| Research Abstract |
We tried the elucidation for the global image of the meiosis pause mechanism seen in oocyte maturation process based on the previous results of research. The upstream factor was searched based on the data of a DNA microarray, and it was shown clearly that C-Type natriuretic peptide and adrenomedullin lead to identification of an upstream factor. Furthermore, we also tackled improvement of IVM and it was shown clearly that fertilizing capacity and the developmental competence after fertilization go up by in vitro oocyte maturation for a definite period of time by cAMP or a cAMP potentiation factor.
