Materials and Methods: In this experimental study, MACS kit was used to isolate CD133+ cells of umbilical cord blood. Further, the effect of two drugs of thalidomide and sodium butyrate were separately and combined studied on the induction of quantitative expression of β-globin and γ-globin genes in erythroid precursor cells derived from CD133+ stem cells in-vitro. For this purpose, the technique SYBR green Real-time PCR was used.
Results: Flow cytometry results showed that approximately 95% of purified cells were CD133+. Real-time PCR results also showed the increased levels of γ-globin mRNA in the cell groups treated with thalidomide, sodium butyrate and combination of drugs as 2.6 and 1.2 and 3.5 times respectively, and for β-globin gene, it is respectively 1.4 and 1.3 and 1.6 times compared with the control group (p<0.05).
Conclusion: The study results showed that the mentioned drug combination can act as a pharmaceutical composition affecting the induction of fetal hemoglobin expression in erythroid precursor cells derived from CD133 + cells.
