In this situation, the cell has become damaged and is unable to adequately metabolize fat. Yes, burned skin can be permanent. Tissue Engineering (TE) is an interdisciplinary field that encompasses materials science in combination with biological and engineering sciences. Cellular changes. Area of damaged tissue (6) I believe the answer is: lesion I'm a little stuck. International Society for Stem Cell Research. A burn is tissue damage caused by heat, chemicals, electricity, sunlight, or nuclear radiation. changed the way researchers think about MS, discovered that unique antibody patterns are associated with different lesion patterns, which could lead to a blood test to help inform treatment decisions, made significant gains in understanding when lesions form and how tissue is damaged, opening up new possibilities for strategies to stop that damage. If the programmed cells do not die, the fetus ends up with incomplete or fingers joined together in a web fashion. It is nearly impossible to separate a discussion of cellular toxicity and biochemical toxicity. This happens when coronary arteries that supply the heart muscle with blood flow become narrowed from a buildup of fat, cholesterol and other substances that together are called plaque.
