Abstract
Therapy with mesenchymal stromal cells (MSCs) has shown promise in inflammatory bowel disease-leveraging their immunosuppressive and regenerative properties. However, the potential immunogenic complications of allogenic MSCs sourced from different tissues raise concern. Thus, we assessed the fitness and functionality of autologous intestinal MSCs as a potential platform for cellular therapy. Mucosal biopsy-derived MSCs from Crohn's disease (n = 11), ulcerative colitis (n = 12), and controls (n = 14) were analyzed by microscopy and flow cytometry for doubling-time, morphology, differentiation potential, and immunophenotype. Gene expression, cell-subtype composition, along with surface marker and secretome changes after IFN-γ priming were measured by bulk and single-cell RNA sequencing coupled with a 30-plex Luminex panel. MSCs expanded ex vivo demonstrate canonical MSC markers, similar growth kinetics, and tripotency regardless of the patient phenotype. Global transcription patterns were similar at baseline though inflammatory bowel disease (IBD) rectal MSCs showed changes in select immunomodulatory genes. IFN-γ priming resulted in upregulation of shared immunoregulatory genes (particularly in PD-1 signaling) and overrode the transcriptional differences observed at baseline. Furthermore, MSCs secrete key immunomodulatory molecules at baseline and in response to IFN-γ including CXCL10, CXCL9, and MCP-1. Overall, MSCs from IBD patients have normal transcriptional and immunomodulatory properties with therapeutic potential and can be sufficiently expanded.
