Abstract：
 A porous support for cartrilage tissue engineering is prepared from the high-molecular material of polyethanediol, polyamide, or polyacrylic acid type as mould material, polyhydroxy alkanoate as polymer for the porous support chloroform as solvent and water-soluble crystal as pore-forming agent through smelting the said mould material, pouring it into a container in which there is a soft silica gel male mould, obtaining a high-molecular femal mould, filling the mixture of polymer solution and pore-forming agent particles in the said femal mould, closing compacting, baking to remove solvent, dissolving the mould and pore-forming particles, and drying.
