title: SDF-1α and CXCR4 as therapeutic targets in cardiovascular disease.
abstract: SDF-1α/CXCR4 signaling is important for endogenous processes, including organogenesis and hematopoeisis, as well as in response to tissue injury. The secretion of SDF-1α acts as a chemoattractant to facilitate the homing of circulating CXCR4 positive cells as well as other stem cells to the site of injury for the initiation organ regeneration and repair. In the case of cardiovascular disease, and particularly myocardial infarction, this signaling axis is implicated in many of these processes, and has an additional role in providing trophic support for cells and utilizing paracrine mechanisms to enhance cell survival, promote angiogenesis, and stimulate differentiation. Current research is focused on elucidating these complex events, and so far have produced promising results that have led to the development of cell therapies that can more effectively repair cardiac tissue following ischemic injury than currently used treatments. Despite these advancements, much remains to be discovered so that in the future, new treatments will be better able to regenerate tissue and recover function.
