Despite many reports describing functional cell differentiation from pluripotent stem cells (PSCs), for over decades, researchers have failed to generate a complex vascularised organ as an alternative to living/cadaveric organ transplantation. To hurdle this, we focused on the most primitive process of organogenesis. By recapitulating endothelial and mesenchymal interactions during bud development, three-dimensional liver buds(iPSC-LB)were successfully created from iPSCs, resembling in vivo liver buds. Formation of functional vasculatures stimulated the maturation of iPSC-LB into adult liver-like tissues with human specific-functions in vivo. We here propose a new paradigm of(re)generative medicine through the in vitro-derived bud transplant.
