用光镜和电镜对正常人皮肤的弹性系统进行了研究。光镜下观察到三种不同类型的纤维：木聚糖纤维、弹力纤维和弹力纤维。最浅层的纤维（木胞纤维）非常薄，垂直于真皮表皮连接处。它们从一个神经丛开始，这个神经丛与网状真皮层中较厚的弹性纤维相连。在电子显微镜下，氧化木聚糖纤维是由直径10-12纳米的管状微纤维束形成的。在真皮的最深处，这些束的核心可见无定形物质。在弹性纤维中，非晶态物质是稀疏的，而在弹性纤维中，非晶态物质是丰富而致密的。
The elastic system of normal human skin was studied by light and electron microscopy. By light microscopy 3 different types of fibers were observed: oxytalan, elaunin and elastic. The most superficial ones (oxytalan fibers) are very thin and directed perpendicularly to the dermoepidermal junction. They start from a plexus with the tinctorial characteristics of elaunin fibers which is connected with the thicker elastic fibers of the reticular dermis. At the electron microscopic level the oxytalan fibers are formed by bundles of tubular microfibrils 10-12 nm in diameter. In the deepest layers of the dermis an amorphous material is seen in the core of these bundles. In the elaunin fibers the amorphous material is sparse, while in the elastic fibers it is abundant and compact.
