In SCID Mice with Transplanted Joint Tissues from Rheumatism Patients, a Model Mice of Human Rheumatoid Arthritis, Anti-human Fas Antibody (R-125224) Distributes Specifically to Human Synovium

Purpose We investigated the tissue distribution of a humanized anti-human Fas monoclonal antibody, R-125224, in SCID mice transplanted with synovial tissues from patients with rheumatoid arthritis (SCID-HuRAg mice). The binding kinetics of R-125224 was also determined, using isolated human synovial cells.
