Data CitationsPique-Regi R. StatementPlacental and decidual scRNA-seq data from first-trimester examples Tebanicline hydrochloride were downloaded through ArrayExpress (E-MTAB-6701). Data for third-trimester samples previously collected by our group are available through NIH dbGAP (accession quantity phs001886.v2.p1), and newly generated second-trimester scRNA-seq and third-trimester snRNA-seq data are being deposited into the same repository (Supplementary file 1).

E-MTAB-6701 Abstract The pandemic of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) offers affected more Tebanicline hydrochloride than 10 million people, including pregnant women. To day, no consistent evidence for the vertical transmission of SARS-CoV-2 is present. The novel coronavirus canonically utilizes the angiotensin-converting enzyme 2 (ACE2) receptor and the serine protease TMPRSS2 for cell access. Herein, building upon our earlier single-cell study (Pique-Regi et al., 2019), another study, and fresh single-cell/nuclei RNA-sequencing data, we investigated the manifestation of ACE2 and TMPRSS2 throughout pregnancy in the placenta as well as with third-trimester chorioamniotic membranes. We statement that co-transcription of ACE2 and TMPRSS2 is definitely negligible in the placenta, therefore not a likely path of vertical transmission for SARS-CoV-2. By contrast, receptors for Zika virus and cytomegalovirus, which cause congenital infections, Tebanicline hydrochloride are highly expressed by placental cell types. These data show that the placenta minimally expresses the canonical cell-entry mediators for SARS-CoV-2. package in Bioconductor was used to determine presence above background of each probeset corresponding to a given gene (Gautier et al., 2004).
