Abstract

Objective

To study the effects of recombinant neuritin expressed by Pichia pastoris GS115 on the senescence, apoptosis, proliferation, and migration associated with rat bone marrow-derived mesenchymal stem cells (BMSCs).

Results

Recombinant neuritin was purified by Ni-affinity chromatography and identified by western blot and MALDI-TOF spectrometry. The effects of recombinant neuritin on senescence, apoptosis, proliferation, and migration of rat BMSCs WERE investigated. β-Galactosidase staining indicated that recombinant neuritin administration significantly inhibited BMSCs senescence at 1 μg neuritin/ml. Additionally, recombinant neuritin reduced the number of apoptotic cells at the early stage according to Annexin V/propidium iodide staining and inhibited cell proliferation according to MTT assay results. Moreover wound healing assay results showed that recombinant neuritin promoted BMSCs migration in the neuritin-treatment group.

Conclusion

Recombinant neuritin affects the senescence, apoptosis, proliferation, migration of rat BMSCs. Our findings offer insight into neuritin function outside of the nervous system.
