ABSTRACT
Bone marrow-derived mesenchymal stem cells (MSCs) have been demonstrated to be able to differentiate into neuron-like cell, but the precise mechanisms controlling this process are unclear. We report here that LY294002, a small molecule inhibitor of PI3K/AKT signal pathway, can inhibit proliferation and promote neuronal differentiation of MSCs after MSCs incubated with LY294002 for 6 and 12 h. RT-PCR results indicated that mRNA expression of α5ß1 integrin significantly increased in neuron-like cell from MSCs. Interestingly, neuron-like cells derived by this method adhere much more strongly than MSCs, which was related to the expression of α5ß1 integrin and FAK phosphorylation. However, these effects could be attenuated by LiCL or GSK-3ß-siRNA. Our results indicate that activation GSK-3ß signaling may be involved in MSCs proliferation, differentiation, and adhesion. Furthermore, this study demonstrates that small molecule regulators of PI3K/AKT signaling may be valuable tools for stem cell research aimed at treatment of neurodegenerative disease.
