Cardiac muscle regeneration using mesenchymal stem cells
View Patent ↗Disclosed is a method for producing cardiomyocytes in vivo by administering to the heart of an individual a cardiomyocyte producing amount of mesenchymal stem cells. These cells can be administered as a liquid injectible or as a preparation of cells in a matrix which is or becomes solid or semi-solid. The cells can be genetically modified to enhance myocardial differentiation and integration. Also disclosed is a method for replacing cells ex vivo in a heart valve for implantation.
1. A process for treating cardiac ischemia in a patient, comprising:
administering to the patient human allogeneic mesenchymal cells in an amount effective to treat cardiac ischemia in the patient such that the cardiac ischemia is treated.
2. The process of claim 1 , wherein the mesenchymal stem cells are administered intravenously.
3. The process of claim 1 , wherein the mesenchymal stem cells are administered in a pharmaceutically acceptable liquid carrier.
4. The process of claim 3 , wherein the pharmaceutically acceptable carrier comprises an isotonic liquid.
5. The process of claim 4 , wherein the isotonic liquid comprises phosphate buffer saline, physiological saline or 5% dextrose in water.
6. The process of claim 1 , wherein the mesenchymal stem cells are administered in a suspension containing about 10×10 6 to about 40×10 6 mesenchymal stem cells per ml.
7. The process of claim 6 , wherein the cell suspension is administered in an amount of about 20 μl to about 150 ml.
8. The process of claim 6 , wherein the cell suspension is at least about 20 μl.
9. The process of claim 6 , wherein the cell suspension is at least about 500 μl.
