Figure 5. Cell viability assay by MTT. After 6 to 12 days transfection with Skp2 siRNA, cell viability was significantly decreased in cultured hPFC cells compared with vehicle control and blank control epsecially on the 6th day after transfection. *p<0.01 versus vehicle and blank control; **p<0.05 versus vehicle and blank control.
