Follicle-stimulating hormone induces terminal differentiation in a predifferentiated rat granulosa cell line (ROG).

abstract：:The hypothalamic-pituitary-adrenal axis involves timed signaling between the hypothalamus, pituitary, and adrenal glands and back to the brain, causing an inherently oscillating system. Corticosteroids such as corticosterone (CORT) are secreted in a circadian rhythm, characterized by low and high levels at the start o...
