本研究的主要目的是探讨脊索鞘的起源和表观遗传学关系。此外，还收集了一些关于切除脊索或用其他拉长的材料(如人的头发)代替脊索对胚胎发育的影响的数据。Kitchin(1949)和Mookerjee(1952)最近描述了后一种研究中遇到的许多现象，因此我们将主要关注与脊索鞘有关的问题。
到目前为止，人们普遍认为鞘是脊索的分泌产物。这一观点是基于一些比较解剖学家的描述性研究，他们研究了鞘的形成和脊柱的起源。
The prime object of the studies to be described here was the investigation of the origin and epigenetic relations of the notochordal sheath. In addition, some data were collected concerning the effects on the development of the embryo of the removal of the notochord or its substitution by some other elongated strand of material, such as human hair. Many of the phenomena encountered in the latter studies have recently been described by Kitchin (1949) and Mookerjee (1952), so that it is with questions relating to the notochord sheath that we shall be chiefly concerned.
It has been generally accepted up to the present time that the sheath is a secretory product of the notochord. This view is based on the descriptive studies of a number of comparative anatomists who dealt with the formation of the sheath and the origin of the vertebral column.
