Fig. 3From: Lycorine transfersomes modified with cell-penetrating peptides for topical treatment of cutaneous squamous cell carcinomaCellular uptake of transfersomes on human skin squamous cell carcinoma (SCL-1) cells. A Fluorescence microscopy images of uptake of free C6, C6@STFs, C6@DTFs, C6@STFs-CPP, and C6@DTFs-CPP by SCL-1 cells. Scale bar: 500 µm; B quantitative analysis of the uptake of various C6 formulations using flow cytometry; C mean fluorescence intensity treated with various C6 formulations for 1 h; control represents untreated cells. Data are expressed as the mean ± SD (n = 3). *p < 0.05, **p < 0.01, and ***p < 0.001Back to article page
