Unlike lower vertebrates, the developing mammalian follicle is composed of more than one layer of GC.
Our results suggest a possible role for BMPs in follicle atresia.
The promoters of several genes induced by FSH in Sertoli cells and granulosa cells, including c-Fos, transferrin, follicle stimulating hormone receptor, SF-1 genes and the RIIβ gene, contain functional E-box elements [ 21 22 23 24 ] . We found that several USF complexes containing full-length USF1 and USF2 as well as truncated versions, are formed at the consensus E-box/HLH-binding element in the RIIβ promoter in Sertoli cell nuclear extracts.
In this regard, a recent study has demonstrated the ability of BMP-4 to inhibit cyclic AMP-stimulated androgen production by the cultured human theca cell line, presumably by activating BMP receptors (BMPR-IA, -IB, and -II) which are expressed in these cells [ 34 ] . Because theca derived androgen is required for follicle estrogen biosynthesis and has been implicated in ovary pathology [ 35 ] , it will be interesting to determine how the expression and functions of these TIC-specific BMPs are integrated into the overall processes of physiology and pathophysiology.
Critical windows of activity in the sheep include: somatic ovarian tissue differentiation (from the gonadal ridges of the mesonephros) and growth (up to Day 50 of gestation); germ (from yolk sac endoderm) and pregranulosa (derived from the ovarian surface epithelium) cellular migration into and colonization of the ovaries (Days 30-65); clonal expansion of oogonia (Days 35-75); onset of meiosis and arrest (by Day 80) at the dictyate stage of prophase (the first division of meiosis is not completed until ovulation); and ovigerous cord regression and primordial follicle emergence (Days 65-110) [ 1 31 32 33 ] . It seems apparent that germ cells are particularly vulnerable to a metabolic insult when in the phasic transition between mitosis and meiosis I.
