The structure and anatomical relationships of cartilage canals in the developing vertebral endplates of rabbits and humans are described in this study. In newborn rabbits, we observed a similar morphology and topologic arrangement to that in human fetal spines. Each vascular organ consisted of an arteriole, a glomerular tuft of sinusoidal capillaries, recurrent venules, and supporting loose connective tissue. Because the canals terminate adjacent to the intervertebral discs, they may provide an important source of nutrition to the disc during development when it is sandwiched between two layers of thick hyaline cartilage and contains no intrinsic vascular supply.
本研究描述了兔和人发育中椎体终板软骨管的结构及解剖关系。在新生兔中，我们观察到其形态和拓扑排列与人类胎儿脊柱相似。每个血管器官由一条小动脉、一簇肾小球样的窦状毛细血管、回流小静脉和支持性疏松结缔组织组成。由于这些管道在椎间盘附近终止，它们可能在发育过程中为夹在两层厚透明软骨之间且无内在血管供应的椎间盘提供重要的营养来源。
