====== miR 29c ====== Using a quantitative [[miR 29c]] reporter, Bier et al., demonstrated that the PL-[[MSC]] effects were partly mediated by the transfer of exosomal miR-29c. Intramuscular transplantation of PL-MSCs in mdx mice resulted in decreased creatine kinase levels. PL-MSCs significantly decreased the expression of [[TGF]]-β and the level of [[fibrosis]] in the diaphragm and cardiac muscles, inhibited inflammation and increased utrophin expression. In vivo imaging analyses using MSCs labeled with gold [[nanoparticle]]s or fluorescent dyes demonstrated localization of the cells in the muscle tissues up to 3 weeks post treatment. Altogether, these results demonstrate that PL-MSCs and their secreted exosomes have important clinical applications in cell therapy of DMD partly via the targeted delivery of exosomal miR-29c ((Bier A, Berenstein P, Kronfeld N, Morgoulis D, Ziv-Av A, Goldstein H, Kazimirsky G, Cazacu S, Meir R, Popovtzer R, Dori A, Brodie C. Placenta-derived mesenchymal stromal cells and their exosomes exert therapeutic effects in Duchenne muscular dystrophy. Biomaterials. 2018 May 3;174:67-78. doi: 10.1016/j.biomaterials.2018.04.055.

The miR-29c levels were positively correlated with patient outcomes. Our data suggest miR-29c may be potential therapeutic targets for glioma treatment ((Xiao S, Yang Z, Qiu X, Lv R, Liu J, Wu M, Liao Y, Liu Q. miR-29c contribute to glioma cells temozolomide sensitivity by targeting O6-methylguanine-DNA methyltransferases indirectely.
