Figure 7: In vitro inhibition of K562 and HL60 proliferation by sFLT-1. K562 and HL60 cells transfected with psFLT-1 subjected to MTS analysis. psFLT-1 transfected cells versus pGFP transfected or untreated cells. Each data point is presented as mean ± SEM. The value greater than 0.05 (0.349 and 0.769, resp., in K562 and HL60 treated cells) showed no significant inhibitory effect in treated cells compared with control groups.
