HMGA2 expression in deciduous pulp. HMGA2 is abundantly expressed in deciduous pulp but only by a subpopulation of cells. A) HMGA2 (red), vimentin (green). B-G are zoomed in areas. C, E, G show co-localization of DAPI staining and HMGA2. A: scale bar 1,000 μm; B, D and F: 50 μm; C, E and G: scale bar 20 μm. DAPI, 4',6-diamidino-2-phenylindole.
