2. Figure 1
Reproductive profile and outcome of a combined program of follicle culture and IVF using ovarian follicles from adult (8–11 weeks old) and aged (63–67 weeks old) C57BL/6 mice and the morphology of the follicles and oocytes during in vitro culture. (A) Reproductive profile and outcome of assisted reproductive technology (ART) (B) Morphology of growing follicles and developing oocytes derived from in vitro cultured follicles: (a, e) pseudoantrum formation during follicle culture; (b, f) mature oocytes after follicle culture; (c, g) 2-cell embryo; (d) blastocyst; (h) 8-cell embryo. No significant differences in morphology were detected between oocytes derived from the follicles retrieved from aged and those retrieved from adult mice. Scale bars = 60 μm.
