PCA reveals differences between healthy adult and cord blood repertoires. PCA was applied to V-J gene frequency for three healthy donors (HIP1–3) and three cord blood donors (CORD1–3). X and Y axes show principal components 1 and 2, and the percent variation explained by each component is shown in parenthesis. Black circles show results of K-means clustering with k = 2 clusters. Each dot represents a synthetic replicate generated by subsampling each repertoire to a common depth. This subsampling was repeated 10 times per repertoire
