Activin A in Mammalian Physiology | Physiological Reviews
Activin A interacts with ECM components in the process of follicle growth and development ( 58, 321 ). Along with other TGF-β superfamily members, activin A downregulates some microRNAs in human and murine granulosa cells, and this indirect mechanism improves cell growth and survival ( 191, 449 ). 3.
