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...

Nature. 2021 Sep;597(7876):381–386. doi: 10.1038/s41586-021-03822-7.Brief Summary: This study investigated the mutational background of somatic cells and rates of mutation in 29 distinct anatomical structures and compared these with the male germline from the same donor. The rate of mutation was lowest in spermatogonia.Characterization of mutations that occur in...
