â¢MiRNA expressions of UCMSCs and CBMSCs were compared for the first time.â¢A bioinformatics model unveiled miRNAs' regulation network.â¢Functional analysis identified different therapeutic potentials of UC- and CB-MSCs.
Human mesenchymal stem cells (MSCs) derived from both umbilical cord (UC) and cord blood (CB) share similar characteristics, and their differences are largely unknown. Besides the significant difference in cell morphology, differentiation ability and development processes of the two different origin MSCs, a different expression pattern of microRNAs between the two kinds of MSCs was also obtained. By comprehensively annotating the differently expressed global microRNAs (miRNAs), a series of biological pathways were predicted. We found that miRNAs significantly repressed insulin signaling in UCMSCs, while neural related processes were more repressed in CBMSCs. Particularly, TGF-β and Notch signaling were differently activated in both MSCs, unveiling their distinct angiogenesis potentials. Taken together, this study illustrates that MSCs from UC and CB display distinct properties, which indicates different potentials for clinical usage.
