Biodegradable composite matrix for enhancing angiogenesis and method for producing the same

Abstract

A biodegradable composite matrix for enhancing angiogenesis. The matrix includes a biodegradable material and a phospholipid distributed in the biodegradable material as a liposome or micelle. Derivatives of phospholipid have chemo-attraction properties and thus induce the transfer of endothelial cells into the system through tropism-inductive mechanism. The biodegradable composite matrix induces an intracellular signal cascade that is different from cascade induced by a growth factor, and can coordinate with the growth factor-induced cascade to enhance angiogenesis. The present invention also includes the method for producing the biodegradable composite matrix.
