Answer: A Type I
A mature scar is composed primarily of type I collagen. By contrast, the early matrix of granulation tissue contains proteoglycans, glycoproteins, and type III collagen.
Eventually, the temporary matrix is removed by a combination of extracellular and intracellular digestion, and the definitive matrix is deposited.
Extracellular crosslinking of the newly synthesized type I collagen progressively increases wound strength.
Collagen type II is found in cartilage. Collagen type IV is found in basement membranes. Collagen types V and VI are found in various organs.
