Abstract: Methods to treat heart failure and reduce systemic inflammation are provided. The methods include systemically delivering to a subject at least two doses, for example 2-10 doses, of mesenchymal stem cells, wherein the at least two doses are separated by an interval of time, such as from 1 day to 1 year.

Abstract: Provided are pharmaceutical compositions that include a pharmaceutically acceptable carrier and isolated post-natal cardiac progenitor cells (CPCs) and/or progeny cells thereof that are SSEA3-positive and c-kit-negative. Also provided are methods for preparing cells capable of repairing damaged myocardium, methods for isolating populations of SSEA3-positive/c-kit-negative CPCs from cardiac tissue samples, methods for preparing an isolated cell population enriched in post-natal SSEA3-positive/c-kit-negative CPCs, therapeutic methods for using the presently disclosed cells and populations of cells to treat subjects in need thereof, and cell cultures that contain the presently disclosed cells and populations of cells.

Abstract: The presently disclosed subject matter provides an isolated subpopulation of bone marrow-derived adherent stem cells that are purified from bone marrow-derived adherent cells. Also provided are methods for isolating the subpopulation of bone marrow-derived adherent stem cells from bone marrow-derived adherent cells and for using the isolated subpopulation of bone marrow-derived adherent stem cells for treating tissue and/or organ damage in a subject.

Abstract: Disclosed are methods for inducing cardiomyogenic differentiation in cells that are competent for differentiation along the cardiomyogenic lineage such as certain unfractionated bone marrow mononuclear cells (BMMNCs). In some embodiments, the methods include contacting a plurality of unfractionated, density gradient-separated BMMNCs with a cardiomyocyte differentiation-inducing amount of a Wnt11 gene product for a time and under conditions sufficient to induce cardiomyocyte differentiation in at least a subset of the BMMNCs. Also provided are methods for treating an injury to cardiac tissue in a subject using cells that have been induced to differentiate along the cardiomyogenic lineage, recombinant host cells comprising an expression vector that encodes a Wnt11 polypeptide or a functional fragment thereof, and systems for inducing cardiomyogenic differentiation in a cultured cell.
