Fig. 5 — a Epha2^+/+ mESCs were transfected with the indicated siRNAs, and EPHA2, OCT4 and SOX2 levels determined by immunoblotting. A non-specific band was used as a loading control. b Epha2 and Oct4 mRNA expression was determined by qRT-PCR following transfection of Epha2^+/+ mESCs with control or OCT4 siRNA. Data show mean ± SEM of four technical replicates (n = 4). c Pluripotency transcription factor-binding sites in Epha2 gene regulatory regions were extracted from CODEX mESC ChIP-SEQ data (http://codex.stemcells.cam.ac.uk). d Epha2^+/+ mESCs were transfected with the indicated siRNAs, and stimulated with 1 μg/ml clustered EFNA1 for 15 min. EPHA2 was immunoprecipitated using EPHA2 antibody, and pTyr and EPHA2 levels determined by immunoblotting. e EFNA1/B1 affinity purification from control, dasatinib-treated or siOct4-transfected mESCs. pTyr, EPHA2, OCT4 and ERK1/2 levels were determined by immunoblotting.
