Figure 6From: Mechanistic studies of Gemcitabine-loaded nanoplatforms in resistant pancreatic cancer cells Ultracharacterization studies of Gemcitabine, PLGem and GemPo in PANC1 cells. Cells were left (A) untreated, or treated with (B) free Gemcitabine, (C) GemPo or (D) PLGem for 1 day and then processed for TEM analysis. (n) indicates nucleus localization. Full and doted arrows highlight cytosolic and uptake pathways, respectively.Back to article page
