Stabilization of b-Catenin in the nucleus pulposus of tail IVD altered the expression of extracellular matrix and Wnt-related genes. (A) Experimental design/timeline of 4 mo bCAT cACT mice and the harvest of the tissues after 1 mo. Red “X” indicates tissue harvest. Letters on the right side of the “X’s” indicate the panels in the timeline. (B) Immunohistochemical stain for b-Catenin (brown stain, orange arrow) in the NP. (C) Quantification of b-Catenin-positive cells in the NP. (D) Gene expression of matrix and cell phenotype in bCAT cACT (n = 5) versus WT (n = 7) discs. (E) Gene expression of Wnt ligands are listed in decreasing delta CT value with the greatest baseline expression listed first. Scale bar: (B) 25 µm. NP: nucleus pulposus. Data are presented as mean + SD. bCAT cACT vs. WT; *p < 0.05.
