Fig. 2From: Bone marrow-derived mesenchymal stem cells combined with gonadotropin therapy restore postnatal oogenesis of chemo-ablated ovaries in rats via enhancing very small embryonic-like stem cellsSerum FSH (a) and estradiol E (b) concentrations after rat’s scarification. The significant differences against chemo-ablated group indicated by a “*” for p < 0.05 and a “**” for p < 0.01. Data are shown as mean ± S.E.M, n = 7Back to article page
