Figure 5. In vitro liposomal drug uptake by T24 cells. Cells were incubated for 3 h in the presence of 10 µmol/L Dox and/or 7 µmol/L MLP in various liposomal formulations. A: uptake of MLP; B: uptake of Dox, including free Dox as control. Note that low and comparable levels of the liposomal drugs drug are taken up by tumor cells
