Figure 1.
Expression of dbx1a mRNA and dbx1a:GFP reporter. (A–C) In situ hybridization shows that dbx1a mRNA is expressed in the intermediate spinal cord through 14dpf. (D–F) In 3dpf dbx1a:GFP embryos, GFP protein expression is observed in lateral cells negative for GFP mRNA (arrows), suggesting that perdurance of protein can be used to trace the lineage of reporter-expressing cells. Scalebars = 10µm.
