Selective uptake of A415-PCL by ATRA-treated SH-SY5Y cells, the selectivity being dependent on incubation time. (A) ATRA-treated SH-SY5Y cells incubated with A415-PCL for 20 minutes. (B) ATRA-treated SH-SY5Y cells incubated with Scr-A415-PCL for 20 minutes. (C) ATRA-treated SH-SY5Y cells incubated with A415-PCL for 4 hours. (D) ATRA-treated SH-SY5Y cells incubated with Scr-A415-PCL for 4 hours.
Note: Bar corresponds to100 μm.
Abbreviations: ATRA, all-trans-retinoic acid; PCL, peptide-conjugated liposomes.
