In vivo angiogenesis assay
First Claim
1. A method of performing an in vivo angiogenesis assay which comprises:
- providing a liquid matrix material which forms a matrix gel when injected into a host wherein said liquid matrix material is MATRIGEL;
adding an angiogenesis inducing or inhibiting agent to said liquid matrix material;
injecting said liquid matrix material containing said angiogenesis inducing or inhibiting agent into a host to form a matrix gel;
recovering said matrix gel from said host; and
quantitating angiogenesis of said recovered matrix gel.

Abstract
A method of performing in vivo angiogenesis assays which involves the use of a matrix material which can be maintained in an injectable solution form at a temperature below that of a host and which forms a gel matrix when injected into a host. The matrix material is an extract of murine basement membrane. Angiogenic factors, including inducers and inhibitors can be added to the matrix material prior to injection into a host. After a period of time within the host, the gel matrix is recovered and angiogenesis of the recovered matrix gel is quantitated. The procedure can be used to induce vascularization or inhibit vascularization at a tissue situs as desired.
