[Retracted] The Effects of Cytokines in Adipose Stem Cell-Conditioned Medium on the Migration and Proliferation of Skin Fibroblasts In Vitro

Figure 1

Isolation and identification of human fibroblasts and ASCs in vitro. Fibroblasts were spindle-shaped (a) and positive for immunofluorescence staining of vimentin (b), while negative for cytokeratin 15 (c). ASCs were identified by flow cytometry of mesenchymal stem cells markers (d) and multiple differentiations. Adipogenesis of ASCs was confirmed by Oil-Red-O staining (e) and gene expressions of PPAR-γ (g). Osteogenesis was confirmed by alizarin red staining (f) and gene expression of Runx2 (h).
