Exosomal ADAMTS9‐AS2 inhibits OSCC cell proliferation. ADAMTS9‐AS2 expression in (A) ADAMTS9‐AS2–overexpressing OSCC cells and (B) their corresponding exosomes by qRT‐PCR analysis. ***P < .001. C, Cell viabilities were evaluated after incubated with exosomes (10 μg/mL) in CAL‐27 and SCC‐9 cells by MTT. *P < .05; ***P < .001. D, Colony formation of OSCC cells with or without treatment of ADAMTS9‐AS2–expressing exosomes (left panel). Rates are shown as mean ± SD (right panel) from three independent experiments. *P < .05; **P < .01. Exos, exosomes
