The experiment with the bioreactor "MSK-2" concluded a six-year orbital program.

3D cell spheroids, forming cartilage, were placed in a special setup onboard the station for several weeks and returned to Earth on December 9th.

Scientists are now analyzing how microgravity affects the structure of cartilage and its metabolism.

Since 2019, 11 series of bio-samples have been sent into space—ranging from stem cells to three-dimensional tissues.
