Effects of EAS on the morphology of TNF-α-treated chondrocytes. Chondrocytes were treated with or without TNF-α, and with or without EAS, for 48 h, and a phase-contrast microscope was employed to detect the morphological alterations (magnification, ×200). EAS, electroacupuncture serum; TNF-α, tumor necrosis factor-α.
