Extended Data Fig. 4: Hand2 acts cell autonomously in PAFF mesenchyme.
From: A median fin derived from the lateral plate mesoderm and the origin of paired fins
a–d, Lateral confocal images of PAFF of 3 dpf embryos. Cells were transplanted into WT hosts from ET37 embryos that were injected with H2B-mCherry mRNA (a,b) or co-injected with H2B-mCherry mRNA and 500 µM hand2 MO (c,d). Fluorescent confocal images of mCherry (magenta) and eGFP (green) (a,c) are overlayed on Nomarski image (b,d). Arrowheads indicate transplanted cells from hand2 MO injected donors (c). Scale Bar: 20 µm (d).
