  • Title: "A narrow bridge home": The dorsal mesentery in primordial germ cell migration.
    Author: Hen G, Sela-Donenfeld D.
    Journal: Semin Cell Dev Biol; 2019 Aug; 92():97-104. PubMed ID: 30153479.
    Abstract:
    Specification of primordial germ cells (PGCs) in all vertebrates takes place in extragonadal sites. This requires migration of PGCs through embryonic tissues towards the genital ridges by both passive and active types of migration. Commonly, colonization in the genital ridges follows migration of the PGCs along the thin tissue of the dorsal mesentery. Here we review the anatomy of the dorsal mesentery, the role it plays in migration of PGCs, and the interactions of PGCs with different cell types, extracellular matrix and signaling pathways that are all essential for attraction and orientation of PGCs along the dorsal mesentery towards the gonad anlage.
