Histoenzymatic methods and in situ hybridization were used to follow AChE expression in rabbit embryos from 10 to 15 days. Transcripts of AChE are detected at the same developmental stages in all structures where enzymatic activity is found, except in neuronal extension and the ventral part of mesonephros. AChE and BChE expression were compared. BChE transcripts are detected before BChE activity can be revealed in blood cells and mesonephros.
