Decreased Sox2 expression in neural stem/progenitor cells following FoxM1 depletion. A, schematic diagram describing the experimental procedure. B, ERT2-Cre FoxM1fl/fl neural stem/progenitor cells were treated with vehicle or 50 nmol/L 4OH-tamoxifen treatment for 4 days after being dissociated into single cells. mRNA levels of FoxM1, Sox2, and Bmi1 were detected by qRT-PCR. Wild-type neural stem/progenitor cells with same treatment were used as control. The mRNA levels were normalized to mouse cyclophilin mRNA, and the vehicle control groups were set to 1-fold. C, immunoblot showing the expression of FoxM1, Bmi1, Sox2, and Nestin of ERT2-Cre FoxM1fl/fl neural stem/progenitor cells treated with vehicle or 50 nmol/L 4OH-tamoxifen. β-actin was used as loading control.
