Effect and Mechanism of 808 nm Light Pretreatment of Hypoxic Primary Neurons

Figure 2

Effect of 808 nm LED light pretreatment with various power densities on cell viability in cultured neurons with 100 μM/L-CoCl2. Neurons were cultured in incubator at 37°C for 4 h, the culture medium was removed, and then 200 μL of DMSO was added after 10 min shaking before cell viability was measured. The power intensities chosen were 5, 10, 25, and 50 mW/cm2. Data are Means ± SEM. ** means that this group was highly significantly different from control group ( ). * means that this group has statistical difference with control group ( ).
