Author Correction: Cross-species single-cell transcriptomic analysis reveals pre-gastrulation developmental differences among pigs, monkeys, and humans (Cell Discovery, (2021), 7, 1, (8), 10.1038/s41421-020-00238-x)

In the original publication of this article¹, the description of data source and reference for the identification of epithelial cell lineages of pigs were missing and should be added in Materials and methods section as follows. Lineage identification of cells in Pig The expression matrix of the endometrial epithelium, including the pregnant glandular epithelium (GSM2946041- 44), the pregnant luminal epithelium (GSM2946045-48), the control glandular epithelium (GSM2946030-33), and the control luminal epithelium (GSM2946034-37), was downloaded from GSE109539². The newly added reference² should be cited in the main text as shown below. “To investigate potential roles of the endometrial epithelium may play in pig embryo elongation, we used CellPhoneDB⁴⁵ to predict the ligand–receptor interactions between pregnant womb epithelium (luminal and glandular, P_LE and P_GE)² and PostL-EPIs or PostL-TEs during the elongation stages”. In addition, in the last Venn diagram of Fig. 5c, the labels of 52 and 169 were misplaced and should be interchanged as shown below. (Table presented.).
