Abstract

The reactivity of a mAb (M16) raised against a small cell lung carcinoma line is described. M16 identifies a surface antigen expressed on cells of neuroectodermal origin following activation, as well as neoplastic transformation. M16 antigen expression is increased on retinoblastoma and neuroblastoma cell lines upon 'in vitro' stimulation and it is induced 'in vivo' on glial cells activated following brain injury. Furthermore, glial tumors show levels of M16 molecule expression increasing with the degree of malignancy, and in a retinoblastoma cell line, the expression of M16 was inversely related to the level of HLA-Class I and N-CAM antigens. The M16 antigen may represent a marker of both activation and neoplastic progression for neuroectodermal cells.
