Microgravity uncovers a developmental state transition on human osteoblasts. Upon simulated microgravity exposition human primary osteoblasts assume spindle-shape morphology reverting the mature phenotype and their specialized functions. A mature osteoblast cell loses levels of bone crystal deposit, osteogenic markers, and adhesive proteins, enhancing prior developmental state features (glycolysis, pre-osteoblast state marker, and cell protrusions), which in turn allows it to acquire motility properties.
