Expression profiling of purified murine epididymal spermatozoa and murine leukocytes.
A study utilizing next-generation sequencing provided a comprehensive expression profile of murine spermatozoa, revealing the transcriptional landscape of mature sperm isolated from the corpus and cauda epididymides of C57BL/6 mice. By analyzing RNA content, we identified a distinct set of retained transcripts, including those encoding sperm-specific ion channels, as well as transcripts associated with sperm motility, capacitation, and the acrosome reaction. In addition to spermatozoa, the study also reported the transcriptional profiling of murine leukocytes, providing comparative insights into cell-type-specific gene expression. This study advances our understanding of sperm transcriptomics and its implications for male fertility Overall design: RNA-seq profiling of C57BL/6 murine spermatozoa and blood leukocytes
