Outline Activities
Education: The lectures for students that I provide are (1) Basic Zoology, (2) Basic Biological Experiment, (3) Developmental Biology, (4) Experiments for Zoology and Development, (5) Development of Vertebrates, (6) Special lecture of Zoology, (7) Special studies of Zoology I and II, (8)Practice of Zoology I and II, (9) The Applied Genetics and Pest Management I. Through these lectures, I intend to assist students in forming the scientific basis of Biology, Developmental Biology and Zoology, in particular for mammalians. The students could understand the molecular mechanisms responsible for development and differentiation of life and cell.
Research: By using techniques of morphology, molecular biology and biochemistry, I intend to isolate genes and proteins involved in germ cell differentiation in testis as well as sperm-egg interaction, by which I wish to elucidate the molecular mechanisms regulating spermatogenesis and fertilization.

Research Interests
  • (1) Studies of differentiation, molecular structure, and maturation of spermatozoa
    (2) Fertilization

    2000.04~2020.03Differentiation of male germ cells is a complicated process beginning with the proliferation of diploid spermatogonia and terminating with the production of morphologically distinct haploid spermatozoa. During a post-meiotic stage, round haploid spermatids undergo the drastic morphological changes, such as acrosome formation, nuclear condensation, flagellum formation, mitochondrial sheath construction and extrusion of residual cytoplasm through which round spermatids are differentiated into mature spermatozoa. To investigate the molecular mechanisms regulating the drastic morphological changes from round spermatids to spermatozoa, we used differential display in combination with cDNA cloning technique to isolate genes that are predominantly expressed in haploid spermatids. So far, we isolated novel genes, named spergen-1, spergen-2, spergen-3, spetex-1, and spetex-2. Expression, localization and their physiological functions are investigated. In addition, we performed Yeast Two-hybrid approach to isolate molecules interacting with these molecules..
