Figure 2From: Amorphous nanosilica induce endocytosis-dependent ROS generation and DNA damage in human keratinocytes Effect of silica particles on membrane damage. Cellular membrane damage in HaCaT cells after incubation with nSP70 (circles), nSP300 (squares) and mSP1000 (diamonds) for 24 h was evaluated by the LDH release assay. The percentage cellular membrane damage was calculated relative to the negative (medium) controls. Data are presented as means ± SD (n = 3).*P < 0.01 vs same dose of nSP300 and mSP1000.Back to article page
