Harvard University researchers have 3D-printed human heart tissue on a chip with integrated sensors, marking a major breakthrough for personalized medicine.

Tissue-on-a-chip technology may someday lead to replicating a patient’s specific genetic disorder in a laboratory, matching the properties of a disease or even an individual patient’s cells for testing and treatment purposes.

The results of the research by Harvard’s John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering at Harvard were published in the peer-reviewed journal Nature Materials.
