<P> Depending upon the degree of mineralization , collagen tissues may be either rigid ( bone ) or compliant ( tendon ) or have a gradient from rigid to compliant ( cartilage ) . It is also abundant in corneas , blood vessels , the gut , intervertebral discs , and the dentin in teeth . In muscle tissue , it serves as a major component of the endomysium . Collagen constitutes one to two percent of muscle tissue and accounts for 6 % of the weight of strong , tendinous muscles . The fibroblast is the most common cell that creates collagen . Gelatin , which is used in food and industry , is collagen that has been irreversibly hydrolyzed . Collagen also has many medical uses in treating complications of the bones and skin . </P>
