Rare cells are often biologically and clinically important, but their low abundance makes them challenging to study using single-cell transcriptomics. Here, the authors develop PURE-seq which integrates FACS and PIP-seq to directly sequence ultra-rare cells. It captures cells at 1 in 1,000,000 rarity, which the authors demonstrate by profiling circulating tumor cells and identifying Egr1 as a regulator of mouse hematopoietic stem cell aging.
