The study presents a comprehensive spatial multiomic atlas of human placenta from the first trimester of pregnancy, based on the analysis of nearly 1 million cells with molecular resolution[2][4]. They used a combination of single-stranded RNA sequencing (snRNA-seq) and chromatin accessibility (snATAC-seq), along with spatial mapping of transcriptomes and epigenomes directly in the tissue[1][2]. The results reveal complex gene regulatory networks and cell-cell interactions that are crucial for proper placental development and successful pregnancy progression[2]. The study identified specific transcriptional programs and cis-regulatory elements that may influence trophoblast differentiation and the risk of placental diseases[2]. Spatial mapping showed how these programs are organized in different parts of the placenta, including the villous nucleus and extravillous trophoblast columns[2]. The authors have also developed a computational model that allows detailed examination of chromatin accessibility and gene expression at the level of individual cells in the placental compartment[1][2]. This atlas serves as a basis for further research on early placental development and complications of pregnancy[2]. The correction to the article concerns administrative details and does not affect the main scientific conclusions[6].
