Bone marrow cells and ejection fraction improvements in the human heart

The crucial question of every stem cell transplantation whether the cellular incorporation or other happenings (paracrine effects) results in any functional improvement. In heart it was showed that functional and metabolic regeneration of infarcted and chronically avital tissue can be achieved in humans using transplantation of bone-marrow-derived cells {Brehm and Strauer, 2006, Nat Clin Pract… Continue reading Bone marrow cells and ejection fraction improvements in the human heart
