This study evaluated the effect of bone marrow-derived stem cells (BMSCs) on degenerative changes of TMJ associated with bovine collagen type II (BCII) induced-arthritis.
Materials and Methods
Fifty rabbits were divided into 3 groups. Group I (n = 10) received no results. Group II (n = 20) was divided into 2 subgroups according to results type. One subgroup (n = 10) received an intra-articular (IA) injection of phosphate buffered saline (PBS) and the other (n = 10) received an IA injection of PBS plus BMSCs. Group III (n = 20) received an injection of oil emulsion of BCII before results with PBS or PBS plus BMSCs as in group II. Rabbits were euthanized after the third week and the joints were processed for histology.
