The Effect of Gamma Irradiation on the Biological Properties of Intervertebral Disc Allografts: In Vitro and In Vivo Studies in a Beagle Model
Figure 1
Disc cell viability detected by fluorescence microscope (200 times magnification).
AF-annulus fibrosus, NP- nucleus pulposus. Under fluorescence microscope, the living cells were shown in green and the dead cells in orange. The cell survival rate = the number of green-stained cells/the total number of stained cells.
