Cell Uptake and Validation of Novel PECs for Biomedical Applications
Figure 5
CLSM images of polyelectrolyte complex (PECs) intracellular uptake by (a) human normal fibroblast cells (BJ) and (b) human cervix carcinoma cell line (HeLa). In blue DAPI fluorescence of nuclei. In green FITC fluorescence of PECs. Each confocal image reports the corresponding -stack optical sections (1, 2) to confirm the PECs internalization. Scale bar: 50 μm (a) and 25 μm (b).
