Living embryonic heart cells prevent cardiac arrhythmias

Researchers implant embryonic cells into damaged hearts and prevent life-threatening heart arrhythmias.
– When researchers at Cornell, the University of Bonn and the University of Pittsburgh transplanted living embryonic heart cells into cardiac tissue of mice that had suffered heart attacks, the mice became resistant to cardiac arrhythmias, thereby avoiding one of the most dangerous and fatal consequences of heart attacks.

Heart needs rhythm even before it has blood to pump

Baby hearts need rhythm to develop correctly – To develop correctly, baby hearts need rhythm even before they have blood to pump. “We have discovered that mechanical forces are important when making baby hearts,” said Mary Kathryn Sewell-Loftin, a Vanderbilt graduate student working with a team of Vanderbilt engineers, scientists and clinicians attempting to grow replacement heart valves from a patient’s own cells.
