Nature 2021; 592: 80–85https://www.nature.com/articles/s41586-021-03345-1These authors performed whole-genome sequencing (WGS) of 86 bulk placental samples and of 106 microdissections of placental tissue in order to reconstruct the development of human placental cells from data on somatic mutations. They found that the placenta comprises of multiple very large, genetically dis...
