METHODS AND COMPOSITIONS FOR VASCULOGENIC POTENTIAL DETERMINATION
First Claim
1. A method of evaluating vasculogenic potential of endothelial cells, the method comprising:
- (a) culturing the endothelial cells (EC) and a plurality of adipose stromal cells (ASC); and
(b) evaluating the vasculogenic potential by the formation of a vascular network.

Abstract
Methods and compositions to evaluate the therapeutic vasculogenic potential of a variety of cells including endothelial cells using a monolayer of pericytic cells are disclosed. Pericytic cells or mural cells including those isolated from adipose tissue, such as for example, adipose stromal cells (ASC) or adipose-derived stromal cells (ADSCs) provide suitable conditions that stimulate endothelial cells from different origins to modulate stable vascular network organization in an in vitro experimental setting. Compositions that contain premixed ASC and EC are suitable for testing a candidate agent'"'"'s angiogenic or antiangiogenic potential.

17. A method of screening a candidate angiogenic or anti-angiogenic agent, the method comprising:
-
(a) culturing adipose stromal cells and endothelial cells capable of forming a vascular network in vitro; (b) contacting adipose stromal cells and endothelial cells with the candidate agent; and (c) determining that the candidate agent is angiogenic or anti-angiogenic if the candidate compound augments angiogenesis or inhibits angiogenesis by the comparing the vascular network formation to a control sample without the candidate compound.
