Figure 4. Cell proliferation assay by Brdu. Expression of BrdU decreased in pKLF6 cDNA transfectant cells (C) compared with rLEC of the vehicle control (A) and blank control (B). Cell counting showed that Brdu positive cells in rLEC transfected with pKLF6 cDNA significantly decreased compared with control cells (p<0.01 versus vehicle and blank control, D).
