CXCL12 and ischemia: VEGFa, SDF-1α, and FGF2 factors measured in the present study are responsible for angiogenesis, proliferation, migration, expressions of adhesion protein, and extracellular matrix reconstruction [17, 18, 30, 50–52] and are involved in initiating tissue repair and reperfusion following ischemia [49, 53, 54].
