Cogels of Hyaluronic Acid and Acellular Matrix for Cultivation of Adipose-Derived Stem Cells: Potential Application for Vocal Fold Tissue Engineering

Figure 1

Characterization of isolated hADSCs. (a) Isolated hADSCs were shown to be positive for CD29 (98.9%), CD105 (99.4%), and CD90 (99.7%), while they have been shown to be negative for CD45 (0.1%), CD34 (16.4%), and CD31 (0.1%) in cell population. (b) hADSCs were shown to be in spindle-like shape at passage 3. Scale bar = 50 μm. (c) Osteogenesis of hADSCs was assessed by von Kossa method. (d) Adipogenesis of hADSCs was assessed by Oil Red-O staining.
