Wnt-Early^Ex and Wnt1-Late^Ex tumors share features with different normal mammary cell types. (A) Cd49f/Epcam FACS profile of a representative Wnt1-Early^Ex tumor. (B) FACS population frequencies of Wnt1-Early^Ex tumors as measured from four independent primary tumors. Each measurement is represented as a cross. The error bars represent 1 s.d. (C) Cd49f/Epcam FACS profile of a representative Wnt1-Late^Ex tumor. (D) FACS population frequencies of Wnt1-Late^Ex tumors as measured from four independent primary tumors. Each measurement is represented as a cross. The error bars represent 1 s.d. (E) First two principle components of FACS-sorted Wnt1 tumor gene expression profiles.
