چکیده انگلیسی
Neural stem cells are a reliable resource in various neural tissue repair and neurodegenerative diseases. Increasing evidence has demonstrated that Suppressor of cytokine signaling proteins (SOCS) was involved in the nervous system development. The universality and diversity of SOCS also suggested their important roles in neurogenesis and nerve regeneration. In this study, we employed a lentiviral vector to investigate the impacts of overexpression SOCS1 on the proliferation and differentiation of rat-derived NSCs. Cells infected with LV-EGFP-SOCS1 showed a prominent increased cell number, diameter, and metabolic activity compared with other groups. Immunofluorescence analysis revealed the proportion of cells positive for microtubule associated protein-2 (MAP2) or myelin basic protein (MBP) was significantly increased in LV-EGFP-SOCS1 group while the proportion of glial fibrillary acidic protein (GFAP)-positive cells in LV-EGFP-SOCS1 group was significantly decreased compare to LV-EGFP and PBS group. Moreover, Western blot results were consistent with immunofluorescence results which indicated that overexpression of SOCS1 could promote neuronal and oligodendrocyte differentiations of NSCs but inhibit astrocyte differentiation of NSCs. In conclusion, our findings provided evidence that SOCS1 could promote the proliferation of NSCs and affect the differentiation of NSCs, providing a potential target for NSCs transplantation strategies.
