VH gene family usage in PTECs differs from that in B cells. (a) The VH gene family usage of PTECs differs significantly from that of B cells, especially higher percentage of VH1 in PTECs (****, p < 0.0001). The DH (b) and JH (c) gene family usage of PTECs are similar to those of B cells, except for lower percentage of JH3 in PTECs (*, p < 0.05). Chi-square test was used to compare the frequency of VH, D, JH usage between PTECs and B cells. (d) Distribution of the expressed VH genes of PTECs and B cells on the IgG heavy chain locus. Here, PTECs show a restricted distribution at the 3′ end compared to that of B cells, which express more widely distributed VH genes.
