Abstract
Summary
Fluorescent antibodies prepared against extracellular particles from a continuous culture of cells derived from a monocytic leukemia stained JIII cells but not cells infected with Rauscher leukemia virus or simian sarcoma virus. These antibodies reacted with 38% of bone marrow preparations from patients with lymphoma, 26% of preparations from patients with nonmalignant blood disorders and 6% of preparations from patients with leukemia. Bone marrow films from patients with lymphoma over the age of 50 stained less frequently than those from patients under 50. These particles released from JIII cells are not antigenically related to two of the commonly studied oncornaviruses, but may be indicative of the etiology or disease process of lymphoma in young patients.
