Fig. 2. Phlpp1 is positively correlated with human intervertebral disc degeneration.

Fig. 2

a) Representative images of immunohistochemistry staining for Phlpp1 (red) in human IVDs with degeneration grade 1–5. Left: Phlpp1 stain in the NP, right: Phlpp1 stain in the AF. Arrows indicate positive cells. Neg.: negative control of Phlpp1 stain with primary antibody being replaced by negative control IgG. b+c) Quantification of staining for Phlpp1 and its correlation with b) degeneration grade and c) age. Expression of Phlpp1 was strongly correlated with the degeneration grade and to a lesser extent with age both in the NP and AF (n = 16)
