Figure 5. Colorectal cancer exosomes induce the umbilicated spheroids formation in ccMSCs.
(A) Proliferation rate of cMSCs spheroids compared with that of ccMSCs ones, incubated with pCRCexo or mCRCexo for 72 h; (B) Measurements of the volume of ccMSC spheroids formed after the pCRCexo or mCRCexo treatment at 72 h respect to untreated ccMSCs (CTR). Statistical analysis were performed by unpaired Student t-test, between untreated cMSCs or ccMSCs (CTR) and +pCRCexo, CTR and +mCRCexo, +pCRCexo and +mCRCexo (**p≤ 0.005; ***p < 0.001). (C) CLSM images of ccMSCs spheroids untreated or treated with pCRCexo or mCRCexo for 72 hours.V-ATPase protein expression was reported in white, nuclei are reported in blue (DAPI). Scale bars, 20 μM.
