Endocardial versus epicardial differences of intracellular free calcium under normal and ischemic conditions in perfused rat hearts.

abstract：:Peripheral blood (PB)-derived CD14+ monocytes were shown to transdifferentiate into endothelial cell (EC) lineage cells and contribute to neovascularization. We investigated whether bone marrow (BM)- or PB-derived CD34-/CD14+ cells are involved in reendothelialization after carotid balloon injury. Although neither hem...
