摘要

When stem cells in the rat testes are at a developmental crossroads, they are able to make their decision independently of their surroundings, according to Zhuoru Wu and her colleagues at the University of Texas Southwestern Medical Center in Dallas.rnProgeny of spermatagonial stem cells have two choices: become stem cells or differentiate into sperm. Some models predict that the cells' decision is determined by environmental cues.
