Paper on stem-cell-derived trophoblast organoids

Our paper on stem-cell-derived trophoblast organoids (SC-TOs) was published in Cell Stem Cell today. In this work we describe a methodology for deriving self-renewing 3D trophoblast organoids from naive human pluripotent stem cells (hPSCs). Using single cell transcriptome analysis, we demonstrate that these organoids contain diverse trophoblast progenitor and specialized cell types that closely correspond to trophoblast identities in the post-implantation embryo. These organoid cultures also model placental X inactivation dynamics and selective vulnerability to emerging pathogens (SARS-CoV-2 and Zika virus). Big congrats to all members of the team, especially Rowan Karvas, and our collaborators Indira Mysorekar, Sabine Dietmann, Jacco Boon, and Liang Ma!
