VIP and Cart are expressed in a subpopulation of Ret-expressing enteric neurons. Comparisons of gene expression profiles of Ret (A) to VIP (B), and Cart (C) by RNA in situ hybridization suggest that VIP and Cart are expressed in a smaller proportion of the ENS than Ret. A direct comparison of Ret expression (brown in D) and Cart expression reveals that Cart expression is found in only a small proportion of Ret-expressing cells (coexpression of Cart and Ret is seen as black; arrowhead in D).
