Research topics 【 display / non-display

  • We are working on in vitro generation of ocular tissues using pluripotent stem cells (iPS, ES cells) and successfully generated 2-dimensional "whole eye organoids" from human pluripotent stem cells (Nature 2016). Furthermore, we performed its application to ocular regenerative medicine such as a corneal regeneration.
    Ophthalmology-related, Cell biology-related, Developmental biology-related, Molecular biology-related

  • We have been working on the regulation mechanism of cell development and differentiation by ECM-mediated signalling. Particularly focus on laminin isoforms and YAP-mediated signal transduction.
