A Sertoli cell is a cell found in the testes. Its main function is to help the developing sperm cells through the stages of spermatogenesis - the process of turning stem cells into sperm. It was also called the "mother cell." The cell also helps in the creation of stem cells.
Sertoli cells get their name from Enrico Sertoli, an Italian physiologist. He discovered them while studying medicine in the University of Pavia, Italy. He published a description of this cell in 1865. As of 2006, two textbooks have been published that are almost entirely about the Sertoli cell .
