Figure 2. LM-exosomes increase cell viability and cell motility in HOC313-P cells.
(a) HOC313-P cells were treated with PBS or LM-exosomes, and the effect of exosomes on cell growth was determined using an in vitro WST-8 assay at the indicated times. (b) Western blot analysis of EGFR, ERK and AKT and their phosphorylation status is shown in HOC313-P cells treated with LM-exosomes for the indicated amounts of time. (c and d) Cell migration was assessed by Transwell migration assay (c) and cell invasion was assessed by Transwell invasion assay (d) in HOC313-P cells treated with either PBS or LM-exosomes. Experiments were performed in triplicate. (Bars, SD). Student’s t-test was used for statistical analysis; asterisks represent P < 0.05 versus each control transfectant.
