Cellular uptake and nuclear accumulation of cfCh and their prevention by chromatin neutralizing/degrading agents. (a) Representative laser scanning confocal microscopy images showing nuclear uptake of numerous fluorescent particles by NIH3T3 cells released from dead Jurkat cells pre-labeled with BrdU at 6 h. The uptake of cfCh is prevented by concurrent treatment with CNPs, DNase I and R-Cu. Few nuclear fluorescent signals are seen when live Jurkat cells were used. (b) Quantitative analysis of mean fluorescence intensity (MFI) of images given in a. Fifty nuclei were analyzed for quantifying MFI. Data were analyzed by Student’s t-test. ****P=0.0001. J, Jurkat cells.
