As a porous apatite hydroxide support formed using apatite hydroxide as a starting material, coarse pores of 180-360 μm are formed into a mesh, micropores of 2 μm or less are formed inside the support skeleton, and the micropores are uniaxially. A porous apatite hydroxide support having a relatively high compressive strength (4.03-6.5 MPa) corresponding to a porosity (55-91%) characterized by regular growth in the direction to form a channel is disclosed. According to the present invention, in order to design a porous support that meets the requirements of bone tissue engineering, polymer sponge technology is used to form a superporous having a coarse pore network structure, improving mechanical strength by gel process, and controlling freezing. The orientation of micropores by casting can be obtained. |
