title: Establishment of a cell line producing basement membrane components from an adenoid cystic carcinoma of the human salivary gland.
abstract: A new cell line has been established from an adenoid cystic carcinoma arising in the submandibular gland of a 63-year-old woman. The cultured epithelial-like cells grew vigorously and adhered together to form a sheet. Immunohistochemical stainings for type IV collagen, laminin and fibronectin were clearly positive in the intercellular matrix and on the surface of the culture cells. Chondroitin 6-sulfate proteoglycan and heparan sulfate were also detected. Ultrastructural studies showed that the cells had abundant rough endoplasmic reticulum and a well-developed Golgi apparatus. Rough endoplasmic reticulum near the cell surface was markedly dilated, and contained material of low electron density. This cell line would be useful for biological and biochemical studies on the mechanisms by which the stromal component is formed.
