Table1. Production of SDR rats by implanting Rag2 SSCs into sterile males.
Four recipient males were transplanted with genetically modified SSCs. Only one recipient (526300) had no surgical complications and had good fill of testis with modified SSCs. Only that recipient produced pups when mated with wild type females.
