Pattern of fibronectin distribution in human lung cancer.

The pattern of fibronectin (FN) distribution in human lung cancer was studied by indirect immunofluorescent staining, and by the peroxidase-antiperoxidase method in a total of 60 surgical specimens. They comprised 8 small cell carcinomas, 4 large cell carcinomas, 19 squamous cell carcinomas, 28 adenocarcinomas, and 1 adenoid cystic carcinoma.
