Relationship between the presence of endogenous nicks and sperm chromatin packaging in maturing and fertilizing mouse spermatozoa.

Abstract

Mammalian spermiogenesis involves the replacement of histones by protamines, resulting in a highly compacted chromatin. Upon fertilization, the reverse process occurs. We have previously shown that the chromomycin A3 (CMA3) fluorochrome represents a useful tool for detecting protamine deficiency in spermatozoa. In this study we investigated CMA3… (More)
