In vitro anti-tumor efficacy of various liposomes. (A) The Graphical plot shows the percent tumor cell viability after treatment with various Dox and Erlo loaded liposomes using an in vitro brain tumor model for 24 h. Significant (p < 0.05) differences with (*) plain liposomes, (#) free Dox-Erlo, (‡) Tf-liposomes, (†) TAT-liposomes, and (¥) QLPVM liposomes were observed. Data represented as mean ± SD, (n=4). (B) The fluorescence images show tumor cell death in scaffold after treatment.
