[Study on effect of danshensu in directional differentiation of mesenchymal stem cells into neuron-like cells]
Objective:
To study the effect of Danshensu (DSS) on directional differentiation of mesenchymal stem cells (MSC) into neuron-like cells.
Methods:
MSC were separated from bone marrow with density gradient centrifugation, wall sticking screening and amplified in vitro. Flow cytometry was used to monitor the expression of surface antigens. DSS contained in non-serum L-DMEM was used to induce differentiation of MSC to neuronlike cells, and the effect of DSS when different concentration and acting time used was explored. And levels of neuron-specific enolase (NSE), neurofilament protein (NF-M), nestin, and expression of glial fibrillary acidic protein (GFAP) were measured by immunohistochemical method.
Results:
After being propagated and amplified in vitro, MSC were positively expressed for CD29, CD44, CD166, and negatively expressed for CD14, CD34, CD45, HLA-DR. After induction of DSS, MSC exhibited the typical form of perikaryon with pyknotic cell body and prominence projected like that of neuron. These cells were positively expressed in NSE, NF-M and nestin, and negatively expressed in GFAP.
Conclusion:
DSS could induce differentiation of MSC to neuron-like cells in vitro, the action is concentration- and time-dependent.
