WebThe lineage of germ cells is called the germline. Germ cell specification begins during cleavage in many animals or in the epiblast during gastrulation in birds and mammals. After transport, involving passive movements and active migration, germ cells arrive at the developing gonads. WebThe germinal epithelium undergoes mitotic division to produce a series of cells like primary spermatocyte which undergo meiosis to form secondary spermatocyte, speramatids and sperm. Sertoli or sustentacular cells or nurse cells: supporting long, slender, pyramidal cells that help and nourish various stages of spermatogonia.
