interna theca cell
interna theca cell
"A specialized theca cell that forms the inner, highly vascularized layer of the theca surrounding ovarian follicles. Originating from progenitor theca cells, the theca interna cell is steroidogenic, playing a crucial role in the production of androgens, which serves as a precursor for estrogen synthesis in granulosa cells. This cell expresses luteinizing hormone receptors, enabling it to respond to hormonal signals that regulate steroidogenesis."
