Fig. 2From: Tissue-aware RNA-Seq processing and normalization for heterogeneous and sparse dataPCoA analysis allows for grouping of subregions for greater power. Scatterplots of the first and second principal coordinates from principal coordinate analysis on major tissue regions. a Aorta, coronary artery, and tibial artery form distinct clusters. b Skin samples from two regions group together but are distinct from fibroblast cell lines, a result that holds up (c) when removing the fibroblastsBack to article page
