SDF-1α prior to ischaemia improves contractile recovery of rat heart papillary muscle that is isolated and subject to 30 min hypoxia and 2 h reoxygenation. Before hypoxia, the rat papillary muscle was perfused with 1) SDF-1 for 10 min; or 2) AMD3100 for 5 min then AMD3100 plus SDF-1 for 10 min, or 3) AMD3100 alone for 15 min. Control papillary muscle was untreated. Data expressed as mean ± SE. The functional recovery of muscle treated with SDF-1 alone was significantly improved (P < 0.05) (Davidson et al., 2013).
