Fig. 4From: CD44-specific short peptide A6 boosts cellular uptake and anticancer efficacy of PEGylated liposomal doxorubicin in vitro and in vivoIn vitro cellular uptake A6-PLD, PLD, and C26 cells (A) and NIH-3T3 cells (B) at 37 ℃. Green line: control cells, black line: cells incubated with PLD for one hour at 37 ℃, Blue line: cells incubated with A6-PLD for one hour at 37 ℃, red line: cells pre-treated with free A6 and then incubated with A6-PLD for one hour at 37 ℃Back to article page
