MINNEAPOLIS / ST. PAUL (January, 13 2008) — University of Minnesota researchers have created a beating heart in the laboratory.

By using a process called whole organ decellularization, scientists from the University of Minnesota Center for Cardiovascular Repair grew functioning heart tissue by taking dead rat and pig hearts and reseeding them with a mixture of live cells. The research will be published online in the January 13 issue of Nature Medicine. (more…)
