In vitro and in vivo effects of insulin-producing cells generated by xeno-antigen free 3D culture with RCP piece

Abstract To establish widespread cell therapy for type 1 diabetes mellitus, we aimed to develop an effective protocol for generating insulin-producing cells (IPCs) from adipose-derived stem cells (ADSCs). We established a 3D culture using a human recombinant peptide (RCP) petaloid μ-piece with xeno-...
