Figure S2. Representative images of hADSc after differentiation. a, b Representative images of hADSc with Alcian Blue staining and Toluidine Blue staining, respectively, indicating chondrogenic differentiation. c Representative images of hADSc with Alizarin Red staining, indicating osteogenic differentiation. d Representative images of hADSc with Oil Red O staining, indicating adipogenic differentiation. All the pictures were magnified 100 times by microscope. (JPG 3076 kb
