(A) Viability of mature nucleus pulposus (MNP) and notochordal (NC) cells following 24-hour culture under control (atmospheric), low-, and high-pressure loading. (B) T (brachyury) gene expression relative to paired atmospheric control (y = 1). (C) MNP and NC cells labeled against vimentin (green) and cytokeratin 8 (red) counterstained with Hoechst (blue), scale bar = 20 µm (mean ± SD, N = 3) (For interpretation of the references to colours in this figure legend, refer to the online version of this article).
