Primitive oocyte-like cells (arrows) developing in ovarian surface epithelium cell cultures set up by ovarian cortex biopsy scrapings: (a, b) among epithelial cells, (c) attached to autologous ovarian fibroblasts, (d, e) oocyte-like cells, (f) growing primitive oocyte-like cell with zona pellucida-like structure, (g) oocyte-like cells, and (h) primitive oocyte-like cell attached to fibroblast. Scale bars: (a, b) 100 μm, (c–h) 50 μm. Legend: e: epithelial cells, F: fibroblast, o: oocyte-like cell, and zp: zona pellucida-like structure.
