Cell transplantation and cardiac repair
sea-maid submitted, created time 1 year 2 months (www.eurekalert.org)
Two separate studies published in the current issue of Cell Transplantation into cardiac repair by cell transplantation have found, respectively, that the best way to deliver autologous bone-marrow mononuclear cells to the heart following a myocardial infarction was via the anterograde intracoronary vein and that bone marrow cell transplants for limb ischemia induced angiogenesis in patients failing therapy and facing amputation. The first study found higher cell retention; the second demonstrated an alternative to amputation.
