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.
