Expression pattern of the col1a2^NTR-mCherry line. A confocal z-stack of col1a2:Gal4; UAS:NTR-mCherry; α-actin:GFP embryos at 3 dpf shows mCherry expression (green) in dermomyotome cells, some muscle fibers, tenocytes and notochord-associated cells (arrows). Muscle fibers are labeled with α-actin:GFP (magenta). Scale bar: 50 μm.
