Figure 7.

Effect of hydrogen on CD133⁺ progenitors. Mice were treated as described in Fig. 1 (n = 4 in each group). Lung samples were harvested for CD133⁺ cell staining (A) and counting (B). Blood samples were extracted and CD133⁺ cells were counted (C). (D) Cultured CD133⁺ progenitors were stained with hydroxyphenyl fluorescein solution and DAPI. Scale bar, 50 μm. Data shown are mean ± SEM. ns, not significant.
