Figure 5. The validation results of qRT-PCR. (A) Flag-tagged Msgn1 was introduced into 46C mESCs and the protein level of Flag-tagged Msgn1 was determined by Western blot. β-actin was used as a loading control. (B) qRT-PCR analysis of the indicated gene expression for the indicated time in mESCs and mESCs-derived EBs. Data represent mean±s.d. of three biological replicates. #p < 0.05 vs PB:Day 0. *p < 0.05, **p<0.01 vs PB-Mgsn1:Day 0.
