The in vitro growth inhibition of the MCF-7 cells after transfection with DNA/ORMOSILNs complexes. The number of adherent cells was determined at each time point. Each point indicates the mean ± SD of values obtained from the assay of cells from six replicate microtiter plate wells. *p < 0.05, compared with the in vitro growth inhibition of the control
