Characterization of decellularized extracellular matrix (dECM). Morphology, mineralization, and alkaline phosphatase enzymatic activity (ALP) were examined (A). Ultrastructure of dECM was observed using scanning electron microscopic analysis (B). Fibronectin and type I-collagen were determined using immunofluorescence staining (C). The genetic component was stained using DAPI (C). Glycosaminoglycans deposition was detected by Alcian Blue staining (D) Chemical composition of dECM was examined using energy-dispersive X-ray spectrometry (E). dECM-N; decellularized extracellular matrix derived from maintaining cells in normal medium, dECM-OM; decellularized extracellular matrix derived from maintaining cells in osteogenic medium.
