Process of cell-free therapy from MSCs to target cells. In cell-free therapy, there is a method of transmitting exosome secreted from MSCs to target cells, and a method of selecting specific miRNA in MSCs, then synthesizing it in the formed mimic and delivering it to target cells. A transport is needed to deliver miRNA mimic to target cells in vivo. Generally, viral/non-viral carrier and targeted delivery are used.
