Abstract
A method for producing a porous body comprising apatite/collagen composite fibers comprising the steps of gelling a dispersion comprising long apatite/collagen composite fibers having an average length of 10-75 mm, short apatite/collagen composite fibers having an average length of 0.05-1 mm, and a liquid; freezing and drying the resultant gel to form a porous body; and cross-linking collagen in the porous body.
Claims4
A method for producing a porous body comprising apatite/collagen composite fibers comprising:
- gelling a dispersion comprising long apatite/collagen composite fibers having an average length of 10-75 mm, wherein at least 90% by mass of the long apatite/collagen composite fibers has a length in the range of 5-100 mm, short apatite/collagen composite fibers having an average length of 0.05-1 mm, wherein at least 90% by mass of the short apatite/collagen composite fibers has a length in the range of 0.01-2 mm, and a liquid;
- freezing and drying the resultant gel to form a porous body;
- and
- cross-linking collagen in said porous body.
