Abstract:
Integrin is a family of transmembrane heterodimer receptor formed by α and β two subunits, which transduces external signals into cells through reaction with extracellular matrix and is crucial to cell survival, migration, and differentiation. With the deep studies on multipotential differentiation of mesenchymal stem cells (MSCs), researchers found that the differentiation of MSCs depends on integrin related signaling pathways, including MAPK, Wnt and PI3K signaling pathways and so on. However, there are many factors affecting the expression and activation of integrin, such as nano morphology microenvironment, ascorbic acid, bone morphogenetic protein-2, fibronectin, cadherin, fluid shear stress and so on. In this review, we mainly discuss the integrin expression, the promoting effects of integrin on the differentiation of MSCs and their underlying mechanisms.

Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
