The effects of CoCl2 and H2S on the viability of 16HBE14o- cells were determined by CCK-8. (a) The viability of 16HBE14o- cells preconditioned with a series of CoCl2 concentration (0, 100, 200, 400, 600, or 1000 μmol/L). (b) The viability of 16HBE14o- cells treated with 400 μmol/L CoCl2 and NaHS in varying doses (0, 100, 200, 400, 600, or 1000 μmol/L) (mean± SD, n=4, ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001 versus control group, #p < 0.05, ###p < 0.001 versus hypoxia group).
