| Research Abstract |
It was found that a lot of miRNAs were up-regulated when the subcutaneous adipose-derived stem cells (ASC) differentiated into brown-like adipocytes. Although these miRNAs may be involved in modulating ASC function, up-modulations of these miRNAs did not appear to affect ASC differentiation. In addition, we succeeded to obtain the novel monoclonal antibodies specifically responsible to ASC. Furthermore, we also applied the iontophoresis to noninvasive transdermal delivery of functional nucleic acids, and succeeded the silencing of the endogenous gene expression and activation of immune response in vivo. According to this study, it was suggested that ASC differentiation into brown-like adipocyte might be regulated by not only miRNAs but also unknown factors. Thus, the ASC specific antibodies and the delivery technology established by this study were helpful for the further investigation to clarify the molecular mechanisms of ASC function.
