According to Medline, MatriStem, a parchment-like sheet made from specific layers of pig bladder, is a natural extracellular matrix that can be applied to the site of an injury or damaged skin in order to encourage the body’s own capabilities to repair and restore tissue.
Placed in a wound bed, MatriStem provides a three-dimensional structural scaffold for cells and utilizes a specialized structure known as the basement membrane, which acts as a medium through which epithelial cells rebuild themselves, said Medline.
Thomas Gilbert, research assistant professor in the department of surgery and bioengineering at the University of Pittsburgh, said: “MatriStem facilitates wound healing by establishing an environment at the injury site that modulates the immune response and recruits a population of cells that are capable of healing the wound with new tissue instead of forming a scar.”
