Figure 2. Morphological study and graft recovery rate of fresh and frozen-thawed grafted testis tissue in the epididymal fat region. A: Fresh grafted testis tissue from a neonate (arrow) in the epididymal fat of an adult mouse (8 weeks after graft). B: Grafted frozen-thawed neonatal testis tissue (arrow) in mature mouse epididymal fat (8 weeks after graft). C: At eight weeks post-transplantation, there was no significant difference between the percentage of recovered grafts harvested from fresh and frozen-thawed tissues. (F G: Fresh grafted; F-T G: Frozen-thawed). α, β: Significant difference compared to other groups. Scale bar: 10mm.
