When follicles are recruited to preovulatory development by FSH, their granulosa cells develop LH receptors functionally coupled to aromatase activity and inhibin production.
WebApr 13, 2024 · Preliminary results from in vitro studies indicate that myo-Ins increases FSH receptor and aromatase synthesis in granulosa cells, probably through a FSH-independent mechanism of action. In fact, myo-Ins also increased the transcription of aromatase in breast cancer cells, even in the absence of any previous FSH administration . These results ... WebGranulosa cell.
