Comparison of intracytoplasmic sperm injection for inbred and hybrid mice.

abstract：:Transcription factors inhibit or assist RNA polymerases in the initiation and maintenance of transcription; however, the cell specific expression and roles of transcription factors within bovine ovarian follicles during development are unknown. The aim of present study was to determine if the expression of transcripti...
