CELL surface components play a major role in the control of normal cell interactions and in the altered growth control and antigenic properties of malignant cells1. To characterise tissue-specific cell surface proteins we undertook an immunochemical study of the material released from cells by mild proteolytic treatment. Our studies have disclosed a fibroblast-specific cell surface and serum antigen in chicken2. The amount of this antigen is greatly reduced in chicken fibroblasts transformed by… CONTINUE READING
