HucMSCs-exosomes promote cell proliferation in vitro. (a) HucMSCs-exosomes promote cell proliferation in a dose- and time-dependent manner. Results were shown as mean ± SD (). , , and compared to control group. (b) Western blotting analysis of phosphorylated ERK1/2 in cells treated with 800 μg/mL hucMSCs-exosomes as indicated. (A) H9C2(2-1); (B) HL-7702; and (C) NRK-52E.
