Fig. 8From: Germ cell and tumor associated piRNAs in the medaka and Xiphophorus melanoma modelsDendrogram, based on the abundance relative to U6 of the selected piRNAs. Using only these three piRNAs it is possible to separate low malignant tumors (XE, FM) and HP from high malignant tumors (IM, UM) and testes. Skin, oxidized testis and ovary are clustered in one distinctly separated groupBack to article page
