عنوان انگلیسی Direct Differentiation Of Human Primary Fibroblast Into Hematopoietic-Like Stem Cells; A New Way Without Viral Transduction
چکیده انگلیسی مقاله Objective: The aim of this study was to investigate the possibility of producing safe hematopoietic stem cells without the use of viral infectious agents that can be used in stem cell transplantation.
Materials and Methods: In this experimental study, after single layer cell formation, human primary fibroblast cells were
treated with static electromagnetic fields of 10 and 15 milli Tesla (mT) for 20 minutes each day for seven consecutive days. On the seventh day and immediately after the last radiation, the cells were added to the wells containing specific hematopoietic stem cell expansion media. After 21 days and colony formation, the cells belonging to each group were
evaluated in terms of the expression of CD34, CD38, and GATA-1 genes using quantitative real-time polymerase chain reaction (PCR), as well as surface marker expression of CD34 by flow cytometry.
Results: Exposure to 10 mT and 15 mT electromagnetic field increased the expression of CD34 and CD38 genes (P<0.05). This increase in gene expression levels were 2.85 and 1.84 folds, respectively, in the 10mT group and 6.36 and 3.81 folds, respectively, in the 15 mT group. The expression of the GATA-1 gene in the 10 mT and 15 mT groups was not significantly different from that of the control group (P<0.05). Electromagnetic waves caused a marked increase in the expression of the CD34 marker at the surface of reprogrammed cells. The rate of expression was about 42.3% in the 15 mT group and 23.1% in the 10 mT group.
Conclusion: The presence of human primary fibroblasts exposed to electromagnetic fields can increase the expression
of specific hematopoietic genes. This method can be suitable for reprogramming cells differentiated into hematopoieticlike stem cells and does not pose the risks of retroviral use.
