A research team at the University of Minnesota spent years trying to 3D print functional heart muscle cells derived from human stem cells—but fell short each time. Finally, however, just as they were ready to give up, two PhD students suggested printing the stem cells first—and it worked.

Those two PhD students, Molly Kupfer and Wei-Han Lin, and the rest of the team wrote about their experience in a study for Circulation Research. Brenda M. Ogle, PhD, head of the department of biomedical engineering at the University of Minnesota College of Science and Engineering, was the study’s corresponding author.

“We decided to give it one last try,” Ogle said in a statement. “I couldn’t believe it when we looked at...
