Fig. 2From: Structure of preantral follicles, oxidative status and developmental competence of in vitro matured oocytes after ovary storage at 4 °C in the domestic cat modelRepresentative images of tubulin organization of preantral follicles after different times of ovary storage at 4 °C. Tubulin staining of granulosa and stromal cells is progressively reduced with increasing storage time (a-i) and bright spots of tubulin appear in the cytoplasm of follicle enclosed oocyte (d-l, white arrow). Nuclei were stained with Hoechst 33,342 (blue). Scale bar = 20 μm (a, c, e, g, i); 10 μm (b, d, f, h, l)Back to article page
