Statistical analysis. A) PAM outcome: the graph shows the mean width of clusters depending on the number of zones included in the cluster. B) Silhouette width (clustering score) of each of the seven transcriptomic units chosen for the clustering using the best second score of the PAM algorithm. C) Dendrogram obtained for the clustering of the 12 zones by HAC algorithm. The blue line cuts the dendrogram to retrieve the 7 transcriptomic units. D) Graph of PAM outcome showing the mean width of clusters depending on the number of clusters for transcripts. E) Clustering score (silhouette width) obtained for transcripts corresponding to the second best score of the PAM. F) Heat map representation of the transcripts clustering obtained by HCL algorithm. The blue line at the top cuts the dendrogram to show the 7 transcriptomic units and the green line on the left cuts the dendrogram to retrieve the 4 clusters of transcripts. (Relative expression level: yellow = high, blue = low; white = missing values). T: Testis, VE: Vas efferens, E0 to E8/9: nine epididymal zones, PC: Proximal caput, MC: Median caput, DC: Distal caput, VD: Vas deferens.
