Cluster analysis and Principal Component Analysis of all tooth germ samples. a Cluster dendrogram of tooth germ samples from different types and from different time points of the test and validation set. b Principal Component Analysis of tooth germ samples from different types and from different time points of the test and validation set. The figure shows the first (x-axis) versus the second (y-axis) versus the third (z-axis) principal component. The samples were analyzed according to the expressions of 591 detectable miRNAs using auto-scale method. First deciduous incisor (Di), deciduous canine (Dc), second deciduous premolar (Dpm), and deciduous molar (Dm). The miRNA expression was globally altered by types and temporal changes
