Disclosed is a method for inducing repair of a joint tissue in a mammal
includes the steps of removing a sample of synovial membrane from a joint
of the mammal, isolating type B synoviocytes from the membrane to yield a
suspension of enriched type B synoviocytes, and introducing the
suspension into an injured joint of the mammal as well as medical devices
containing enriched synoviocytes and kits for producing such enriched
cell populations.
