(1) Representative images of nucleus pulposus tissue stained with (a–c) Safranin O/ fast green (FCF), (d–f) for XT-I, and (g–i) for GT-I in 6-month-old (a, d and g), 2-year-old (b, e and h) and 8-year-old (c, f and i) bovine IVD tissues (n=5; scale bar=100 μm). (2) Quantification of the XT-I and GT-I staining intensity in NP tissue. Data were normalized to the surface area and are represented as the mean±s.e.m. (n=5). * denotes significant differences between the different groups at P<0.05.
