Fig. 2. Exocrine gene expression in isolated whole guts. (A–C) Amylase expression. Expression of amylase is first detected in the ventral pancreas at stage 41. By stage 45, however, expression has spread throughout both the dorsal and ventral pancreas. (D–F) Elastase expression. As seen with amylase, elastase is first detected in the ventral pancreas and thereafter throughout the whole pancreas. (G–I) Trypsinogen expression. The time course of trypsinogen expression is identical to amylase. (A,D,G) Stages 40–41. (B,E,H) Stages 42–44. (C,F,I) Stages 45–46. |
