[A new culture method for primordial germ cell].

Abstract

To investigate the new method that the primordial germ cells (PGCs) can long time propagate, grow and keep potency of differentiation in vitro. PGCs were co-cultured with Sertoli cells (SCs) or with homologue fibroblasts from genital ridge. When co-cultured with SCs, PGCs colonies and times of transfer of culture were greater than those co-cultured with homologue fibroblasts. At present PGCs of co-cultured with SCs have succeeded in subculturing to the 51 generation. SCs can availably enhance propagating ability as well as a long period of time maintain the characteristic of PGCs.
