Astronauts’ Cardiac Woes in Space Revealed by Bioengineered Heart Tissue Experiment
- Heart tissues sent to the ISS showed reduced strength compared to Earth-based samples
- Low gravity impacts heart cells’ contraction and irregular beating patterns
- Inflammation and oxidative damage observed in space-bound tissue
- Mitochondria size increased, affecting energy production
- Long-term space missions could have implications for astronaut health
Scientists from Johns Hopkins University sent heart tissue samples to the International Space Station (ISS) for a study on the effects of spaceflight on astronauts’ heart health. The bioengineered tissues, created from human induced pluripotent stem cells and grown in ‘organ-on-a-chip’ devices, showed reduced contraction strength and irregular beating patterns compared to Earth samples. Inflammation and oxidative damage were observed, as well as changes in mitochondria size affecting energy production. These findings have implications for long-term space missions.
