Effect of VCAM-1 siRNA4 on SMC proliferation 24 and 48 h after treatment. Seventy percent confluent cells were transfected with siRNA4 or control siRNA targeting VCAM-1 for up to 48 h before the MTT cell growth assay was run. Values are means ± S.D. of four separate experiments. *P < 0.05 vs. control.
