Gene Ontology (GO) of MGUS, SMM and MM MSC contrasted to healthy individuals revealed contributed cell processes Representative overview of GO representing contributed processes such as skeletal system, cell communication or apoptotic processes in MGUS MSC. (A) Developmental processes, cell death, or mesenchymal cell differentiation were enriched in SMM (B) and in MM MSC processes such as DNA repair, mesenchyme development, or regulation of cell-matrix adhesion (C) were strongly enriched. For all GO terms, fold enrichment and P-values of overrepresented and underrepresented processes are given.
