Divergent effects of distinct perivascular cell subsets for intra‐articular cell therapy in posttraumatic osteoarthritis

Intra‐articular injection of mesenchymal stem cells has shown benefit for the treatment of osteoarthritis (OA). However, mesenchymal stem/stromal cells at the origin of these clinical results are heterogenous cell populations with limited cellular characterization. Here, two transgenic reporter mice were used to examine the differential effects of two precisely defined perivascular cell populations (Pdgfrα + and Pdgfrβ + cells) from white...
