Effect of naringin on TNF-α-induced human NP cells. (a) Chemical structure of naringin. (b) Identification of human NP cell marker CD24 by flow cytometry. (c) CCK-8 results of human NP cells treated with different concentrations of naringin contain 0.1% DMSO for 24 h. (d) CCK-8 results of naringin pretreated human NP cells induced by TNF-α for 24 h. The data represent the means ± SD. Significant differences between groups are indicated as ^∗p < 0.05, ^∗∗p < 0.01, and ^∗∗∗p < 0.001, n = 3.
