Scaffold-Free Tissue Self-Assembly in Microgravity

Interactive 3D bioreactor simulator: watch cell spheroids self-assemble into a scaffold-free 3D tissue construct through differential-adhesion surface tension, and see how switching on gravity makes the construct sediment and flatten under its own weight.

Small cell spheroids float inside a virtual bioreactor and behave like viscous liquid droplets: differential adhesion between their surfaces pulls them together and fuses touching spheroids into a single larger, rounder construct, exactly as tissue-engineering labs use rotating-wall-vessel and orbital bioreactors to grow scaffold-free 3D tissue on the ISS. Switch gravity from orbital microgravity to a 1 g Earth bench and watch the same culture sediment to the chamber floor and flatten under its own weight instead of self-assembling into a round construct — the real reason spaceflight biomedical research exists for regenerative medicine.
