Proliferation of SP cells in the ischemic kidney after IRI. ((a) and (b)) Proliferation of the SP and non-SP cells in the ischemic (a) and nonischemic (b) kidney after IRI. Fractions of S-G₂M kidney SP and non-SP in sham-operated and IRI animals were obtained by propidium iodide staining. *P < 0.05 versus sham. (c) Effect of hypoxia and SD alone or a combination of both on cell proliferation in vitro. The cells without both hypoxia and SD stimulation were used as controls. *P < 0.05 versus control; ^† P < 0.05 versus hypoxia; ^‡ P < 0.05 versus SD; ^# P < 0.05 versus SP.
