  • I am studying on the development and reproduction of echinoids. The sea urchin egg has a polarity, many kind of cells forming skeleton, muscle and digestive tract appear from the one side of egg (vegetal pole). It is well known that the cell line of skeletogenesis is a first group whose cell fate is decided at first. We have examined the developmental potential of each part in vegetal side and shown that most of all vegetal side has a potential of skeletogenesis in the culture after a separation to a small volume. It is considered that the skeletogenic potential is suppressed and each part is regulated to the normal cell fate in embryogenesis.
    Some of metal ions and chemicals have an effect on the morphogenesis of digestive tract. Exogastrula induced by Estrogen or Li, in which the digestive tract project to the outside, is examined. The roles of steroid hormones, such as estrogens, are also examined on the yolk protein production and gametogenesis.

Educational Pursuits 【 display / non-display 】

  • I teach the lectures and the experimental courses on the systematic zoology and developmental biology. In the lecture of systematic zoology, the characters of body plan of each phylum are expounded in the order of phylogeny. In the lecture of developmental biology, the morphological changes from a fertilized egg to the complete animal body are explained and the controlling mechanism by a interaction between tissues and cells and a signaling pathway of molecules and genes are expounded. Each laboratory courses are in marine laboratory (Marine and Coastal Research Center, Tateyama). In the laboratory course of systematic zoology, students go to sea shore to collect animals and take a boat to collect marine plankton by net. They understand the real animal diversity by examining animals collected by themselves. In the laboratory course of developmental biology, embryo manipulation and immunostaining on the fertilization and early development are performed. I also teach a laboratory course of diving for the observation and research of marine animals.

Future Research Plans, Research Prospects, and Joint Research Potential 【 display / non-display 】

  • The developmental system on the autonomous ability is investigated by cell culture system of sea urchin. The goal is how to explain such autonomous ability from gene regulation network. Ancient developmental process is remained in the modern species and it is expected to help the understanding the evolution of animal morphogenesis. Also, the experimental system using sea urchin will be provide useful assay system of environmental stress such as chemicals and gravity. The research on the reproduction is directed to the improvement of animal supply as the experimental material.
