Expression of p38 isoforms in degenerated NP in situ.
(A) NP cells, marked with CD24 (red), express p38 α, β, δ but not γ isoforms (green) analyzed by Immunofluorescence staining. Bar = 50 μm. (B) a few macrophage in degenerated NP, marked with CD11b (red), express p38 α, γ, δ but not β isoforms (green). Bar = 5 μm. (C) percentage of CD24 postive NP cells express p38 α or β or γ or δ in degenerated NP samples (n = 150, *P < 0.05). (D) percentage of CD11b positive cells co-stained with p38 α or β or γ or δ in degenerated NP samples (n = 150, *P < 0.05).
