Research Abstract

Improve spectacularly of in vitro maturation (IVM) of an immature oocyte which makes the core of in vitro culture system of oocyte is aimed, it focused on localization, morphology and function of the microtubules (e.g. gap junction, nuclear membrane, chromosome, endoplasmic reticulum, spindle, mitochondria, cortical granule) of an immature oocyte, and identified the control agent. Furthermore, the chemical substance which controls expression of a control agent artificially was searched.
