UNASSIGNED: The aim of the present study was to examine the microRNA (miRNA or @entity696 ) expression profiles during the chondrogenic differentiation of @entity1 adipose  -derived stem cells (hADSCs) and identify the potential mechanisms through which miRNAs may affect the process of chondrogenesis. hADSCs were isolated and cultured. The expression levels of chondrogenic markers was detected by FACS analysis and immunohistochemistry. The miRNA expression profiles were then obtained through a miRNA array and confirmed through northern blot analysis. Putative targets of the miRNAs were predicted and validated through a luciferase reporter assay. The comparison of hADSCs following the induction of chondrogenic differentiation with undifferentiated hADSCs revealed 20  miRNAs that were differentially expressed by at least 2  -fold, and these miRNAs included 12  upregulated miRNAs and 8  downregulated miRNAs. Northern blot analysis further con   rmed the miRNA expression levels. Of these miRNAs, the expression of @entity696  -490  -5p was gradually downregulated following the induction of chondrogenic differentiation. The overexpression of @entity696  -490  -5p increased the expression of the chondrogenic markers, collagen, type  II, alpha  1 ( @entity794 ), @entity32099 ( @entity32099 ) and aggrecan. Furthermore, it was confirmed that @entity696  -490  -5p directly targets bone morphogenetic protein receptor type  2 ( @entity3823 ). In conclusion, in this study, we identified a set of miRNAs that may play key roles in the regulation of the chondrogenic differentiation of hADSCs. Our results may provide a basis for the further investigations into the molecular mechanisms of action of miRNAs in hADSC chondrogenesis.
