Extended Data Figure 5. Full segregation of placental and umbilical cord lineages.
Heatmaps of VAFs of early embryonic mutations with the umbilical cord being derived from one clonal lineage. In all cases, one or more placental lineages do not share any genetic ancestry with umbilical cord and are largely unexplained, as indicated by an asterisk (see Methods). P, placenta; UC, umbilical cord; M, maternal.
