Figure 2

Representative micrograph of SEM of VCC (fractured samples) in pre- and periovulatory follicles. In the left panel (A, B, C) the vascular plexus (with inner, middle and outer networks) is showed. The right panel (A', B', C') shows the microvasculature of the inner capillary network. Inserts in A', B', C' illustrates the angiogenic figures (arrowhead = budding; arrows = sprouting; asterisk = infolding-intussusceptive). Preovulatory follicles were isolated 60 h after eCG (A, A'), and periovulatory follicles were isolated 18 h (B, B') and 36 h after hCG (C, C'). c = capillaries; a = arteriole; v = venule; IN, MN and ON = inner, middle, and outer network, respectively. r = resin leakage artefact. Bar = 100 μm. Bar in insert panel = 25 μm.
