T2-weighted magnetic resonance imaging (MRI) nucleus pulposus (NP) area and MRI index. Contour segmentation of the midsagittal MRI for each disc outlined the NP as the region of interest. (Top) Average data for NP area and (Bottom) MRI index combining L2–L3, L3–L4, and L4–L5 (the treated discs) for each rabbit group are expressed as a percent of the time 0 value. Error bars represent standard error. BMP2, bone morphogenetic protein 2; TIMP1, tissue inhibitor of metalloproteinase 1.
