A germ cell is any cell that gives rise to the gametes of an organism that reproduces sexually. In many animals, the germ cells originate in the primitive streak and migrate via the gut of an embryo to the developing gonads.

WebIn this sense, germ cells are an immortal cell line beyond generations, in contrast to a somatic cell lineage, which is destined to die after a fixed number of mitotic divisions, or disappear with the death of the organism. A germ-cell line contains both male and female gametes, and their precursor cells.

In biology and genetics, the germline is the population of a multicellular organism's cells that pass on their genetic material to the progeny (offspring).
