Beauty of science: bovine blood-brain barrier

12-04-2013

Bovine blood-brain barrier (BBB) in vitro model 1 h after synchrotron irradiation with a dose of 100 Gy using microbeam radiotherapy (MRT) (microbeam spacing center to center, 411 micrometres, microbeam width, 50 micrometre).

The capillary endothelial cells are imaged with a fluorescence microscope. Nuclei are stained in blue with DAPI fluorescent dye that binds the DNA. Cell membranes are stained in green with anti-ZO1 tight junction protein antibody. The red signal corresponds to DNA double-strand breaks (DSBs) detected with anti-gH2AX antibody under microbeam path.
