Effects of neuritin on the migration, senescence and proliferation of human bone marrow mesenchymal stem cells.

Neuritin is a neurotrophic factor associated with neuroplasticity. Most studies on neuritin focus on the nervous system; however, there has been no comprehensive evaluation of neuritin in non-neuronal cells. In this study, we screened 11 cell lines and found that neuritin was not expressed in bone marrowderived mesenchymal stem cells (BMSCs). Neuritin-expressing BMSCs were obtained by transfection. In the neuritin-expressing BMSC model, we observed significantly greater cell migration and improved anti-senescence protection, in addition to reduced proliferation and viability. In conclusion, neuritin not only plays an important role in the nervous system but also has an effect on the migration, senescence, proliferation, and viability of stem cells. This study provides a theoretical basis for understanding the function of neuritin.
