Figure 7. BMSC-exosomal miR-512-5p inhibits tumor growth in vivo. (A) Effect of BMSC-exosomal miR-512-5p as determined by HE in nude mice. (B) JAG1 and Ki-67 expression as determined by IHC. (scale bar = 50 μM) (C) Tumor growth as determined by bioluminescence imaging. after treatment with PBS or BMSC-derived exosomes. (D) Overall survival of nude mice receiving treatment was determined by Kaplan-Meier analysis. (n = 15, respectively). (*p = 0.0184, comparing the BMSC-Control-Exo group with the PBS group, #p = 0.0036, comparing the BMSC-miR-512-5p-Exo group with the PBS and BMSC-Control-Exo groups, Log-Rank test).
