PCL/MD nanocarrier uptake and internalization enhances bioavailability of encapsulated molecule.

Notes: (A) Flow cytometry histograms of LNCaP, DU145, and PC3 after 2 hours of treatment with 25 μg/mL of fluorescent-labeled PCL/MD nanocarrier (red), free fluorescent dye (yellow), and untreated cell line (blue) and medium in which an equivalent amount of nanocarrier has been previously suspended (black). (B) Cellular internalization of PCL/MD in LNCaP, DU145, and PC3. Fluorescence microscopic images of uptake taken (after 2 hours) with a Zeiss ApoTome microscope with an Axiom Cam version 4.5 imaging system at 40× magnification.

Abbreviations: PCL, polycaprolactone; MD, maltodextrin.
