Cryostat sections from rat: control (A,C) and
hypertrophic (B,D) ileum autoradiographically labelled for VIP mRNA
(A,B) and galanin mRNA (C,D). VIP mRNA containing nerve cell bodies are
larger, more numerous, and more intensely labelled in hypertrophic
ileum. The number of galanin mRNA containing nerve cell bodies is
particularly increased in the myenteric ganglia where they are larger
and more intensely labelled. Original magnification ×130.
