Maintenance of Human Primordial Germ Cell-Like Cells in a Long-Term Culture System.

Abstract

Primordial germ cells (PGCs) are the earliest form of mammalian germ lineage. In humans, PGCs are present during a very early and limited window in development, limiting the ability to study fundamental developmental steps in human reproductive biology. However, recent advancements in generating in-vitro models of gametogenesis have allowed the field to generate human primordial germ cell-like cells (hPGCLCs). In this chapter, we will review the generation of hPGCLCs using the incipient mesoderm-like cell (iMeLC) protocol and the subsequent expansion of hPGCLCs in a long-term culture system.
