The mouse "tool box" for meiotic studies.

Besides availability, there are numerous advantages to using mice for meiotic studies: (1) techniques exist for enriching the population of spermatocytes at particular meiotic stages; (2) spermatogenesis in mice is highly synchronized and testis sections afford a highly accurate method of staging meiotic events; (3) knock-out mice provide a rich source of meiotic mutants. Coupled with antibody localization techniques these tools, singularly and in combination, provide multiple means of temporally and physically dissecting meiosis.
