The invention provides a kind of collagen structure body, it is characterized in that: the collagen fiber being 1 ~ 5 μm by average diameter are formed, water content is 0 ~ 15 (w/w) %, and collagen density is 50 ~ 800mg/cmn 3 .Collagen protein acid solution is adjusted to neutral to generate collagen fiber, forms by filtration etc. the thick collagen fiber that collagen concentration is 12 ~ 50 (w/v) % afterwards.These thick collagen fiber are molded as regulation shape, and carrying out drying afterwards can obtain.Because this collagen structure body is for material with the collagen fiber of collagen molecules association formation, so cells infiltrating excellence, and the collagen tissue in collagen density and body is of equal value, so tissue regeneration power is excellent when being filled in the defect portion of body, be applicable to regenerative medicine artificial material etc. |
