[Others] Research: In the development of vertebrates, the pharyngeal region of embryos gives rise to various organs that are important for maintaining life. For example, several endocrine organs (e.g., the thyroid gland and ultimobranchial gland) and an immune tissue, the thymic epithelium, are derived from this region, and the gill also develops in fish and amphibians. The goal of my research is to understand the molecular mechanisms underlying the morphogenesis of the pharyngeal region, which leads to an artificial generation of pharyngeal derivatives such as the above organs, to an analysis of the effects of environmental chemicals on the developmental processes, and further to an explanation of the mechanisms for causing the diversity and evolution of vertebrates. I aim to discover essential phenomena common to all classes of vertebrates, exploiting the characteristics of animals other than mammals. Joint projects have been conducted with Prof. Shigeyasu Tanaka.
