    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.

    Abstract: The present invention relates to a biodegradable thermal-sensitive gel system, which comprises at least one polysaccharide solution, at least one electrolytic salt, and at least one buffer solution for adjusting pH. A natural protein as well as a cross-linking agent can be added to the gel system optionally. Said gel system is liquid at room temperature (25null C.) and solidifies at or above 37null C. The present invention also relates to a process for preparing said gel system, and a use for drug releasing carrier.
