But research is still in early stages and a long way from meeting regulatory approval. A team in Spain is currently building on the pioneering work of Dr Doris Taylor at the University of Minnesota, USA, who was able to develop a lab-grown beating rat heart in 2010, by implanting human stem cells into a rat heart scaffold which served as a blueprint for the stem cells to follow.
Dr Francisco Fernandez-Aviles and his team in Madrid are looking at bioengineering replacement human body parts, working to grow a human heart. They have already grown early-stage valves and patches that could one day be used to repair tissue damaged by heart attack
