WebNov 11, 2024 · Previous work established culture conditions in which pluripotent stem cells can be driven stepwise first into an epiblast‐like state and subsequently into a primordial germ cell‐like (PGCLC) state. These PGCLCs, when placed in an appropriate somatic gonadal milieu, are capable of producing mature gametes (Kurimoto & Saitou, 2015).

WebFeb 2, 2024 · The unipotent stem cells that can divide and produce gametes are called germ cells. The gametes of haploid sex cells are produced by a germ cell, which undergoes meiotic cell division and produces genetically unique gametes. These gametes fuse during fertilization and form diploid zygotes.
