From: In vivo and in vitro toxicity evaluation of liposome-encapsulated sirolimus
TUNEL assay with ARPE-19 cells exposed to liposome-encapsulated sirolimus (LES) (identified by yellow boxes) and liposomes alone (identified by red boxes) in different doses (62.5 µg/mL, 125 µg/mL and 250 µg/mL). The images outlined with dashed white boxes show the control, the BSS/control (d1–2) and the DMSO (dimethyl sulfoxide) positive control (h1–2). Scale bars = 200 μm
