Harvard team makes 'heart-on-a-chip' for faster drug testing
Harvard University researchers have developed a 'heart-on-a-chip', which can be used to test the reaction of heart tissue to external stimuli. The team replicated cardiac muscles using hydrogel as its mechanical properties are similar to heart's extracellular matrix. The hydrogel-making process, 60% faster than the older one, could boost mass production of organs on a chip, said researchers.
