Fig. 4. Dsg3^dim population of palm keratinocytes survived better than Dsg3^bri population in long-term culture. (A) Phase-contrast images (a,b; arrows delineate margin of colony) of different clone types in Dsg3^dim and Dsg3^bri at passage 2. Large colonies are observed in the Dsg3^dim (a) but not the Dsg3^bri population, in which almost all the colonies are abortive (b). (B) Assessment of the frequency of abortive colonies in Dsg3^dim and Dsg3^bri at passage 2. Of 96 colonies in Dsg3^dim only 59 are abortive colonies, however, 32 out of 33 are abortive colonies in Dsg3^bri (P<0.05). Scale bar: (in A) 50 µm.
