Abstract (original English)

To establish a recellularization kidney model by using adipose tissue-derived stem cells (ADSCs) as seeding cells and to investigate the growth and differentiation of ADSCs in decellularized kidney scaffolds. ADSCs were isolated using a modified method and then identified using flow cytometry analysis. Osteogenesis and adipogenesis differentiation were performed. Rat kidneys were decellularized using 0.5% sodium dodecyl sulfate. Immunofluorescence, immunohistochemistry, and scanning electron microscope were conducted to examine the scaffold microstructure. The decellularized kidney scaffold was seeded with ADSCs antegrade through the artery or retrograde through the ureter and cultured for 5-10 days. Hematoxylin and eosin staining, immunofluorescence, and immunohistochemistry were applied to assess growth and differentiation of seeding cells within the scaffold. ADSCs populated within the glomerular, vascular, and tubular area of kidney scaffolds. Cells differentiated toward endothelial or tubular cells. Stromal cell-derived factor 1 promoted cell attachment in the scaffold. These findings suggest that ADSCs can be used as an additional new source of seeding cells within decellularized kidney scaffold. This combination may offer an alternative to donor kidney transplant. In this way, autologous ADSCs can be utilized as seeding cells in cell-scaffold kidney regeneration for furt
