Sharing of clonotypes across developmental stages. a. Venn diagram showing the distribution of the 120 shared clonotypes between FL, FBM and post-natal PB cells. b, c & d. Sharing of clonotypes between FL and FBM, FL and post-natal, and FBM and post-natal B-cells, respectively. None of the clonotypes was shared by > 2 developmental stages. Details of the clonotypes shown in b, c & d are shown in Tables S6, S7 & S8 respectively. e. Abundance of clonotypes shared between FL and FBM, FL and post-natal, and FBM and postnatal B-cells. f. Abundance of FL-PB shared clonotypes. Two left columns show shared clonotypes whose abundance is higher in FL rather than in PB, the two right-most columns show shared clonotypes with abundance higher in PB rather than in FL. g. Abundance (%) and sharing of stereotypic IgH receptors associated with CLL in fetal and postnatal B-cells showing 11 subsets shared between FL and FBM, 13 subsets shared between child and adult PB B-cells and 3 subsets shared across all 4 stages (see Table S9; *p < 0.05, ****p < 0.0001).
