Figure 1From: Gene expression profiling of early intervertebral disc degeneration reveals a down-regulation of canonical Wnt signaling and caveolin-1 expression: implications for development of regenerative strategiesTypical macroscopic pictures and corresponding H&E sections of the applied classification. The notochordal cell (NC)-rich nucleus pulposus (NP) (A) contains NCs with a viable morphology organized in clusters; the mixed group (B) contains both NCs and chondrocyte-like cells (CLCs); and the CLC-rich group (C) contains solely CLCs embedded in a dense matrix.Back to article page
