[Objective] To compare the biological characteristics of neuron-like cells from rat mesenchymal stem cells (MSC) induced by β-mercaptoethanol (BME) and basic fibroblast growth factor (bFGF) respectively. [Method] BME and bFGF were added to rat MSC respectively for 9 h and 5 days. The neuron-like cells from MSC with the neuron specific protein NF200 were identified using immunofluorescence. The gene expression of NF were analyzed using RT-PCR and the protein expression of NF200 were analyzed using Western blotting. [Results] MSC induced by BME appeared morphology change in an hour and the neurite can be seen at six hour. Some cell bodies became lighter and died. MSC induced by bFGF had neurite in the third day, and appeared network structure in the fifth day, then cells died in the seventh day. At the same time, The result of immunofluorescence showed the NF200 expression of neuon-like cells induced by two ways were beth positive, but MSC induced by bFGF were stronger than those induced by BME. The results of RT-PCR and western blotting were same as that of immunofluorescence. [Conclusion] Both bFGF and BME can induce rat MSC to neuron-like cells, but the neuon-like cells induced by bFGF were more like real neurons in morphology and expression of neuron specific protein and mRNA.

Pdx-1, an important transcription factor highlighting in the early pancreatic development,islet functions and pancreatic disorders, needs to be more investigated in zebrafish, and siRNA is still seldom applied in zebrafish embryo-related research.Our aim was to explore the role of pdx-1 in pan-creatic development of zebrafish embryos by using siRNA approach. Microinjection, reverse tran-scriptase-PCR (RT-PCR), in situ hybridization and immunofluorescent staining were used in this re-search, and the morphology of the islet in normal zebrafish embryos, and in those treated with the siRNA specific to pdx-1 (siPDX-1) or siGFP was observed and compared. The expression of pdx-1 was detected in the stages of 1-cell, 2-cell, 4-cell, 8-cell, 16-cell, 16-hour by RT-PCT. The in situ hy-bridization and immunofluorescent staining results showed that siPDX-I disturbed the formation of the islet in zebrafish embryos. Pdx-1 played multiple roles in maintaining the phenotype of the islet during embryogenesis in zebrafish.

AIM: To analyze neuron-related gene expression before and after mesenchymal stem cells (MSCs) differentiating into neuron-like cells. METHODS: MSCs were induced to neuron-like cells with ?-mercaptoethanol. Before inducement and at 8 h after inducement, the total RNA was extracted, then the expression of microtubule-associated protein-2 (MAP-2), growth-associated protein-43 (GAP-43), NSE, nestin and neurofilament (NF) mRNA were detected with RT-PCR. RESULTS: NSE mRNA expressed before and after inducement, MAP-2, GAP-43, nestin and NF mRNA only expressed after inducement. CONCLUSION: The differentiation of MSCs into neuron-like cells may be related to MAP-2, GAP-43, nestin and NF expression. [
