When a scar develops, collagen fibers repair damaged skin and close any open areas. Beneath the dermis lies the hypodermis, which is composed mainly of loose . The mesothelium produces serous fluid, which lubricates the outer wall of the stomach and ensures its smooth movement in the abdominal cavity. Tissue Engineering is the application of science to improve, restore and maintain the damaged tissues or the whole organ. It consists of a layer of simple squamous epithelium, known as mesothelium, and a thin layer of underlying connective tissue. In some instances, the organism can continue to live with the aid of medical treatment, for example, replacement of insulin or by organ transplantations. Researchers are studying how to control the growth and differentiation of embryonic stem cells. This is not used often. You may not have to live with a scar that bothers you. One type of collagen (made from purified cow collagen) is injected beneath the skin. A severe spasm can cause a heart attack. The cell disintegrates into fragments referred to as "apoptotic bodies."
