Fixing a Broken Heart ... Through the Stomach
Scientists are looking to the stomach to help treat those suffering from heart attacks. Scientists used stem cell patches of lab-grown heart cells onto rats' stomachs' fatty tissue - which is rich in blood vessels and has previously been used to regenerate other organs. After a week, they transferred the patches to the rats’ damaged heart. Experiments showed that the patches did indeed improve the heart's condition.
Still, much work is needed as the procedure is considered too risky for elderly patients because of the extensive amount of surgery time required.
