Tissue Chips Sent To Space To Test Human Health, Genetic Changes

The "Tissue Chips in Space" initiative seeks to better understand the role of microgravity on human health and disease and to translate that understanding to improved human health on Earth, NASA said.

NASA is planning to send small cells containing human cells in a 3D matrix – known as tissue chips or organs-on-chips – to the International Space Station (ISS) to test how they respond to stress, drugs and genetic changes.

Space Medicine With Stem Cells In ISS Microgravity

Space Tango of Lexington today announced a research collaboration to study Parkinson's disease (PD) and primary progressive multiple sclerosis (PPMS) in microgravity in conjunction with National Stem Cell Foundation (NSCF), Summit for Stem Cell Foundation, and New York Stem Cell Foundation ( NYSCF) Research Institute.

For the first time, cells with PD and PPMS will be sent to the International Space Station (ISS) for a unique opportunity to observe cell-to-cell interactions in the neurodegenerative disease when the gravitational forces act on cells are removed.

Space Travel Affects Brain

Spending long periods in space not only leads to muscle atrophy and reductions in bone density, but it also has lasting effects on the brain. However, little is known about how different tissues of the brain react to exposure to microgravity, and it remains unclear whether and to what extent the neuroanatomical changes so far observed persist following return to normal gravity.

The study was published in the  New England Journal of Medicinethey show that differential changes in the three main tissues of the brain remain detectable for at least half a year after the end of their last mission.

Long-Duration Flights Has Surgery Care In Space

Astronauts on long-duration flights will need access to more than just routine care. The concept of human space exploration has experienced something of a recent revival in the public consciousness.

The private SpaceX and Virgin Galactic companies (and their eccentric front men) often make front-page news for their achievements and goals, which ultimately involves traveling to and colonizing distant planets.

Though some decry these ambitions as extravagant fantasies, news pertaining to novel developments in extraterrestrial exploration often goes viral over digital media, reflecting a genuine public interest in the topic.

Astronauts Living In Microgravity Provided With Spacemedicine

Imagine you are an astronaut on the surface of Mars, driving to rover down an incline into a crater. The vehicle's specially designed tires slip on the steep surface, and the rover begins to slide uncontrollably toward a large rock at the floor of the crater. The impact is sudden, you are thrown forward against the restraint straps, and your head hits the inside of the space-suit helmet.
