Method of fabricating scaffold for tissue engineering

Abstract

A method of fabricating a scaffold for tissue engineering that includes a frame structure including one of poly-D-lactic acid and poly-L-lactic acid and a coating layer formed on a surface of the frame structure and including a lactic acid-glycolic acid copolymer. The method includes mixing a first granular porous substance including one of poly-D-lactic acid and poly-L-lactic acid with a second granular porous substance including the lactic acid-glycolic acid copolymer to prepare a mixture, and pressurizing and heating the mixture in a mold. In the heating, the mixture is heated to a temperature greater than or equal to the melting point of the lactic acid-glycolic acid copolymer and less than the melting point of one of poly-D-lactic acid and poly-L-lactic acid.

What is claimed is: 
     
         1 . A method of fabricating a scaffold for tissue engineering that includes
 a frame structure including one of poly-D-lactic acid and poly-L-lactic acid, and   a coating layer formed on a surface of the frame structure and including a lactic acid-glycolic acid copolymer, the method comprising:   preparing the frame structure including the one of poly-D-lactic acid and poly-L-lactic acid;   dispersing powder of the lactic acid-glycolic acid copolymer on the surface of the frame structure; and   heating the frame structure after the dispersing,   wherein in the heating, the frame structure is heated to a temperature greater than or equal to a melting point of the lactic acid-glycolic acid copolymer and less than a melting point of the one of poly-D-lactic acid and poly-L-lactic acid.
