The postnatal development and maturation of liver, the major metabolic organ, are inadequately understood. We have analyzed 52,834 single cell transcriptomes and identify 31 cell types or states in mouse livers at postnatal day 1, 3, 7, 21 and 56. We observe unexpectedly high levels of hepatocyte heterogeneity in the developing liver and progressive construction of the zonated metabolic functions from pericentral to periportal hepatocytes, which is orchestrated with development of sinusoid endothelial, stellate and Kupffer cells. Trajectory and gene regulatory analyses capture 36 transcription factors, including a circadian regulator Bhlhe40, in programming liver development. Remarkably, we identify a special group of macrophages enriched at day 7 with a hybrid phenotype of macrophages and endothelial cells, which may regulate sinusoidal construction and Treg cell function. This study provides a comprehensive atlas that covers all hepatic cell types instrumental for further dissection of liver development, metabolism and disease. Liang et al. present an atlas of mouse liver development at single cell resolution from newborn to adult. They demonstrate functional maturation of hepatocytes in concert with endothelial, stellate and Kupffer cells and transient emergence of a macrophage group.
