Fig. 1. Confocal microscopy images to demonstrate bystander uptake by NIH3T3 cells of dually labeled cfCh released from irradiated dying Jurkat cells that had been labeled in their DNA with BrdU (red) and histones by CellLight® Histone 2B-GFP (green).

A Dually labeled Jurkat cells. B NIH3T3 cells that had been co-cultivated with irradiated (15 Gy) dually labeled Jurkat cells for 24 h. C NIH3T3 cells that had been co-cultivated with un-irradiated dually labeled Jurkat cells for 24 h
