(H) Correlation between clinical metastatic staging and SOX9 protein across the TMA of 142 cases of human medulloblastoma. The SOX9 protein levels were determined by IHC in Figure 3F. Tumors with SOX9 protein level frequently presented (p=0.038, Fisher's exact test,) with the M3 metastatic staging, spread to the spinal cord (red bars). Analysis was carried out by comparing patients with high SOX9 protein rank (Rank 5-7) versus patients with low SOX9 protein rank (Rank 1-3).
