Researchers funded by the Society reported that a specific type of nerve cell called "projection neurons" - which normally facilitate communication between different areas of the brain - are especially vulnerable to damage in the cortex (the outer region of the brain, associated with disease progression and cognitive impairment). Researchers haven't been able to successfully perform therapeutic cloning with humans despite success in a number of other species. When tissue is first injured, the small blood vessels in the damaged area constrict momentarily, a process called vasoconstriction. The process of atherosclerosis may have no symptoms in its early stages. The fibrotic scar tissue shores up the damage but it cannot replace the function of the lost hepatic tissue.

The healthy transplanted heart muscle cells could then contribute to repairing the injured heart muscle. Damage to one cell type prompts reactions within the tissue to compensate for the injury. Phases of the Wound Healing Process. Here are the possible solutions for "Area of damaged tissue" clue. The skin repairs itself by growing new tissue to pull together the wound and fill in any gaps caused by the injury. When a heart attack occurs, the heart muscle that has lost blood supply begins to suffer injury. The regenerating cells come from the proliferation of nearby parenchymal cells, which serve to replace the lost cells. Cardiac arrest may be reversed if CPR (cardiopulmonary resuscitation) is performed and a defibrillator is used within minutes to shock the heart and restore a normal heart rhythm. People with dark skin (especially people with African, Asian or Hispanic heritage), as well as red-haired individuals, are more likely to develop keloid scars.
