Fig 2: Immunostaining of paraffin-embedded cells expressing markers CK8, CK5, and p63. Normal and cancer cells were plated for 48 to 72 hours and stained with basal and luminal markers (AR, CK8, and p63). The whole slide was scanned with the Vectra system. PC3 and LNCaP cells served as controls. AR and p53 were undetectable or weak, respectively (data not shown). Magnification 20×.
