Figure 1 |. Zeb1 expression in tri-PyMT primary tumours.

a, b, Primary tumours of the orthotopic tri-PyMT model were stained with an anti-Zeb1 antibody. Representative images show that Zeb1 signals are only detected in GFP⁺ cells, not in RFP⁺ cells (as indicated by arrows in a, and quantified in b). c, Zeb1 is also expressed by stromal cells, which do not exhibit any GFP or RFP.
