Research Abstract |
Nuclear reprogramming means that either functional or molecular changes to cells undergoing fate changes, and the mechanism elucidation would deliver great advance not only for the basics of biological systems also more applicable field such as medicine and drug development. In this study, mouse zygotes are focused to be elucidated reprogramming. In early stage of the mammalian preimplantation development, most dramatic epigenetic change is observed the pronuclear formation through their fusion process. Female and male pronuclear materials were collected by micromanipulation technique and were done by the global transcriptional expression analysis using linear amplified RNAs. Gene cluster analysis in conjunction with reprogramming in silico was performed. It was able to extract a convincing gene mainly on a gene in conjunction with the chromatin reprogramming.
