Abstract
Mesenchymal precursors cells have been isolated from perivascular niches from a range of tissues utilizing a perivascular marker. A new mesenchymal precursor cell phenotype is described characterized by the presence of the perivascular marker 3G5, and preferably also alpha smooth muscle actin together with early developmental markers such as STRO-1 and CD146/MUC18. The perivascular mesenchymal precursor cell is shown to induce neovascularisation and improvement in cardiac function. Suitable administration of preparations of the mesenchymal precursor cells are useful for treatment of cardiovascular diseases, cerebrovascular diseases and peripheral vascular diseases.

- 131. A method of inducing the formation or repair of blood vessels in a target tissue of a patient, the method comprising the step of administering to said patient an effective amount of an enriched population of cells that express the marker STRO-1.
- 172. A method of inducing formation or repair of blood vessels, the method comprising the steps of culturing and/or expanding an enriched population of cells that express the marker STRO-1, and contacting said cultured and/or expanded cells to tissue in need of blood vessel formation or repair in order to generate new blood vessels or to repair existing blood vessels.
- 173. A method of inducing repair of blood vessels in a patient suffering from a disease associated with loss of cells expressing alpha smooth muscle actin from vasculature or perivascular tissue, the method comprising the steps of culturing and/or expanding an enriched population of cells that express the marker STRO-1, and contacting said cultured and/or expanded cells to tissue in need of blood vessel repair in order to result in a coating of blood vessels with alpha-smooth muscle actin-positive cells.
- 187. The method of claim 187 wherein the cultured and/or expanded population comprises at least 0.01% MPCs capable of forming a clonogenic colony.
