Extraction of nucleus pulposus cells from tuberculosis infected intervertebral discs. (A) The CT scan shows the nucleus pulposus destruction in sagittal and horizontal planes in ST patient. (B, C) The wound healing assays indicated that tuberculosis infection significantly reduced the migration ability of NPCs (n = 3, * p < 0.05, *** p < 0.001). (D) The CCK-8 assays indicated that tuberculosis infection significantly reduced the proliferation ability of NPCs (n = 3, ** p < 0.01, *** p < 0.001)
