Expression of SOX2. (a) Quantitative real-time PCR analysis of SOX2 mRNA expression in SP and MP cells. MP cells were used for the control, which was set as 1.0. Data are expressed as means±s.d. of relative values compared with MP cells. (b) RT-PCR using human cancer cells. Fetal brain was used as a positive control. Double distilled water (DDW) was used as a negative control. (c) RT-PCR using human adult tissues and human fetal tissues.
