Expression of CLDN18.2 in primary gastric tumors and LN metastases.
- Intra-individually matched pairs of samples from a patient with strong CLDN18.2 expression in both the primary tumor (a-c) and corresponding lymph node metastasis (d-f) at three different magnifications.
- The graph depicts the distribution of CLDN18.2 staining intensities in tumor cells from patient samples of primary tumor and LN metastases. CLDN18.2 staining intensity in tumor cells from each tissue sample analyzed were classified as 1+, 2+, and 3+ CLDN18.2 reactivity and are shown.
CLDN18.2, claudin 18.2; LN, lymph node.
*Indicates normal stomach mucosal epithelium expressing CLDN18.2.
