The role of tissue factor in the regulation of extracellular matrix remodelling and angiogenesis.

Funded Activity Summary

The aim of the project is to understand how some blood clotting factors may be involved with the regulation of the extracellullar matrix (the material that exists between cells) and angiogenesis (new blood vessel formation). New blood vessel growth occurs in a wide variety of situations including: healing of a flesh wound, the healing phase following a heart attack, development of the eye disease associated with sugar diabetes, in and around a cancerous growth, in the uterus during the normal menstrual cycle, and for the normal growth and development of the placenta and a new baby. The processes by which these new blood vessels form and the factors contributing to the maintenance of their structure are incompletely understood. However, it is known that the interaction of cells and the surrounding extracellular matrix is critical for normal cell function and in particular for new blood vessel formation. Studies in this project will seek to define a relationship between some of the factors which regulate blood clotting, and those that regulate turnover of the extracellular matrix and new blood vessel formation. In particular, how blood clotting factors may be invovled in the regulation of the extracellular matrix will be studied in a rapidly developing tissue, the mouse placenta. The role of blood clotting factors in regulation of new blood vessel formation into an artificial avascular tissue will also be examined. These studies will employ some of the new genetic techniques to understand new roles for proteins which have been traditionally thought to act in only one way. This research has the potential to provide new insights into how blood vessels are formed and are subsequently maintained. This increased understanding will provide the knowledge required for the development of new therapeutic strategies to correct the process when it goes wrong, is unwanted or underdeveloped in human disease.
