23 Jul Cartilage tissue engineering scaffold composite material
Abstract
The present invention uses L-lactic acid polymer whose molecular weight is 80000-200000 and calcium polyphosphate fibre whose mean length is 5-15 mm and adopts dissolving casting granule leaching process to obtain the invented skeleton material capable of being transplanted in the body. As compared with tissue engineering scaffold material of existent technology said invented product possesses high voidage, good biological degradable property and physical mechanical property, and possesses three-D communication, micropore and reticular microstructure, so that it can completely meet the basic requirements for tissue engineering.
