Figure S11 shows that scattered pro SP-C positive cells are present in distant metastasis in liver, pancreas, brain and kidney. Additionally in the kidney, Clara cell secretory protein (CCSP) positive tumor cells were detected (Figure S11). In the one case of a LKB1-mutant lung tumor that gave rise to liver metastasis, the metastasis scored negative for the mutation. Here, SCGB1A1 is linked to neoplasm.
