Bioengineers send cardiac muscle samples into space to study heart cell biology in microgravity

Mount Sinai’s Cardiovascular Research Institute is sending bioengineered human heart muscle cells and micro-tissues into space for the first time on NASA’s 29th SpaceX commercial resupply services mission, which launched Thursday, November 9. The “SpaceX CRS-29” mission is sending scientific research to the International Space Station (ISS), where the samples will stay for approximately 30 days before returning to Earth.
