ABSTRACT
Objective To induce adipose-derived stem cells (ADSCs) to differentiate into intermediate mesoderm (IM)-like cells ,with IM-like cells for recellularizing kidney scaffolds,and then to obtain a tissue-engineering kidney with renal structures and functions through co-culture.Methods After inguinal fat pads of Wistar rats were surgically harvested,the primary ADSCs were isolated,induced,and cultured for stem cell identification. ADSCs were inducted to differentiate into IM-like cells by adding glycogen synthase kinase-3 inhibitor (CHIR99021) and fibroblast growth factor 9 (FGF9) at different stages. Seven days later,the IM-like cells were identified. The induced IM-like cells and well-prepared kidney decellularized scaffolds were co-cultured for 10 days to obtain recellularized tissue-engineered kidneys and their differentiation was identified.Results The ADSCs harvested had osteogenic and adipogenic abilities and could express the stem cell surface markers. After 7 days of induction,the positive expressions of odd-skipped related 1 and paired-box 2 were observed in IM-like cells by immunofluorescence technique. After 10 days of co-culture with kidney decellularized scaffolds,the positive expressions of Wilms'tumor 1,GATA-binding protein-3,and E-cadherin were observed by immunofluorescence technique.Conclusion ADSCs can be induced into IM-like cells,and renal cell differentiation can be observed through combining the induced IM-like cells with kidney decellularized scaffolds.
