Expression Pattern of Neuronal Markers in PB-MSCs Treated by Growth Factors Noggin, bFGF and EGF

Mesenchymal stem cells (mscs) have the ability to differentiate into neuronal like cells under appropriate culture condition. in this study, we investigated whether mscs derived from human peripheral blood (pbmscs) can differentiate into neuronal like cells by synergic effect of the growth factors egf, bfgf and noggin. for this purpose, the expression of five neuronal markers (nestin, β iii tubulin, nfm, map2 and nse) were evaluated in treated pb-mscs by sybr green real time pcr. the expression analysis showed a higher expression of β- tubulin and nfm in treated bp-mscs compared with untreated pb-mscs as a control group. the expression of nestin was also diminished in pb-mscs treated with noggin. this study suggested that the treatment of pb- mscs with noggin alongside with bfgf and egf might differentiate these cells into neuronal lineage cells. the obtained results could be further developed for useful applications in regenerative medicine.
