Figure 4. Morphometric analysis in colonies generated from human fibroblasts by using a single polycistronic Oct3/4-Klf4-Sox2-c-Myc-GFP expressing viral vector.

(H–L, G) Photograph and parameters of colonies H∼L and G. Graphs shows parameters of each classified colony, including that of iPS cell colony G. The numerical value in the graph indicate the ratio to the maximum value (setting 100 for maximum value) in each parameter. Scale bars = 100 µm.
