Harvard University researchers collaborated with colleagues from Emory University to develp the first fully autonomous biohybrid fish from human stem-cell derived cardiac muscle cells. Professor George Lauder and PhD candidate Dave Matthews joined researchers from the John A. Paulson School of Engineering and Applied Sciences (SEAS) and Emory University on the study published in Science. The artificial fish swims by recreating the muscle contractions of a pumping heart. The device offers insights into artificial muscular pumps and brings researchers closer to building an artificial heart.
