Fig 1. Kinetics of the c-kit⁺ stem/progenitor cells in peripheral blood after oxygenation.

Flow cytometry analysis was used to determine the number of circulating c-kit⁺ stem/progenitor cells, and the data at each time point were derived from between 6 and 10 mice. Oxygenation for 5 minutes (open bar, n = 9–10 at each time point); Oxygenation for 20 minutes (solid bar, n = 6–8 at each time point). * P < 0.01 vs. Control (n = 9).
