Two kinds of scattering profiles were recognized ; crystalline diffraction spots and the amorphous diffuse scattering halo. The crystalline diffraction spots were broad in a younger tendon. However, they became sharper with aging. The amorphous diffuse halo that is marked in young tendon diminishes with aging. These results indicate that 1 ; the collagen fiber of a young tendon contains many crystal defects, 2 ; the content of proteoglycan in an younger tendon is higher than that in an older tendon. The x-ray diffraction profile becomes clear with aging., Connective tissue, 33(3), pp. 209-211; 2001}, pages = {209--211}, title = {Increased Crystallinity but Unchanged Crystallographic Fiber Period of Collagen Fiber with Aging}, volume = {33}, year = {2001} }
