Abstract/OtherAbstract:
Bone marrow mesenchymal stem cells (MSCs) are known to differentiate into neurons in vitro. However, the mechanism underlying MSC differentiation remains controversial. A recent analysis has shown that Notch signaling is involved in regulating the differentiation of MSCs. This study examines the potential mechanism of the differentiation of MSCs into neurons, and it considers the role of caveolin-1 in this process. We investigated neuron differentiation and Notch signaling by detecting the expression levels of microtubule-associated protein 2 (MAP-2), Neuron-specific Enolase (NSE), Notch-1, Notch intracellular domain (NICD) and hairy enhancer of split 5 (Hes5). We found that by down-regulating caveolin-1 during induction, MSCs were prone to neural differentiation and expressed high levels of neuronal markers. Meanwhile, the expression levels of Notch-1, NICD and Hes5 decreased. Our results indicate that down-regulation of caveolin-1 promotes the neuronal differentiation of MSCs by modulating the Notch signaling pathway.
