Figure 5From: Differential expression of pluripotent and germ cell markers in ovarian surface epithelium according to age in female miceSmaller oocyte-like structures developed in 3-week postcultured OSE of different aged mice. Ovarian stem cells spontaneously increased in size and differentiated into oocyte-like structures (arrow head) in 3 weeks postcultured OSE of young (A-C) and aged mice (D-F). Single or clusters of epithelial cells (arrow) (G) and oocytes (asterix) (H-I) were found with OSCs during scraping of OSE. Scale bar = 20 μm.Back to article page
