Collagen is Type I soluble, salt free component of skin, bone, tendon, and other fibrous connective tissues. Type I collagen differs from other collagens by their low lysine hydroxylation and low carbohydrate composition. Collagen breaks down metabolically in the body to release N-telopeptide, which is the N-terminus of collagen. There is also C-telopeptide, which is presumably the C-terminus. N-telopeptide is released in urine, and its detection in diagnostic tests is used to screen for osteoporosis. Collagen Type I has been used as a scaffold for the growth of stem cells in vitro, in a wide variety of biomaterial engineering studies. Collagen type I may be used in research of Idiopathic pulmonary fibrosis (IPF). Robust expression of collagen-type 1 is one distinctive feature of IPF. Additionally, collagen-type I has been used in studies on the effect of endoplasmic reticulum (ER) stress from IPF on myofibroblastic differentiation of lung fibroblasts. Collagen-type 1 soluble in acidic solution produces three dimensional scaffolding useful in bioengineering and cell culture applications where biomaterials are needed to replace native collagen extracellular matrices. It is prepared according to the method of Gallop and Seifter. In the method, fresh calf skin is extracted with 0.5 M NaOAc to remove non-collagen proteins. The soluble collagen is extracted with 0.075 M Sodium citrate, pH 3.7, and precipitated as fibrils by dialysis against 0.02 M Na2HPO4.
