## Abstract

Disclosed herein are methods and compositions for stimulating angiogenesis, using cells descended from marrow adherent stromal cells that have been transfected with sequences encoding a Notch intracellular domain. Applications of these methods and compositions include treatment of ischemic disorders such as stroke.

## Claims

### Claim 1

A method for making a composition comprising angiogenin, angiopoietin-2 (ANG-2) and heparin-binding epidermal growth factor-like growth factor (HB-EGF), the method comprising
(a) providing a culture of mesenchymal stem cells (MSCs),
(b) contacting the cell culture of step (a) with a polynucleotide comprising sequences encoding a Notch intracellular domain (NICD) wherein said polynucleotide does not encode a full-length Notch protein,
(c) selecting cells that comprise the polynucleotide of step (b), and
(d) further culturing the selected cells of step (c) in the absence of selection and in the absence of trophic factors.

### Claim 2 (depends on 1)

The method of claim 1, wherein the composition further comprises one or more of basic fibroblast growth factor, leptin, platelet-derived growth factor-BB, hepatocyte growth factor, vascular endothelial growth factor and placental growth factor.

### Claim 3 (depends on 1)

The method of claim 1, wherein the MSCs are human MSCs.

### Claim 4 (depends on 1)

A method for repairing ischemic damage in a subject or in a tissue, the method comprising contacting the subject or tissue with a composition made according to the method of claim 1.

### Claim 5 (depends on 4)

The method of claim 4, wherein the ischemic damage results from cerebral ischemia, cardiac ischemia, ischemia of the bowel, ischemia of the limb, cutaneous ischemia, ocular ischemia or cerebral palsy.

### Claim 6 (depends on 4)

The method of claim 4, wherein the subject is a human.

### Claim 7 (depends on 4)

The method of claim 4, wherein the tissue is necrotic.

### Claim 8 (depends on 1)

A composition comprising angiogenin, ANG-2 and HB-EGF made by the method of claim 1.

### Claim 9 (depends on 8)

The composition of claim 8, further comprising one or more of basic fibroblast growth factor, leptin, platelet-derived growth factor-BB, hepatocyte growth factor, vascular endothelial growth factor and placental growth factor.

### Claim 10 (depends on 8)

The composition of claim 8, wherein the composition is a conditioned medium.

### Claim 11 (depends on 8)

A therapeutic composition comprising the composition of claim 8 and a pharmaceutically acceptable carrier.

### Claim 12 (depends on 11)

A method for repairing ischemic damage in a subject or in a tissue, the method comprising contacting the subject or tissue with the therapeutic composition of claim 11.

### Claim 13 (depends on 12)

The method of claim 12, wherein the ischemic damage results from cerebral ischemia, cardiac ischemia, ischemia of the bowel, ischemia of the limb, cutaneous ischemia, ocular ischemia or cerebral palsy.

### Claim 14 (depends on 12)

The method of claim 12, wherein the subject is a human.

### Claim 15 (depends on 12)

The method of claim 12, wherein the tissue is necrotic.
