Described as “hearts on a chip,” the engineered heart tissues are produced through 3D bioprinting with a bio-ink developed in Savoji’s laboratory using patient-harvested stem cells, enabling personalized human heart models to be created.

Led by UdeM pharmacology and physiology professor Houman Savoji at his laboratory at CHU Sainte-Justine, along with UdeM Ph.D. student Ali Mousavi, the research is detailed in a study published in the journal Small. An initial version of the technology was published two years ago, in a study in Applied Materials Today.
