Figure Lengend Snippet: (a) Immunofluorescence staining showing expression of Vimentin (green) and CD105 (red) in DPSC and SHED compared with HaCaT epithelial controls. (b) STRO-1 (green) immunostaining in SHED. Nuclei were counterstained with DAPI (blue). Scale bar = 100μm (c) Representative flow cytometry analyses demonstrating expression of mesenchymal stem cell markers (CD73, CD90, CD105, HLA-ABC) and absence of hematopoietic markers (CD34, CD45). All experiments were perfomed at passage 5 (d) Growth curves comparing cumulative population doublings of DPSC and SHED derived from four independent donors across serial passages. SHED displayed enhanced proliferative capacity and reduced donor-to-donor variability.
