Research Summary

Atsuo  Ogura(D.V.M., Ph.D.)

Our goal is to understand how new life is established at fertilization, how the germline genomes are established during development, and how the resultant embryonic genomes are programmed to contribute to two developmental lineages (the embryonic and placental lineages) in the mammalian life cycle. To this end, we reconstruct special embryos using reproductive engineering techniques including microinsemination (sperm or spermatid injection), nuclear transfer cloning and establishment of new stem cell lines, and undertake systematic and comparable analyses. This strategy may provide us with the opportunity to solve the important questions above, which cannot be achieved by the conventional experimental methods.
