• We evaluated the differentiation capacity of BMSCs into PGCs using SMF (4 mT) and BMP-4 (25 ng/ml).
• The rate of differentiation was investigated using the Real Time-PCR method and ICC reaction.
• Our results showed that the combination of SMF with BMP4 exaggerates the differentiation rate.
This investigation was performed to evaluate the differentiation capacity and alteration in genes expression patterns during in vitro differentiation of bone marrow stem cells into primordial germ cells using static magnetic field (4 mT) and BMP-4 (25 ng/ml). The rate of differentiation was investigated using the Real Time-PCR method for tracing expression of differentiation markers (Oct-4, Nanog, C-Myc, Fragilis, Mvh and Stella). Then, immunocytochemical reaction was carried out for detection of marker proteins (Oct4 and Mvh). Increasing of the exposure time of the 4 mT SMF (24 and 48 h) and treatment time with 25 ng/ml BMP4 (48 and 96 h) indicated a marked decrease in expression of pluripotency genes (Oct-4, Nanog and C-Myc) and Oct4 protein and increase in primordial germ cell-specific genes (Fragilis, Mvh and Stella) and Mvh protein compared with the control group. Final results showed that in a synergistic manner, the combination of SMF with BMP4 exaggerates the differentiation potential of BMSCs to PGCs by activating the MAPK pathway and altering the Ca2+ concentration.
