From: Unraveling the microRNAs, key players in folliculogenesis and ovarian diseases
microRNA regulates the folliculogenesis. Blue text represents the upregulated miRNA and red text represents the downregulated miRNA arranged key steps in the follicular development process. This includes the development of primordial follicles from pre-granulosal cells, and progression through the stages of primary, secondary, and antral follicle development, with some follicles experiencing atresia. The pre-ovulatory follicle, influenced by luteinizing hormone (LH) and follicle-stimulating hormone (FSH), undergoes ovulation and transitions into the luteal stage
