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.

Collagen material and method for producing collagen material

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.
