Fig. 5.

Effect of synthetic peptides on nonconfluent proliferating hASMCs. First column, hASMCs stained with anti-SMM; second column, stained with MM19; third column, merged. Row labels indicate treatments. PBS, control not permeabilized, exposed to PBS; 10S buffer, α-toxin–permeabilized exposed to 10S buffer; 10S Buffer + Peptide A or scrambled peptide, exposed to 30 μM Peptide A or scrambled peptide, in 10S buffer. Bright particles are cell debris. All images were taken on a confocal microscope, 63× or 100×. (All scale bars, 10 μm.)
