The only problem is that they are not sure that it will corectly work with the rodents let alone human hearts. This is more like a biological
defibulator than just more heart tissue. Although it replicates the rodents heart well and works in unison with the other heart cells which is key in
order to make the tissue work. The tissure itself is pretty amazing since just like other tissues in the human body, the heart tissue does not regrow
so this could be a possible new way to solve the heart transplant shortage.
