Description; General description; Collagen constitutes to one-third of the total protein in humans. Collagen fibril is the basic component of the tissues containing collagen. It is predominantly expressed in the extracellular matrix.; Type I collagen is a major structural component of skin, bone, tendon, and other fibrous connective tissues. It differs from other collagens by its low lysine hydroxylation and low carbohydrate composition. Type I collagen is a heterotrimer composed of two α1(I) chains and one alpha2(I) chain, which spontaneously form a triple helix scaffold at neutral pH and 37 °C. This product is prepared from the extracellular matrix secreted by normal human fibroblasts and contains a high monomer content. In vitro cultures were prepared using intensively tested human fibroblast cells and purified using a manufacturing process following applicable aspects of cGMP. This process contains built-in, validated steps to insure inactivation of possible prion and/or viral contaminants.; Application; Purified human collagen solution is produced from neo-natal human fibroblasts that have secreted human extracellular matrix (hECM) using a propriety cell culture production system. The human fibroblast cells have undergone significant testing demonstrating safety from viruses and other adventitious agents. Collagen Solution from human fibroblasts has been used as a component of coating solution for human bone marrow chip fabrication. It has also been used in fibroblast-like synoviocytes culturing.; Biochem/physiol Actions; Collagen is an essential ingredient of connective tissue. Studies in a Chinese family show that mutation in COL1A1 (collagenase type I) is linked with type I osteogenesis imperfecta. Collagen is linked with subchondral turnover of bone, and might have potential as marker to determine the state of joint space narrowing and osteophytes in osteoarthritis.; Proteins belonging to the collagen family supports and nourishes body tissues such as tendons, cartilage, skin and sclera of the eye. Collagen type 1 is a versatile building material required for tissue elasticity and maintains its stability and strength. Collagen is also present in byssus thread of invertebrates, which helps in surface attachment. Defective collagen affects the biomechanical property of arterial tissues.
