Extended Data Fig. 6: Lamprey sympathoblasts are neural crest-derived.
From: Neural crest origin of sympathetic neurons at the dawn of vertebrates
Lineage tracing of TH+ sympathoblasts. CM-DiI-labeled neural crest (red) localizes to TH+ cells (teal) at (a-c) T27 and (d, e) T30, indicating a neural crest origin. Arrowheads (b, c, and e) indicate CM-DiI-labeled cells. DAPI is shown in white. Scale bars = 20 μm. DA=dorsal aorta, E=esophagus, I=Intestine. Experimental details are shown in Extended Data Table 1.
