Abstract
- Abstract: Stem cell capability enhanced with cytokine administration is a promising treatment for myocardial infarction. Bone marrow stem cells (BMSCs) were isolated from C57BL/6 mice (8–12 weeks old) expressing GFP and characterized with c-kit and CD34. Infarcted heart tissue fragments were placed into dishes with BMSCs and medium supplemented with G-CSF, SCF, IGF-1 or combinations thereof were given to the BMSC-infarcted myocardium in vitro model. The IGF-1–G-CSF group showed significantly higher migration (67.7% ± 2.6) of c-kit+ BMSCs towards the ischemic tissue and expressed MEF-2 (43.7% ± 1.7). Of the single treatment groups, the G-CSF group demonstrated significantly higher migration of c-kit+ BMSCs (60.5 ± 2.7) with MEF-2 expression (38.7 ± 1.4). IGF-1 complements G-CSF and was relatively more significant in its effects on BMSC migration and cardiac lineage commitment towards ischemic heart tissue. [Copyright &y& Elsevier]
