Rheumatoid synovial tissue cell proliferation was studied by incubating fresh synovial tissue samples with [3H]-thymidine in vitro. The samples were collected at operation from 7 rheumatoid patients. It was found that 0.9-4.9% of the total cell population, excluding the synovial lining cells, became labelled.
