タイトル Cytokines regulate stemness of mesenchymal stem cells via miR-628-5p during periodontal regeneration.
ジャーナル J Periodontol
Abstract BACKGROUND:Cytokines play key roles in stimulating periodontal regeneration; however, their exact mechanisms of action remain unclear. Mesenchymal stem cells (MSCs) are multipotent cells that have self-renewal abilities and can differentiate into periodontal tissues such as bone, cementum, and periodontal ligaments following transplantation, like periodontal progenitor cells. Here, we used MSCs to identify the regulatory genes induced by periodontal regenerative cytokines.
METHODS:Human MSCs (hMSCs) were cultured under conditions of periodontal regenerative cytokine stimulation or silencing of undifferentiated hMSC transcription factors. To characterize the changes associated with periodontal regenerative cytokine-regulated microRNAs (miRNAs), miRNA, and mRNA expression was evaluated using miRNA arrays and quantitative real-time polymerase chain reaction, respectively. One of the identified miRNAs, miR-628-5p, was then overexpressed or suppressed in hMSCs during osteogenesis; the effect of these changes on osteogenesis was investigated.
RESULTS:Cytokine-stimulated MSCs showed characteristic miRNA profiles and mRNA levels of undifferentiated hMSC transcription factors ETV1, SOX11, and GATA6. Next, we silenced these transcription factors in MSCs and examined the miRNA profiles. The levels of miR-628-5p were decreased upon all cytokine treatments and were increased upon silencing of ETV1, SOX11, and GATA6. Overexpression of miR-628-5p suppressed osteogenesis; however, its inhibition enhanced OPN, ALP, OC, BMP2, and RUNX2 mRNA levels, and bone matrix mineralization, but not OSX mRNA or ALP activity.
CONCLUSIONS:miR-628-5p negatively regulates MSC stemness during periodontal regeneration. Periodontal regenerative cytokines act as miR-628-5p suppressors to support periodontal regeneration. Thus, selection of effective cytokines for different MSCs, based on miRNA profiling, is important for advancing regenerative therapies.
