Fig. 6From: Innovative multi-protectoral approach increases survival rate after vitrification of ovarian tissue and isolated follicles with improved results in comparison with conventional methodHistogram of live and apoptotic follicles distribution in the sheep ovarian cortex after cryopreservation with different protocols. Samples were analyzed by the TUNEL apoptosis detection kit. Histogram illustrates that slow freezing method ensures the better preservation of primordial follicles in the tissue, while vitrification methods 1 and 2.3 showed best results amongst tested vitrification protocolsBack to article page
