Figure 7. Differentiation potential of spheres derived from EGFP+ and EGFP− cells from craniofacial and trunk regions.
(A) Broad range of differentiation potential in spheres derived from craniofacial EGFP+ cells. All groups of spheres differentiated into neurons, glial cells, myofibroblasts and adipocytes. Chondrocytes were differentiated from only spheres derived from craniofacial EGFP+ cells and trunk EGFP− cells. Osteocytes were differentiated from all groups of spheres except for spheres derived from trunk EGFP+ cells. (B–F) Spheres derived from trunk EGFP+ cells showed peripheral neuronal lineages. Quantitative analyses of the potential for differentiation into neurons (B), oligodendrocytes (C), glial cells including Schwann cells (D), and myofibroblasts (E) by counting the number of cells positive for specific markers. (F) Quantification of adipocyte differentiation by relative fluorescence units (RFU). Excitation and emission of Adipo Red-stained cells was measured at 485 and 535 nm, respectively. Trunk EGFP− cells showed the highest differentiation potential among the four groups.
