Characterization of human zona pellucida glycoproteins.

abstract：:In recent years, advances in imaging probes, cutting-edge microscopy techniques and powerful bioinformatics image analysis have markedly expanded the imaging toolbox available to developmental biologists. Apart from traditional qualitative studies, embryonic development can now be investigated in vivo with improved sp...

abstract：:Sperm are motile cells. Thus, a significant component of the spermatogenic cycle is devoted to the formation of flagellum, a process that must be coordinated to insure proper construction. To document the temporal pattern of flagellar gene expression, we employed real-time PCR to assess changes in accumulation of a co...
