Fig. 2From: Tissue catabolism and donor-specific dexamethasone response in a human osteochondral model of post-traumatic osteoarthritisPrincipal component analysis of media and tissue proteomes. PCA was performed on filtered and imputed proteomic data for batch-corrected media samples (A, B) and DNA-normalized tissue samples (C, D). N, no treatment; D, Dex alone treatment; IC, injury and cytokine treatment; ICD, injury, cytokines, and Dex. Percentages on axes represent percent variance explained by that principal componentBack to article page
