Fine structural study of interdigital membranes during formation of the digits of the duck foot reveals that the interdigital necrosis is accompanied by a high deposition of collagenous material in the epithelio-mesenchymal interface, rupture of the basal lamina and detachment of ectodermal cells into the amniotic sac. These changes are similar to those observed in the regressing interdigital membrane of the chick although their intensity and temporal extension are less pronounced in the duck. It is suggested that these changes account for the disappearance of the marginal zone of the duck interdigital membranes. The possible causal relationship between the different structural changes are discussed.
鸭足趾形成过程中趾间膜的超微结构研究表明，趾间坏死伴随着上皮 - 间充质界面处大量胶原物质的沉积、基膜破裂以及外胚层细胞脱离进入羊膜囊。这些变化与在鸡的退化趾间膜中观察到的变化相似，尽管在鸭中它们的强度和时间延伸不太明显。有人认为这些变化解释了鸭趾间膜边缘区的消失。文中讨论了不同结构变化之间可能的因果关系。
