Differential expression of trkC mRNA in the chicken embryo from gastrulation to development of secondary brain vesicles.
In situ hybridization revealed that mRNA for the neurotrophin receptor trkC first appears in the chicken embryo at stage 4 anterior to Hensen's node. At stages 6 and 8, trkC mRNA was restricted to the neural plate. By stage 11, trkC mRNA was absent from much of the prosencephalon, the entire mesencephalon and rhombomeres 1 and 4. At stage 15, trkC mRNA expression was limited to rhombomeres 3 and 5, and, by stage 18, there was no apparent expression of trkC mRNA in the hindbrain.
