WebThe gonocytes specifically adhered to Sertoli cells, isolated from 21 to 23-day-old rat testes; this adherence was necessary for their survival in vitro. Addition of follicle-stimulating hormone and testosterone to these cultures did not increase the viability of the gonocytes. Serum was found to be deleterious to the germ cells.
WebGerm cells are highly specialized cells that transmit ge-netic information to subsequent generations. In mouse, primordial germ cells (PGCs) are segregated from the so-matic cell lineages at early gastrulation. These PGCs, once generated, continue to proliferate and migrate through the somatic tissues to eventually reach the fu-ture gonads.
