The fluorescence microscopy images showing cellular uptake of HCPT-NSps and HCPT injections by HepG2 cells.
Notes: Cellular uptake of (A) HCPT-NSps and (B) HCPT injections. HepG2 cells were incubated with HCPT-NSps and HCPT injections, at 37°C for 4 h. HCPT-NSps displayed more cellular uptake than HCPT injections at all the three concentrations.
Abbreviations: HCPT, 10-hydroxycamptothecin; NSps, nanosuspensions.
