an example of successful application by the USDA's Animal Germplasm Program. The third session consisted of five panel presentations on cryopreservation methods and optimization of protocols. The final session consisted of five panel presentations on physiological, reproduction, biosecurity, disease and the interplay of genetics/epigenetics/environment.

Workshop participants were asked to address the following issues:

  1. What are the current problem areas for applying germplasm preservation to each of the target species?
  2. What are the current gaps in current knowledge of germplasm preservation?
  3. Are there novel or emerging technologies that might supersede or overcome current germplasm preservation limitations?
  4. Which species and types of germplasm would be amenable for high throughput germplasm preservation?
  5. Provide specific recommendations on the most promising areas for future research on germplasm cryopreservation technologies.
