Effect of chemical surface composition on HUVEC proliferation. Proliferation of HUVEC on plasma untreated and treated PCL polymers determined by MTT assay. Student’s -test was used to check the statistical significance. Statistically significant at for 3 hours compared with control. Statistically significant at for 3 hours compared with control. Statistically significant at for 24 hours compared between O2 and SO2 plasma treated samples. Statistically significant at for 24 hours compared with control and/or between NH3 and SO2 treated samples. Mean values (±SE) for the respective duplicates are given.
