Mechanical Strain Regulates Osteogenic and Adipogenic Differentiation of Bone Marrow Mesenchymal Stem Cells

Figure 5

Mesenchymal stem cells (MSCs) under 10 days of unstrained (a) and strain-stimulated (b) conditions in adipogenic medium; the cells are stained with oil red O. (a) Numerous intracellular lipid droplets (colored red) formed in the unstrained group. (b) Few intracellular lipid droplets formed in the strain-simulated group.
