Figure 6.
An average of 9,000 cells was counted for each raft. BrdU-positive cells were counted in the basal and suprabasal layers and the labeling index calculated as a percent of the total cell population. No significant change between controls (A,C) and rafts (B,D) treated with polyamide 25 was noted for basal cell labeling. For suprabasal labeling, a significant decrease was noted relative to controls for rafts treated with polyamide 25: * p=0.002; ** p=0.0000001. Basal cell labeling was not significantly affected (E).
