Abstract

The present invention provides a method for producing a cell culture for promoting angiogenesis or axon outgrowth, particularly for the treatment of a cerebrovascular disease, an ischemic cardiac disease or traumatic brain injury and spinal cord injury, which comprises culturing a cell population containing microglia and/or monocytes under conditions of low oxygen concentration and/or low sugar concentration to produce the culture, a cell preparation obtained by the method, and a method for treating a cerebrovascular disease, an ischemic cardiac disease or traumatic cerebrospinal neuropathy by using the cell preparation.

Claims (16)

1. A method for the promotion of angiogenesis and axon outgrowth in a subject, comprising administering to the subject a composition comprising a therapeutically effective amount of autologous microglia and/or monocytes, wherein the autologous microglia and/or monocytes are obtained by;

culturing the microglia and/or monocytes in the presence of oxygen at a concentration of 1% or less and glucose at a concentration of 1.0 g/L or less for a period of 12-24 hours, thereby obtaining microglia and/or monocytes with the ability to promote angiogenesis and axon outgrowth; and

wherein the composition is administered to the subject by intravenous administration, intraperitoneal administration, intracerebral administration, intraventricular administration, intraarterial administration, or local transplantation.

2. A method for the treatment of an ischemic cerebrovascular disease, traumatic brain injury, or spinal cord injury in a subject, comprising administering to the subject a composition comprising a therapeutically effective amount of autologous microglia and/or monocytes, wherein the autologous microglia and/or monocytes are obtained by;

culturing the microglia and/or monocytes in the presence of oxygen at a concentration of 1% or less and glucose at a concentration of 1.0 g/L or less for a period of 12-24 hours, thereby obtaining microglia and/or monocytes with the ability to promote angiogenesis and axon outgrowth; and

wherein the composition is administered to the subject by intravenous administration, intraperitoneal administration, intracerebral administration, intraventricular administration, intraarterial administration, or local transplantation.

3. The method of claim 1 , wherein the composition is administered to the subject by intravenous administration.

4. The method of claim 2 , wherein the composition is administered to the subject by intravenous administration.

5. The method of claim 1 , wherein the monocytes are collected from peripheral blood.

6. The method of claim 1 , wherein the monocytes are isolated from a fraction comprising mononuclear cells collected from peripheral blood.

7. The method of claim 1 , wherein the low oxygen concentration is an oxygen concentration of 0.1 to 0.4%.

8. The method of claim 1 , wherein the culture period is about 18 hr.

9. The method of claim 2 , wherein the monocytes are collected from peripheral blood.

10. The method of claim 2 , wherein the monocytes are isolated from a fraction comprising mononuclear cells collected from peripheral blood.

11. The method of claim 2 , wherein the low oxygen concentration is an oxygen concentration of 0.1 to 0.4%.

12. The method of claim 2 , wherein the culture period is about 18 hr.
