Purpose:
- To establish a straightforward and efficient protocol for isolating spermatids from adult mouse testes.
- To optimize the use of enzymatic digestion and discontinuous Percoll gradient centrifugation for cell separation.
Summary:
- A modified discontinuous Percoll gradient centrifugation method was employed following enzymatic digestion of mouse testes.
- The 22% Percoll fraction yielded a high concentration of spermatids (mean 86.7%) with over 85.5% viability.
- Morphological analysis and flow cytometry confirmed spermatid purity, while Eosin Y exclusion assessed cell viability.
Impact:
