My DreamClarifying the roles of corticosteroids in oogenesis and ovarian physiology
ThemeInvestigating roles of corticosteroids and their regulatory mechanisms in oogenesis, folliculogenesis leading to the ovulation, and embryo development, and applying the kowledge to inprove efficiency of in vitro production of embryo.

I was born in Tokyo. After compleating B.Sc.and M.Sc.in Obihiro, I spent 10 years in Australia and Scotland. I am an OB of Hekiun Domitory and Kyudo club. I live in a countryside of Nakasatsunai village with my wife and a cat. I am a member of Nakasatsunai Riding Club but not very good at riding.

Corticosteroids (glucocorticoid and mineralocorticoid) produced by the adrenal cortex are crucial for keeping homeostasis. The ovary is exposed to the circulating corticosteroids throughout life yet little is known about the physiological effects of the steroids on the ovarian function. We have demonstrated that ovaries of various species such as rats, human and cattle express receptors and metabolizing enzymes for these corticosteroids and they are dramatically regulated during folliculogenesis and ovulation. These results strongly imply corticosteroids play important roles in the ovarian physiology. We are currently investigating roles of corticosteroids in the bovine oogenesis and embryo development. Our aim is to improve quality and efficiency of in vitro production of embryos.
