  "textContent": "Fibrosis is the body's way of patching up damage—a bit like fixing a pothole. When skin is cut or a muscle is injured, fibroblast cells rush in to make fibronectin and collagen, which are two major extracellular matrix proteins in tissue. They pull the wound edges together and build a temporary scaffold to let tissue heal. Once the job is done, the body slowly removes the extra fibers and the tissue softens again. This type of normal wound healing is essential. However, problems arise when fibroblasts do not stop making fibers. Instead of healing and calming, the tissue becomes thicker, stiffer, and less able to work. This long-term, uncontrolled scarring is called pathological fibrosis.",
