To obtain knowledge whether cancer progression was induced, we treated the cells 48 h after trypsinization with dexamethasone for 2, 6, 12 and 24 h, followed by western blot analysis of the pluripotency markers SOX2 and Notch1 and saw that dexamethasone rapidly induced the expression of both proteins (Figure 3f and Supplementary Figure S3e). Here, SOX2 is linked to cancer.
