Identification of adipose-derived stem cells (ASCs) and schematic of the experimental design. a Primary ASCs grew in clusters and had a rounded spindle-like shape. b ASCs at passage 2 could differentiate into adipocytes, and the visual field in photographs was filled with red lipid droplets stained with Oil Red O solution. c ASCs differentiated into osteocytes formed calcium nodules with burrs, which were stained red by Alizarin Red solution. d In cartilage pellets, many cartilage lacunae were found, and the glycosaminoglycans around the chondrocytes were stained purple-blue by Toluidine Blue O solution. e Flow cytometry showed that more than 98% of ASCs were immunopositive for the MSC markers CD29, CD44, and CD90, while less than 6% of ASCs were immunopositive for the hematopoietic stem cell markers CD34, CD45, and CD86. f Schematic showing the experimental groups and induction methods. bFGF, basic fibroblast growth factor; β-ME, β-mercaptoethanol; dASC, differentiated ASC; DMEM, Dulbecco’s modified Eagle’s medium; FBS, fetal bovine serum; PDGF, platelet-derived growth factor; SC, Schwann cell; uASC, undifferentiated ASC
