Figure 3. Expression of Ret and Gfrα Genes in LMC Neurons.
(A–G) Expression patterns of Ret, Gfrα1 and Gfrα3 in MNs along the rostrocaudal axis, aligned with expression of Hoxa5, Hoxc8, Meis1/2, Foxp1, Pea3 and Scip at e12.5. (H–N) Expression of Ret, Gfrα1 and Gfrα4 in MNs aligned with Hoxa5, Hoxc8, Meis1/2, Foxp1, Pea3 and Scip in chick at st29. (O) Summary of the expression profiles of mouse (m) and chick (c) Ret, mGfrα1, cGfrα1, mGfrα3 and cGfrα4 along the rostrocaudal axis. Expression domains of Hoxa5, Hoxc8, Meis1/2, Hoxc6, Pea3 and Scip are depicted for positional comparison. (P) Summary of the intrasegmental expression profile of Ret, mGfrα1, cGfrα1, mGfrα3 and cGfrα4 in brachial MNs. See also Figure S3.
