TNFSF14⁺ Natural Killer Cells Prevent Spontaneous Abortion by Restricting Leucine-Mediated Decidual Stromal Cell Senescence

Investigators performed single-cell RNA transcriptomics on endometrial stromal cells and decidual stromal cells and found that cell senescence during decidualization was accompanied by increased levels of the branched-chain amino acid transporter SLC3A2.
