Plant Exosomes As Novel Nanoplatforms for MicroRNA Transfer Stimulate Neural Differentiation of Stem Cells In Vitro and In Vivo.

Differentiation of bone marrow derived mesenchymal stem cells (BMSCs) into functional neural cells has been widely investigated for treating neural diseases. However, the limited neural differentiation of BMSCs remains a big challenge to overcome. Herein, for the first time, ginseng-derived exosomes (G-Exos) were demonstrated to have excellent efficiency in stimulating the neural differentiation of BMSCs by transferring the incorporated miRNAs to BMSCs efficiently.
