“…The differentiation of stem cells is conventionally controlled by soluble cues; that is, the use of defined culture media containing multiple growth factors (e.g., bone morphogenetic proteins, insulin, peroxisome proliferator-activated receptor γ) and biomolecules (e.g., dexamethasone, ascorbic acid, glycerophosphate) [ 10 , 11 , 12 , 13 , 14 ]. However, recent findings suggest that biophysical cues, such as the physicochemical characteristics of the underlying substrate, to which the cells attach and actively interact with as they grow, can also play key roles in steering the transformation of MSCs into specific cell types [ 15 , 16 , 17 , 18 ].…”
