Shooting the messenger: how one protein allows germ cells to develop

Researchers have identified a molecule that guides the formation of eggs and sperm by preventing a host of factors related to cell death and inflammation from killing the precursors to these cells. Their findings reveal new knowledge about how a mutation in this molecule leads to male sterility.
