Our expert physicians and surgeons provide a full range of dermatologic, reconstructive and aesthetic treatments options at Cleveland Clinic. The stromal cells are the supporting connective tissues (for example, blood vessels and elastic fibers). It involves a process that increases the amount of existing tissue available for reconstructive purposes. When a heart attack occurs, the heart muscle that has lost blood supply begins to suffer injury. Researchers are studying how to control the growth and differentiation of embryonic stem cells. In the final stages of "cell dying," the nucleus becomes shrunken (pyknosis) or fragmented (karyorrhexis). Laser resurfacing may be used to minimize wrinkles and refine hypertrophic scars. How much pumping function is lost depends on the size and location of the scar tissue. As the name implies, dermabrasion involves removing the top layers of skin with an electrical machine that abrades the skin.
