Figure Lengend Snippet: BMSC-Fe 3 O 4 -SMF-Exos Mitigate Intracellular ROS in Irradiated BMSCs. ( a , c ) Intracellular total ROS levels in BMSCs were evaluated utilizing the 2′,7′-dichlorodihydrofluorescein diacetate (DCF-DA) fluorescent probe, accompanied by the relevant quantitative determination. ( b , d ) Superoxide anion (O 2 − ) production in irradiated BMSCs was monitored with the DHE fluorescent probe, and concurrent quantitative analysis was implemented. ( e ) The concentration of MDA in irradiated BMSCs was quantified. ( f , g ) The levels of SOD in irradiated BMSCs were measured at the 24 h and 48 h time points, separately. n = 3; (**) p < 0.01; (***) p < 0.001, and (****) p < 0.0001.
Article Snippet: Similarly, intracellular superoxide anion levels were measured using a Dihydroethidium (DHE) Superoxide Anion Fluorescent Probe Kit (G1904-100T, Servicebio, Wuhan, Hubei, China) in full accordance with the manufacturer’s instructions.
