INTRO: With its tail flipping rhythmically from side to side, this strange synthetic fish scoots around in its salt and glucose solution, using the same power as our beating hearts. This nifty miniaturized circulatory system, developed by scientists at Harvard and Emory universities, can keep swimming to the beat for more than 100 days.
The inventors have high hopes for the strange little device, composed of living heart muscle cells (cardiomyocytes) grown from human stem cells. The creation of the 'biohybrid' fish focuses on two key regulatory features of our hearts: their ability to function spontaneously, without need for conscious input (automaticity); and messaging initiated by mechanical motion (mechanoelectrical signaling).
This insights learned from the research will hopefully allow researchers to more closely examine these aspects in heart diseases. "Our ultimate goal is to build an artificial heart to replace a malformed heart in a child," says Harvard University bioengineer Kevin Kit Parker... (MORE - details)
