What is the Origin of Granulosa Cell?

The term derives from the Latin word "granulum," meaning small grain, referring to the characteristic granular appearance of these cells when viewed microscopically. These cells are integral components of the mammalian ovary and the follicular unit, which is the basic functional structure of the female gonad. Their essential role in steroidogenesis and oocyte support has been understood since the early study of reproductive endocrinology and histology.

What is the Mechanism of Granulosa Cell?

Granulosa cells are the primary site of estrogen biosynthesis within the ovary, executing the crucial step of aromatizing androgens, which are supplied by the adjacent theca cells, into estrogens. This process is tightly regulated by pituitary gonadotropins, specifically Follicle-Stimulating Hormone (FSH), which stimulates the expression and activity of the aromatase enzyme. They also produce essential growth factors and paracrine signals for oocyte maturation and, after ovulation, differentiate into luteal cells to produce progesterone.

Granulosa Cell

Meaning

The Granulosa Cell is a specialized somatic cell type found within the ovarian follicle, playing an indispensable role in the development of the oocyte and the production of sex steroid hormones. These cells form crucial layers surrounding the developing egg, communicating intimately with the oocyte and the surrounding theca cells through paracrine signaling. Their health and functional capacity are directly proportional to the quality and viability of the ovulated egg and subsequent corpus luteum function.
