The Impact of Simulated and Real Microgravity on Bone Cells and Mesenchymal Stem Cells

Table 1

Comparative methods of 3D cell culture systems using simulated 𝜇𝑔.

Device		Working principle
Free fall machine	FFM	Free fall for 800 ms, “bounce” of 20 g for 50 ms
Levitating magnets	LM	A high gradient magnetic field prevents sedimentation
2D-clinostat		Rotation along one axis
Random positioning machine	RPM	Two frames with randomized movement
Rotating wall vessel	RWV	Constant rotation prevents cells from settling
