When the LPS concentration increased to 4 μg/mL, cell viability significantly decreased ( p < 0.05); at 8 μg/mL, the decrease was highly significant ( p < 0.01).
When the LPS concentration increased to 4 μg/mL, cell viability significantly decreased ( p < 0.05); at 8 μg/mL, the decrease was highly significant ( p < 0.01).
Notably, when cells were incubated with 2 μg/mL LPS, a decreasing trend in cell viability was observed, although no significant difference was found ( p > 0.05).
