Effect of TXC on the death of TNF-α-injured OB-like cells. Compared with the TNF-α group, the TXC group exhibited a significantly decreased cell death rate of the injured OB-like cells. (A) Images were taken from three independent experiments and captured at a magnification of ×200. (B) Quantification of cell death analysis. For all groups, n=3. **P<0.01; ***P<0.001. TXC, Tougu Xiaotong capsule; TNF-α, tumor necrosis factor-α; OB, osteoblast; PI, propidium iodide.
