Abstract: The present invention relates to the identification, isolation, expansion and characterization of a specific type of multipotent adult cardiac stem cell. These adult stem cells are characterised in that they naturally express a specific pattern of markers, which can be used to assist with their isolation and expansion. In particular, the cells express SOX17 and GATA4, but do not express Oct4, Nanog, c-kit and telomerase reverse transcriptase. These cells are able to differentiate into one or more of the following cell types: adipocytes, osteocytes, endothelial cells and/or smooth muscle cells. They also display an unprecedented capacity for immunoregulation as well as providing, activating and/or inducing repair of damaged cardiac tissue. These adult stem cells may be used as therapeutic agents including, without limitation, for the regeneration of tissue, particularly for regeneration of damaged cardiac tissue, such as myocardium.
