Short-term storage of rabbit embryos at 4 degrees C.
A simple method for storing preimplantation mammalian embryos was tested under conditions which could be easily maintained inside an ordinary refrigerator set at 4 degrees C. No significant loss of viability occurred when rabbit embryos were stored at 4 degrees C for 7 days and either cultured in vitro at 37 degrees C or transferred to recipient does. Significant losses occurred when embryos were stored for 10 days or longer before culture at 37 degrees C (P < .01). Stored embryos transferred to recipients had a significantly longer average gestation period than embryos transferred without cold storage (P < .05).
