Here are some answers to frequently asked questions about stem cells. A heart attack occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or cut off completely. It is the next chapter in organ transplantation and uses cells instead of donor organs, which are limited in supply. Some researchers believe that stem cells derived from therapeutic cloning may offer benefits over those from fertilized eggs because cloned cells are less likely to be rejected once transplanted back into the donor and may allow researchers to see exactly how a disease develops. The fibrotic scar tissue shores up the damage but it cannot replace the function of the lost hepatic tissue. The most common burns are those caused by hot liquid or steam, building fires, and flammable liquids and gases.

The different types of necrosis include: . When a coronary artery narrows and constricts blood flow, other nearby blood vessels that serve the heart sometimes expand to compensate, which may explain why there may be no warning signs. There are three main types of wound healing, depending on treatment and wound type. These apoptotic bodies and the organelles are phagocytized by adjacent cells and local macrophages without initiation of an inflammatory response as is seen in necrosis. Many different types of cells are involved in wound repair, especially if the surface area that needs repair is extensive.
