Relative roles of direct regeneration versus paracrine effects of human cardiosphere-derived cells transplanted into infarcted mice.
RATIONALE Multiple biological mechanisms contribute to the efficacy of cardiac cell therapy. Most prominent among these are direct heart muscle and blood vessel regeneration from transplanted cells, as opposed to paracrine enhancement of tissue preservation and/or recruitment of endogenous repair. OBJECTIVE Human cardiac progenitor cells, cultured as cardiospheres (CSps) or as CSp-derived cel...
متن کاملSafety and efficacy of allogeneic cell therapy in infarcted rats transplanted with mismatched cardiosphere-derived cells.
BACKGROUND Cardiosphere-derived cells (CDCs) are an attractive cell type for tissue regeneration, and autologous CDCs are being tested clinically. However, autologous therapy necessitates patient-specific tissue harvesting and cell processing, with delays to therapy and possible variations in cell potency. The use of allogeneic CDCs, if safe and effective, would obviate such limitations. We com...

متن کاملCardiosphere-Derived Cells Require Endoglin for Paracrine-Mediated Angiogenesis
Clinical trials of stem cell therapy to treat ischemic heart disease primarily use heterogeneous stem cell populations. Small benefits occur via paracrine mechanisms that include stimulating angiogenesis, and increased understanding of these mechanisms would help to improve patient outcomes. Cardiosphere-derived-cells (CDCs) are an example of these heterogeneous stem cell populations, cultured ...
متن کاملCharacterization of the paracrine effects of human skeletal myoblasts transplanted in infarcted myocardium.
BACKGROUND The discrepancy between the functional improvements yielded experimentally by skeletal myoblasts (SM) transplanted in infarcted myocardium and the paucity of their long-term engraftment has raised the hypothesis of cell-mediated paracrine mechanisms. METHODS AND RESULTS We analyzed gene expression and growth factors released by undifferentiated human SM (CD56(+)), myotubes (SM cult...
