Fig. 6From: Shock wave-induced ATP release from osteosarcoma U2OS cells promotes cellular uptake and cytotoxicity of methotrexateShock waves significantly stimulated U2OS cell uptake of Calcein and LY. The uptake of Calcein and LY following addition of KN62 (10 μM for 5 min) were determined and significantly reduced intake of Calcein and LY following addition of KN62 was observed. Data are mean ± SD, n = 3, ***p < 0.05, Student’s t-testBack to article page
