In the version of this article initially published, in the first sentence of the Results, in the first sentence of the Methods subsection “Visium slide and library preparation for spatial transcriptomics and Cell2Location,” and in the legend of Extended Data Fig. 7, fetal ages were incorrectly described as “weeks post-conception” rather than as gestational age. The errors have been corrected in the HTML and PDF versions of the article.
