Fig. 1From: A positive feedback loop between EZH2 and NOX4 regulates nucleus pulposus cell senescence in age-related intervertebral disc degenerationCaudal intervertebral discs (IVDs) of two-month-old (2 M) rats and ten-month-old (10 M) rats. a Cross section of caudal IVDs obtained from 2 M (left) and 10 M (right) rats. b H&E staining of caudal IVDs at different magnifications. c Micromagnetic resonance imaging (Micro-MRI) of caudal IVDs from 2 M and 10 M rats and T2 signal intensity of the nucleus pulposus (NP). The data are represented as the mean ± SEM (n = 9). **p < 0.01. H&E staining: hematoxylin and eosin stainingBack to article page
