From: Short Link N promotes disc repair in a rabbit model of disc degeneration
Proteoglycan content in intervertebral discs (IVDs) treated with short link N (sLN). After 12 weeks rabbits were sacrificed and IVDs were extracted and dissected into nucleus pulposus (NP) and annulus fibrosus (AF) tissues. Glycosaminoglycan (GAG) content was taken as a measurement of proteoglycan in the NP and AF. Means ± SEMs. Analysis of variance and post hoc Tukey’s multiple comparisons test was used to compare all groups. Comparison between saline and sLN to non-punctured discs, *p < 0.05, **p < 0.01; n = 3–7
