Gene expression patterns underlie development, but their systematic detection in whole embryos has remained elusive. We introduce a whole-embryo imaging platform using multiplexed error-robust fluores...

FoxQ2 is a highly conserved class of Forkhead-box transcription factors expressed on the anterior side of the body in cnidarians and bilaterians. Despite this conserved expression pattern, recent phyl...

A conserved Wnt-regulated molecular signature sets forebrain position and identity in chordates.
