Developing germplasm repositories for aquatic biomedical model organisms


At the Aquatic Germplasm and Genetic Resources Center at Louisiana State University AgCenter we aim develop sperm repository capabilities for Ambystoma mexicanum, Xenopus laevis and Aplysia californica, collectively known as the "HUB project".

Storage of cryopreserved germplasm in repositories can provide a way to protect transgenic and mutant lines and reduce the number of live animals held within a stock center. In collaboration with the Ambystoma Genetic Stock Center (University of Kentucky), the National Xenopus Resource (Woods Hole Marine Biological Laboratory) and the National Resource for Aplysia (University of Miami), we aim to develop a high-throughput cryopreservation pathway that is both scalable and generalizable, integrating processing and quality management to establish repository capabilities for these species.
