Composition of the BM in early stage follicles in human ovarian tissue. (A) Histological analysis of human ovarian tissue revealed an extracellular BM (white arrows) surrounding primordial, early primary, primary and secondary follicles. (B) Collagen IV (green) expression in the BM (green arrows) of primordial, early primary, primary and in secondary follicles. (C) Laminin (green) expression in the BM (green arrows) of primordial, early primary, primary and in secondary follicles. (D) Fibronectin (green) expression in the mesenchymal compartment of the ovarian cortex. Sporadically, we observed fibronectin expression in the BM of secondary follicles (green arrow). Scalebars are 25Ā Ī¼m.
