The colony formation assay indicated that PCa cells treated with 5 nM docetaxel and supplemented with AGD1-OE-PCSCs-exos formed more colonies than those with PCSCs-exos (1.85 ± 0.10 vs. 1.02 ± 0.10 in PC3; 1.74 ± 0.08 vs. 1.25 ± 0.09 in DU145), while fewer colonies formed with shAGD1-PCSCs-exos (0.29 ± 0.01 vs. 1.02 ± 0.10 in PC3; 0.34 ± 0.04 vs. 1.25 ± 0.09 in DU145) (Fig. 2G and H). Here, MIR100HG is linked to posterior cortical atrophy.
