Theca cell
Theca Cell
Theca cells (pronounced: thee-ka cells) are a group of cells found in the ovary of female mammals. They play a crucial role in the development of the follicle and the production of hormones necessary for reproduction.
Etymology
The term "theca" is derived from the Greek word "θήκη" (thēkē), which means "case" or "sheath". This refers to the protective role these cells play in the development of the ovarian follicle.
Function
Theca cells are involved in the production of androgens, which are then converted into estrogen by the granulosa cells. This process is essential for the maturation of the oocyte and the preparation of the uterus for pregnancy.
