Fig. 3From: Modeling early changes associated with cartilage trauma using human-cell-laden hydrogel cartilage modelsCell metabolic activity in traumatized engineered cartilage constructs. Cell metabolic activity within engineered cartilage constructs impacted at 30% strain or treated with 10 ng/ml IL-1β was assayed by WST-8/CCK8 assays at 1, 3 and 7 days after treatment. n = 20/group, #p < 0.0001; ***p < 0.001Back to article page
