Fig. 2From: Genome-wide DNA methylation study of hip and knee cartilage reveals embryonic organ and skeletal system morphogenesis as major pathways involved in osteoarthritisHierarchical clustering and heat map of hip OA, knee OA, and OA-free controls*. *Top: Cluster dendogram was created using the genome wide information; Bottom: Heat map shows the top 800 CpG sites with the most variation across hip OA, knee OA, and OA-free hip cartilage samples. Rows represent CpG sites. Columns represent samples. Dark blue indicates hypermethylation and light blue/white indicates hypomethylationBack to article page
