A new step in the science of physiology has been taken by the scientists as they have developed a structure that can support beating heart muscle, which brightens the possibility that human organs could be grown in the laboratory in near future.  

The scientists have developed a non-living material which they call "scaffold", which is strong enough to hold the organ tissue in place. Astonishingly, it has been designed in such a manner that it degrades in two months to leave the organ behind.
