First vascularized model of stem cell islet cells [caption id="attachment_11877" align="aligncenter" width="1024"] Engineered vasculature induces functional maturation of pluripotent stem cell-derived islet organoidsResearchers have devised the right conditions to grow vascularized stem cell islets. The image shows vasculature (red) tightly wrapped around insulin-producing cells (green) in the islets (blue). ©…..
