MicroRNA profiling in Mesenchymal Stromal Cells: the tissue source as the missing piece in the puzzle of ageing
We compare miRNA profiling  in two cell populations of mesenchymal stromal cells focusing on senescence-related changes: Human Dental Pulp Stromal Cells (hDPSCs) and human Periosteum-Derived Progenitor Cells (hPDPCs). After these cells were harvested, total RNA extraction and whole genome miRNA profiling was performed, and DIANA-miRPath analysis was applied to find the target/pathways. Our finding is consistent with the idea that the embryological origin influences cell behavior and the ageing process. Moreover, the two populations activate different downstream mechanisms. Our study strengthens the hypothesis that ageing is driven by numerous mediators interacting through an intricate molecular network, which affects adult stem cells self-renewal capability. Overall design: hDPSCs and hPDPCs miRNA profiling
