【 摘 要 】
Gravity is an omnipresent force on Earth, and all living organisms have evolved under the influence of constant gravity. Mechanical forces generated by gravity are potent modulators of stem cell based tissue regenerative mechanisms, inducing cell fate decisions and tissue specific commitment. A novel mechanical unloading investigation assessed the formation, morphology, and gene expression of embryoid bodies (EB), a transitory cell model of early differentiation. After 15 days of spaceflight, the mechanotransduction-null EB cells showed upregulated proliferative mechanisms while differentiation cues were silenced.
