The result is that small vacuoles of fat accumulate and become dispersed within the cytoplasm. It consists of a layer of simple squamous epithelium, known as mesothelium, and a thin layer of underlying connective tissue. The majority of toxic effects, especially due to xenobiotics, are due to specific biochemical interactions without causing recognizable damage to a cell or its organelles.

Brain injury may happen in one of two ways: Closed brain injury. As the name implies, dermabrasion involves removing the top layers of skin with an electrical machine that abrades the skin. Transitional epithelia are a special subset of stratified epithelia that consist of ovoid cells that can stretch based on the pressure of liquids inside the organ. Skin grafts or skin flaps are done after the scar tissue is removed. That may be because of the location or because of damage to the vessels. Nearly everyone develops some type of scar, whether from an accident, a surgical procedure, acne or an illness like chickenpox (varicella).

Scientists have successfully transformed regular adult cells into stem cells using genetic reprogramming. Damage to the upper-middle surfaces of the frontal cortex is linked to becoming withdrawn and losing motivation. Scars are part of the bodys healing process. The response of cells to toxic injury may be transient and reversible once the stress has been removed or the compensatory cellular changes are made. Researchers are testing adult stem cells to treat other conditions, including a number of degenerative diseases such as heart failure. Over time, the pinkish color fades, and the scar becomes slightly darker or lighter than the color of the skin. Several treatments can make scars less noticeable.
