Fig. 4 — Piezoresistive and immunohistological results from (A) Patient 3 and (B) Patient 7. Upper left: Sensor responses from epithelial tissue. Upper right: Sensor responses from stromal tissue. Bottom Left: Percentage change in sensor voltage versus index (z-position). Bottom right: Histology and biomarker statuses of the ROIs. Tissue cores were stained with H&E, P63(brown)/SMA(red), ER and PR.
