Frequency of Proliferating Cells After Exposing In Vitro Neural Progenitors From the SVZ to ¹³⁷Cs γ Rays.

In vitro: Total EdU+ cells
Treatment group	Total EdU+ cells
0 Gy	56.65 ± 2.03%
0.5 Gy	43.35 ± 3.71%
8 Gy	32.84 ± 3.39%*

Note. SVZ = subventricular zone; NSPs = neural stem/progenitor cells; EdU = ethynyl deoxyuridine; ANOVA = analysis of variance. A single cell suspension of NSPs was exposed to γ rays at 0, 0.5, and 8 Gy. Prior to harvest, cells were incubated with 10 µM EdU overnight and then the cells were analyzed by flow cytometry and processed using Click-It chemistry for EdU. Data are averaged from three separate experiments. A *p < .05 by ANOVA followed by Dunnett’s multiple comparisons test compared with 0 Gy.
