0 {2 E9 a; u1 H: v4 QOn the cover: The Black Tortoise (Xuan Wu) is a Chinese mythological symbol of reproduction, adapted here to depict the mammalian life cycle (ring) maintained through mating (snake and tortoise), with the red germ cell at the center vital for transmitting genetic information from one generation to the next. The transcriptional and epigenetic landscape of developing human primordial germ cells, provided by Guo et al. (pp. 1437–1452), Gkountela et al. (pp. 1425–1436), and Tang et al. (pp. 1453–1467), reveals a distinct transcriptional network and progressive and conserved global erasure of DNA methylation and suggests potential hotspots of transgenerational epigenetic inheritance. This work paves the way toward deciphering the complex epigenetic reprogramming of the germline, with the aim of restoring totipotency in fertilized human oocytes.
