The process may someday make it possible to grow rejection-proof replacement valves for humans using a person's own cells, a process called autologous tissue engineering. "It's the first fabrication of an autologous heart valve inside a living body," said Kyoko Hayashida, M.D., lead author of the study and a research fellow at the National Cardiovascular Center Research Institute in Osaka,...
