(a-d) HCR detection of Th (teal) and Dbh (red) in lamprey at T27. Colocalization of the transcripts is seen in cells surrounding the heart and spanning the initial segment of the trunk in bilateral streams. Scale bars = 100 μm. Red asterisk denotes the heart. n = 6 embryos across three independent replicates.
