TECHNICAL FIELD 0007 An in vitro model of angiogenesis has been created 0001. The present invention relates to novel nucleic acid from human umbilical vein ECs plated onto a 3 dimensional Sequences (“angiogenic genes”) involved in the process of collagen matrix (Gamble et al., 1993). In the presence of angiogenesis. Each of the angiogenic genes encode a phorbol myristate acetate (PMA) these cells form capillary polypeptide that has a role in angiogenesis. In View of the tubes within 24 hours. With the addition of anti-integrin realisation that these genes play a role in angiogenesis, the antibodies, the usually unicellular tubes (thought to reflect invention is also concerned with the therapy of pathologies an immature, poorly differentiated phenotype) are converted asSociated with angiogenesis, the Screening of drugs for pro to form a multicellular lumen through the inhibition of or anti-angiogenic activity, the diagnosis and prognosis of cell-matrix interactions and promotion of cell-cell interac pathologies associated with angiogenesis, and in Some cases tions.

The use of the in existing vessels, a process termed angiogenesis, is essential vitro model described above (Gamble et al., 1993), a model for normal growth. Important angiogenic processes include that reflects the critical events that occur during angiogen those taking place in embryogenesis, renewal of the esis in Vivo in a time dependent and broadly Synchronous endometrium, formation and growth of the corpus luteum of manner, has provided a tool for the identification of the key pregnancy, wound healing and in the restoration of tissue genes involved.
