Abstract: A collagen material is characterized in being constituted of collagen gel fragments. Furthermore, the collagen gel fragments may have an orientation. A method for producing a collagen material is characterized in comprising a step for preparing collagen gel fragments, a step for arranging the collagen gel fragments in a desired shape, and a step for drying the collagen gel fragments arranged in the desired shape. Moreover, in one embodiment of the method for producing a collagen material a step may include imparting an orientation to the collagen gel fragments.

Abstract: It is an object of the present invention to provide an oriented collagen/apatite material wherein an orientation is controlled, and a method of the oriented collagen/apatite material wherein an orientation is controlled. A method of producing an orientated collagen/apatite material according to the present invention, is characterized in that the method comprises; preparing a collagen having an orientation, seeding an osteoblast or a mesenchymal stem cell to produce and fix an apatite having an orientation similar to or almost the same as a direction of an orientation of the collagen on a surface and/or inside of the collagen. Furthermore, in a preferred embodiment of above mentioned method of producing an orientated collagen/apatite material according to the present invention, is characterized in that the osteoblast is an osteoblast like cell or an osteoblast obtained from a living organism.
