When follicles had been Evista pontent inhibitor subjected to 1.5?M NaCl, just 2% from the follicles were viable, whereas 87% from the follicles were viable after contact with 4.0?M EG. Concerning exposure time, the best percentage of practical follicles was obtained when follicles were exposed for 10?min to 1 1.0?M EG?+?0.5?M sucrose; exposure for 60 s to 4.0?M EG?+?0.5?M sucrose also maintained high percentage viability in follicles. Slow cooling in the presence of 1.0?M EG?+?0.5?M sucrose (75%) or rapid Evista pontent inhibitor cooling in the presence of 4.0?M EG?+?0.5?M sucrose (71%) resulted in a significantly higher proportion of viable follicles than all other treatments (at 40?m Open in a separate window Fig.?2 Viability based on trypan blue staining of isolated caprine early-staged follicles exposed to NaCl (experiment 1; ((((((((non-viable cells). a Positive control, Triton X-100 treated secondary follicle. b Viable secondary follicle. c Non-viable secondary follicle. 50?m (JPG 240?kb) Supplementary Figure 2(295K, jpg)Viability of goat early-staged follicles based on staining with Hoechst (all nuclei) and ethidium homodimer-1 (nuclei from dead cells). a, b Representative image of a viable primordial follicle. c, d Representative image of two non-viable primordial follicles. Follicle contains a viable oocyte, whereas fewer than 90% of granulosa cells are viable. Follicle contains three oocytes of which one has deteriorated, and fewer than 90% of granulosa cells are viable (oocytes). Note that polyovular healthy early-staged (primordial, primary, and secondary) follicles are commonly observed in goats (Lucci et al.
