Therapeutic angiogenesis by bone marrow-derived cell transplantation in myocardial ischemic tissue and skeletal muscle ischemic tissue
This invention provides methods of forming new blood vessels in diseased or damaged tissue in a subject, methods of increasing blood flow to diseased or damaged tissue in a subject, and methods of increasing angiogenesis in diseased tissue in a subject, which methods comprise: a) isolating autologous bone marrow-mononuclear cells from the subject; and b) transplanting locally into the diseased or damaged tissue an effective amount of the autologous bone-marrow mononuclear cells, thereby forming new blood vessels in the diseased or damaged tissue. The new blood vessels may be capillaries or collateral vessels in ischemic tissue or any site of angiogenesis. Also provided are methods of treating tissue in disease or injury by local transplantation with an effective amount of the autologous bone marrow-mononuclear cells so as to induce vascularization in such diseased tissue.
1. A method of forming new blood vessels in cardiac muscle tissue in a subject, wherein the subject is a human, which comprises:
a) isolating autologous bone marrow-mononuclear cells from the human, wherein the autologous bone marrow-mononuclear cells are isolated from bone marrow; and
b) transplanting locally into the cardiac muscle tissue an effective amount of the autologous bone-marrow mononuclear cells, resulting in formation of new blood vessels in the cardiac muscle tissue.
2. The method of claim 1 , wherein the new blood vessels comprise capillaries.
3. The method of claim 1 , wherein the new blood vessels comprise collateral vessels.
4. The method of claim 1 , wherein the cardiac muscle tissue is ischemic cardiac muscle tissue.
5. The method of claim 1 , wherein the cardiac muscle tissue is damaged cardiac muscle tissue.
6. The method of claim 5 , wherein the damaged cardiac muscle tissue is an artificially created site.
7. A method of increasing blood flow to cardiac muscle tissue in a subject, wherein the subject is a human, which comprises:
a) isolating autologous bone-marrow mononuclear cells from the human, wherein the autologous bone marrow-mononuclear cells are isolated from bone marrow; and
b) transplanting locally into the cardiac muscle tissue an effective amount of the autologous bone-marrow mononuclear cells so as to result in formation of new blood vessels in the cardiac muscle tissue, thereby increasing the blood flow to the cardiac muscle tissue in the human.
8. The method of claim 7 , wherein the new blood vessels comprise capillaries.
9. The method of claim 7 , wherein the new blood vessels comprise collateral blood vessels.
10. The method of claim 7 , wherein the cardiac muscle tissue is ischemic cardiac muscle tissue.
11. The method of claim 7 , wherein the cardiac muscle tissue is damaged cardiac muscle tissue.
12. The method of claim 11 , wherein the damaged cardiac muscle tissue is an artificially created site.
13. A method of treating diseased cardiac muscle tissue in a subject, wherein the subject is a human, which comprises:
a) isolating autologous bone-marrow mononuclear cells from the human, wherein the autologous bone marrow-mononuclear cells are isolated from bone marrow; and
b) transplanting locally into the diseased cardiac muscle tissue an effective amount of the autologous bone-marrow mononuclear cells so as to result in formation of new blood vessels, thereby treating the diseased cardiac muscle tissue in the human.
14. The method of claim 13 , wherein the diseased cardiac muscle tissue is ischemic cardiac muscle tissue.
15. The method of claim 13 , wherein the new blood vessels comprise capillaries.
16. The method of claim 13 , wherein the new blood vessels comprise collateral blood vessels.
17. A method of increasing angiogenesis in diseased cardiac muscle tissue in a subject, wherein the subject is a human, which comprises:
a) isolating autologous bone-marrow mononuclear cells from the human, wherein the autologous bone marrow-mononuclear cells are isolated from bone marrow; and
b) transplanting locally into the diseased cardiac muscle tissue an effective amount of the autologous bone-marrow mononuclear cells, thereby increasing angiogenesis in the diseased cardiac muscle tissue in the human.
18. The method of claim 17 , wherein the diseased cardiac muscle tissue is ischemic cardiac muscle tissue.
19. A method of treating heart failure in a mammal, wherein the subject is a human, which comprises:
a) isolating autologous bone-marrow mononuclear cells from the human, wherein the autologous bone marrow-mononuclear cells are isolated from bone marrow; and
b) transplanting locally into the heart an effective amount of the autologous bone-marrow mononuclear cells so as to result in formation of new blood vessels, thereby treating heart failure in the human.
20. The method of claim 19 , wherein the new blood vessels comprise capillaries.
