We investigated the development of the lateral line system of the Pacific hagfish, Eptatretus stouti, using three-dimensional reconstructions from serial sections. Adult hagfishes possess a number of densely innervated skin grooves of unknown function, and these grooves do not contain typical lateral line receptors (i.e. neuromasts). However, three separate lateral line placodes appear to be present during development and these placodes give rise to groups of neuromast primordia. Unlike in other craniates, the neuromast primordia do not develop into neuromasts, but they apparently transform into the skin grooves of adults.
我们利用连续切片的三维重建技术，研究了太平洋盲鳗（Eptatretus stouti）侧线系统的发育过程。成年盲鳗拥有许多神经密集分布但功能未知的皮肤沟，这些沟内并不包含典型的侧线感受器（即神经丘）。然而，在发育过程中似乎出现了三个独立的侧线基板，这些基板产生了神经丘原基群。与其他有头类动物不同的是，神经丘原基并不会发育成神经丘，而是显然转变为成年盲鳗的皮肤沟。
