Extended Data Fig. 9. Transferred labels and matching uncertainty for a mapped IPF dataset.

a, UMAPs of cells originally labeled as stroma, from a mapped IPF dataset⁵⁶ including both healthy and IPF samples. Cells are labeled by annotation transferred from the HLCA core (left), by disease status (middle), and by label transfer uncertainty (right). Cells with labels transferred to fewer than 10 cells were excluded. b, same as a, but showing cells originally labeled as macrophages. c, As b, but now colored by expression of SPP1 and FABP4. SM: smooth muscle. Mph: macrophages. DC: dendritic cells.
