摘要

Retinoic acid (RA) has an important role in nervous system development; exogenous RA could induce stem cells towards neural lineage cells. However, the miRNA regulation mechanism and biological process of this induction require further exploration. In this study, using high-throughput sequencing results, we evaluated the microRNA profiles of neurally differentiated adipose-derived mesenchymal stem cells (ASCs), summarized several crucial microRNAs that profoundly contributed to the differentiation process, and speculated that several miRNAs were likely to mimic RA or other factors to induce the neuronal differentiation of stem cells. The GO terms and KEGG PATHWAY in the DAVID tool were used to elucidate the biological process of RA induction. Finally, we described a network for clarifying the relationship among the miRNAs, target genes and signaling pathways. These findings will be beneficial for understanding the induction mechanism and supporting the application of RA in stem cell transformation. (C) 2017 Published by Elsevier Inc.
