Human Umbilical Cord Mesenchymal Stem Cell-Derived Extracellular Vesicles Promote the Proliferation of Schwann Cells by Regulating the PI3K/AKT Signaling Pathway via Transferring miR-21
Figure 4
hUCMSC-EVs promoted the proliferation of Schwann cells in vitro. (a) CM-Dil-labeled hUCMSC-EVs are internalized by RSC96 cells, scale bar: 20 μm. (b) The proliferation activity of RSC96 cells by CCK-8 assay. (c, d) The proliferating ability of RSC96 cells by colony-forming assay. Data are expressed as the , , vs. control (medium without EVs). (e) Western blot analysis of the protein expression of p-PI3K, PI3K, p-AKT, and AKT in Schwann cells.
