Fig. 6From: H3K27me3 demethylases regulate in vitro chondrogenesis and chondrocyte activity in osteoarthritisThe impact of transforming growth factor (TGF)-β treatment on histone 3 lysine 27 trimethylation (H3K27me3) levels in human articular chondrocytes (HACs). H3K27me3 staining (green) in HACs following 1-h treatment with TGF-β or TGF-β plus GSK-J4.
