Resumption of ovarian development after injection of bovine insulin. (A) Ovaries in wild-type females. (B) Ovaries in cold storage females injected with insulin recovered development and showed uniform ovarioles with matured follicles comparable to the counter parts in wild-type females. (C) Ovaries in cold storage females treated with BSA remained unmatured. (D) Primary follicle (1 fol) and secondary follicle (2 fol) length in cold storage females increased dramatically after treatment of insulin hormone. Scale bar is 1 mm. Mean ± SE with the same letters are significantly different at P = 0.05, n = 9, ANOVA.
