Since the results implied the possible role of miPS-Huh7cm and miPS-huh7cmP1 cells in tumour angiogenesis, the expression of vasculogenesis-associated factors such as VEGF-A, VE-cadherin and platelet-endothelial cell adhesion molecule-1 (CD31) were evaluated in both cells.23 As a result, both cells were found to express VEGF-A but no significant difference was observed between the expression levels in those cells in the adhesive condition, which contained both differentiated and undifferentiated cells, and that in undifferentiated population limited by puromycin. The gene discussed is CDH5; the disease is neoplasm.
