Abstract:The rat, as well as the mouse, is one of the most valuable experimental animals for biomedical and physiological research. There are numerous valuable mutant rats including transgenetic strains. Cryopreservation of rat oocytes and sperm as haploid germ cells is a key technology for banking the genetic resources efficiently. The aim of the present study was to examine survival of vitrified/warmed oocytes and developmental competence of resultant zygotes in the rat. Rats used in the present study were all Wistar… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
