Abstract
The present invention encompasses an adipose-derived adult stromal (ADAS) cell exhibiting at least one characteristic of a pre-endothelial cell and/or an endothelial cell. The present invention also encompasses compositions and methods for generating an adipose-derived adult stromal to exhibit at least one characteristic of a pre-endothelial cell and/or an endothelial cell. Methods for using the cells in vascular transplantation, tissue engineering, regulation of angiogenesis, vasculogenesis, and the treatment of numerous disorders including heart disease are also included.

- 10. A method of differentiating an isolated adipose tissue-derived adult stromal (ADAS) cell to express at least one characteristic of a pre-endothelial cell, the method comprising incubating said cell in MII medium followed by incubating said cell in MIII medium.
- 19. A differentiation medium for differentiating an isolated adipose tissue-derived adult stromal (ADAS) cell into a cell exhibiting at least one characteristic of a pre-endothelial cell, wherein said medium is supplemented with N2 supplement, B27 supplement, glutamine and fibroblast growth factor (FGF), further wherein said medium is designated as MII medium.
- 22. A differentiation medium for differentiating an isolated adipose tissue-derived adult stromal (ADAS) cell into a cell exhibiting at least one characteristic of a pre-endothelial cell, wherein said medium is supplemented with N2 supplement, B27 supplement, glutamine, nicotinamide and fetal bovine serum (FBS), further wherein said medium is designated as MIII medium.

31. A method of determining the ability of a compound to affect the differentiation of an isolated adipose tissue-derived adult stromal (ADAS) cell into a pre-endothelial cell and/or endothelial cell, the method comprising:
-
a) culturing said ADAS cell in a stromal cell medium for a period of time;
b) replacing said stromal cell medium with a differentiation medium comprising a compound or a control vehicle;
c) incubating said ADAS cell in said differentiation medium comprising said compound or said control vehicle for a period of time;
d) determining the number or percentage of differentiated cells using said differentiation medium comprising said compound from step (c);
e) determining the number of percentage of differentiated cells in the cells using said differentiation medium containing said vehicle alone from step (c);
f) comparing the number or percentage of differentiated cells from steps (d) and (e);
g) a greater number of percentage of differentiated cells from step (d) compared to the number of percentage of differentiated cells from step (e) indicates that said compound is capable of inducing differentiation of said ADAS cell into a pre-endothelial cell and/or endothelial cell. - View Dependent Claims (32)
