The expression of surface marker CD105 in hADSCs in HA, HA-Col, and HA-DCM hydrogel. The immunofluorescence staining showed CD105 (green) positive cells in HA, HA-Col, and HA-DCM hydrogel. Nuclei were stained by DAPI (blue). Scale bar = 50 μm. The analysis through ImageJ software indicated that cells in HA-DCM hydrogel expressed higher CD105 than cells in HA-Col and HA hydrogel significantly at day 7. indicated .
