Related Outline

The aim of our research is to understand the events underlying early mammalian development. One of the characteristics of mammalian embryonic development is that embryogenesis proceeds in the oviducts and the uterus of the mother, and the interactions between the embryo and maternal tissue are essential in this process. Another characteristic is the highly regulative potential of embryos. Cells within embryos interact with their environment and establish their own fates and behaviors. We want to provide basic and fundamental information about the specification of the differentiation of cell lineages, embryonic axes, cell behaviors, body shape regulation, and tissue morphology in early mammalian development. We are also interested in the relationship between embryos and their environment, the oviducts and the uterus. And we have been analyzing the changes in the morphology and characteristics of these maternal organs supporting embryonic development.
