A Robotic Fish (Made from Human Heart Cells)

Scientists have built a robotic fish from human heart cells. See why the biohybrid acts as an important model for medical researchers.

“By leveraging cardiac mechano-electrical signaling between two layers of muscle, we recreated the cycle where each contraction results automatically as a response to the stretching on the opposite side,” said Keel Yong Lee, Ph.D. , a postdoctoral fellow at SEAS and co-first author of the study. “The results highlight the role of feedback mechanisms in muscular pumps such as the heart.”
