Definitions for "Germline cells"
cells of the gonadsthat are devoted to the production of reproductive cells (gametes).
Cells responsible for the production of gametes. In humans, the egg and sperm cells. Germline cells are haploid; they contain 23 chromosomes.
Cells that arise from the inner cell mass and are irreversibly committed to give rise to eggs or sperm. Primitive germline cells (which are germline stem cells) migrate from the posterior of the early postimplantation embryo to the developing gonads, known as genital ridges, where they commit to spermatogenesis (in testes) and oogenesis (in ovaries).
