Research Description:

My research focuses on cellular and molecular properties of the gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus and the mechanism of puberty onset. The absence of GnRH neurons or an abnormality in the control system results in diseases, such as idiopathic hypogonadotropic hypogonadism (IHH). Although we have an excellent non-human primate model with a primary cell culture system derived from embryonic monkey olfactory placode in vitro, and a measurement of GnRH release in vivo, generation of GnRH neurons from human ESCs and iPSCs provides a tool for studying the mechanism of GnRH pulse-generation, the rapid actions of steroid hormones, and epigenetic control of neuronal maturation in human GnRH neurons. Accordingly, we will first generate GnRH neurons and then investigate the cellular and molecular properties of GnRH neurons with multidisciplinary approaches. It is my hope that generation of GnRH neurons from human will provide a potential treatment tool for IHH patients.
