Sertoli cells
Sertoli Cells
Sertoli cells (pronunciation: ser-TOE-lee cells), also known as nurse cells, are a type of cell found in the testis. They are named after the Italian physiologist Enrico Sertoli, who first described them in 1865.
Etymology
The term "Sertoli" is derived from the name of the Italian physiologist Enrico Sertoli. The term "cell" comes from the Latin cella, meaning "small room".
Function
Sertoli cells are essential for the development and maturation of spermatozoa. They provide physical support, nourishment, and regulatory signals to developing spermatogenic cells. Sertoli cells also form the blood-testis barrier, which protects the developing sperm from harmful substances in the blood.
