title: Spontaneous esophageal carcinoma and epithelial cell line of an adult rhesus monkey.
abstract: A continuous epithelial cell line, 816A, was established from a lymph node of an adult rhesus monkey with metastatic esophageal carcinoma. These cells are characterized by the presence of desmosomes and a markedly heteroploid karyotype. At a relatively early culture age, electron microscopy showed both budding and extracellular type C virus. Antigen reactive with antisera to Mason-Pfizer monkey virus was observed by complement-fixation. The level of this antigen decreased with increased culture age. To our knowledge, the 816A cells represent the only established simian or human cell line of esophageal carcinoma origin.
