Mechanical Stress Regulates Osteogenesis and Adipogenesis of Rat Mesenchymal Stem Cells through PI3K/Akt/GSK-3β/β-Catenin Signaling Pathway

Figure 1

Diagrammatic representation for cyclic mechanical stress generated by PBS drops. Parameters of mechanical stress consisted of frequency (Hz) (controlled by drops per second) and height (cm) (perpendicular distance from drip nozzle of PBS to cover glass).
