“…101,102 In an inflammatory environment, MSCs secrete factors which cause multiple anti-inflammatory effects and influence matrix turnover in synovium and cartilage explants. 103 MSCs have also been revealed as robust sources of TIMP-mediated MMP-inhibition, capable of protecting the perivascular niche from high levels of destructive MMPs, even under pathological conditions. 104 Due to their potential to modulate the local microenvironment via anti-inflammatory and immunosuppressive functions, MSCs have an additional advantage for allogeneic application (Fig.…”
