Figure 3. Pairs of primary breast cancer and lymph node metastases demonstrate different patterns of CEACAM5 expression.

Figure 3

Immunohistochemical stainings for CEACAM5 on paired primary breast cancers (P) and corresponding lymph node metastases (M) from a tissue microarray (TMA). Tumor pairs are ordered according to expression patterns marked by symbols: homogeneous expression (filled grey circle), heterogeneous expression (half-filled grey circle) and no expression (white circle). *marks tumors with a notably higher frequency of CEACAM5-positive cells within a pair. Bar, 25 μm.
