THREE-DIMENSIONAL POROUS SUPPORT BODY AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a three-dimensional porous support body, and to a method for manufacturing same. The three-dimensional porous support body of the present invention has a structure in which a biodegradable multifilament false twist yarn to which extra bulk is imparted is inserted into a tube-shaped circular knitwork consisting of biodegradable polymers. The three-dimensional porous support body is porous due to the network structure of the circular knitwork due to the 10-150 µm pores contained in the biodegradable multifilament false twist yarn, and also has superior internal connectivity due to the extra bulk of 150-1000% imparted to the biodegradable multifilament false twist yarn that is fixedly inserted into the circular knitwork. Accordingly, the support body is optimized for cell culturing, cell delivery, and drug delivery since it has a stable three-dimensional structure.
