Isolation of a new cardiac stem cell population

摘要

The invention relates to a novel population of cardiac stem cells which are positive for aldehyde dehydrogenase activity, express CD34, and do not express c-kit or CD45. These cells are different from previously identified cardiac stem cells, mesenchymal stem cells or HSCs. The invention provides methods for isolating these cells and the use of these cells and expanded cell populations thereof for use in heart repair.
