Figure 1. SPARC protein expression in non-small cell lung cancer (NSCLC).

Figure 1

Paraffin-embedded sections were stained with SPARC antibody and counterstained with Mayer's hematoxylin as described in Materials and Methods. SPARC positive expression was defined as staining ≥ median staining, and negative expression was defined as staining < median staining. SPARC staining in the cytoplasm and stroma was brown. A, SPARC-positive squamous cell carcinoma; B, SPARC-negative squamous cell carcinoma; C, SPARC-positive adenocarcinoma; D, SPARC-negative adenocarcinoma.
