Theca of follicle - Wikipedia
Theca cells are a group of endocrine cells in the ovary made up of connective tissue surrounding the follicle. They have many diverse functions, including promoting folliculogenesis and recruitment of a single follicle during ovulation. [2] Theca cells and granulosa cells together form the stroma of the ovary.
Ovarian Follicular Theca Cell Recruitment, Differentiation, and …
Theca cells within the theca layer of growing follicles are derived from two different sources in the embryonic gonad; mesenchymal cells migrating into the ovary from the mesonephros region become the steroidogenic cells, and WT1 + stromal cells indigenous to the embryonic ovarian medullary region become fibroblasts, perivascular smooth muscle ...
Theca: the forgotten cell of the ovarian follicle - PubMed
Theca cells function in a diverse range of necessary roles during folliculogenesis; to synthesize androgens, provide crosstalk with granulosa cells and oocytes during development, and provide structural support of the growing follicle as it progresses through the developmental stages to produce a ma …

Theca cells function in a diverse range of necessary roles during folliculogenesis; to synthesize androgens, provide crosstalk with granulosa cells and oocytes during development, and provide structural support of the growing follicle as it progresses through the developmental stages to produce a mature and fertilizable oocyte.

2018年2月1日 · Lastly, we will integrate what is known about theca cells from mouse models, human-derived theca cell lines from patients who have PCOS and patients who do not have PCOS, and microarray analyses of human and bovine theca to understand what pathways and factors contribute to follicle growth as well as to the abnormal function of theca.

2007年1月1日 · Two-way signalling between oocytes and somatic theca cells with growth factors is shown to play a pivotal role in preantral folliculogenesis and atresia. Thus, theca cells have a more significant role in follicular function than previously thought.
Ovarian theca and granulosa cells, together with oocytes, are the three distinct anatomical constituents of ovarian follicles with specific functions in folliculogenesis, steroidogenesis and oogenesis (Gougeon, 2004).

2007年5月29日 · The role of theca cells in every aspect of ovarian follicular function is reviewed. A distinguishing feature of theca cells may be their ability to initiate follicle growth on differentiation from cortical stromal cells, stimulate follicle growth by granulosa cell mitosis through FSH-induced androgen receptor, and cause androgen-stimulated ...
Follicular Theca (of Late Primary Ovarian Follicle)
As epithelial cells within the follicle continue to proliferate, stromal cells immediately external and adjacent to the basement membrane form a connective tissue sheath called the follicular theca. The theca eventually differentiates into the theca interna and …
