Figure 2: Characterization of the ECM components of decellularized pulp. Immunofluorescent staining showed that ECM proteins, Col-IV, laminin, fibronectin, intergrin β1, and vimentin were retained in the decellularized pulp, which was similar to the native pulp, except vimentin, which was decreased in decellularized pulp. Sections were counterstained with DAPI (blue). , scale bars: 100 μm.
