(A) Immunofluorescence analysis on immunomagnetically selected hDPSCs shows the expression of the stemness markers c-Kit, STRO-1 and CD34. Bar: 10 μm. (B) Phase contrast images demonstrate the ability of selected hDPSCs to aggregate in floating three-dimensional spheres, as early as 24 h after cell seeding, and to grow in size through culture time, up to passage 8. On the right, a higher magnification emphasizing the semi-transparent appearance of 3D spheres. Bar: 100 μm.
