Fig. 6From: Modeling early changes associated with cartilage trauma using human-cell-laden hydrogel cartilage modelsGAG deposition in engineered cartilage constructs after traumatic impact. The DMMB assay was used to quantitate the GAG content in engineered cartilage constructs 1, 3 or 7 days after traumatic impacts or continuous IL-1β treatment. n = 12/group. #p < 0.0001; ***p < 0.001; **p < 0.01Back to article page
