Scientists have found a single protein—Ptbp2—controls a network of over 200 genes central to how developing sperm move and communicate. The protein works by regulating how RNA is processed during each stage of sperm development.

Germline cells are the only cells that develop into eggs or sperm, while somatic cells develop into the body. Progenitors of the germline, known as primordial germ cells (PGCs), differentiate into eggs or sperm after embryonic ...
