Reconstitution of Kidney Side Population Cells after Ischemia-Reperfusion Injury by Self-Proliferation and Bone Marrow-Derived Cell Homing

Depletion of SP cells in the ischemic kidney after IRI. (a) Fluorescence-activated cell sorting isolation of SP and non-SP cells in the left kidney from normal animals and IRI animals. Hoechst low SP cells are identified by the R3 area and demonstrate an a decrease in kidney SP cells within 1 day after IRI. (b) The histological score of kidney (HSK) in kidneys from sham-operated and IRI-mice was calculated. versus sham; versus IRI 1 d. ((c) and (d)) The SP cells in left (c) and right (d) kidneys from sham-operated (white bars) and IRI (black bars) animals. versus sham; versus IRI 1 d. (e) In vitro apoptosis analysis of kidney SP and non-SP cells in basal conditions and after simulated ischemia. Cultured kidney SP and non-SP cells were subjected to hypoxia and SD alone or in combination for 6 h. Bar graph described from the FACS-based Annexin V/propidium iodide apoptosis assay. The cells without both hypoxia and SD stimulation were used as controls. versus control; versus hypoxia; versus SD; versus non-SP.
