Following this transient event, which is believed to be of little importance to the inflammatory response, the blood vessels dilate ( vasodilation ), increasing blood flow into the area. Researchers have discovered ways to direct stem cells to become specific types of cells, such as directing embryonic stem cells to become heart cells. In some cells, they no longer can metabolize fatty acids so that lipids accumulate in the cytoplasmic vacuoles, referred to as "fatty accumulation" or "fatty degeneration." Multiple treatments may be required, regardless of the initial type of therapy.
