CNS disease diminishes the therapeutic functionality of bone marrow mesenchymal stem cells.

ABSTRACT: Mesenchymal stem cells (MSCs) have emerged as a potentially powerful cellular therapy for autoimmune diseases including multiple sclerosis (MS). Based on their success in treating animal models of MS like experimental autoimmune encephalomyelitis (EAE), MSCs have moved rapidly into clinical trials for MS. The majority of these trials use autologous MSCs derived from MS patients, although it remains unclear how CNS disease may affect these cells. Here, we report that bone marrow MSCs derived from EAE mice lack therapeutic efficacy compared to naïve MSCs in their ability to ameliorate EAE. Treatment with conditioned medium from EAE-MSCs also fails to modulate EAE, and EAE-MSCs secrete higher levels of many pro-inflammatory cytokines compared to naïve MSCs. Similarly, MSCs derived from MS pat
