The development of transport ability by follicle-associated epithelium was studied in embryonic chick bursae. Developing lymphoid follicles were divided into three morphological types to determine the relationship of epithelial function to lymphoid development. Transport ability was first observed on day 13, two days earlier than obvious morphological evidence of follicle-associated epithelial development. Functional differentiation of the epithelium was, however, closely associated with lymphoid development rather than a day-specific developmental event. It is probable that the lymphoid cells have an inductive influence on the development of the overlying epithelium. Evidence of early embryonic transport by relatively undifferentiated epithelium also suggests that lymphoid development in the bursa may be influenced by epithelial transport.
在鸡胚法氏囊中研究了滤泡相关上皮运输能力的发育。将发育中的淋巴滤泡分为三种形态类型，以确定上皮功能与淋巴发育之间的关系。运输能力在第13天首次观察到，比滤泡相关上皮发育的明显形态学证据早两天。然而，上皮的功能分化与淋巴发育密切相关，而不是特定日期的发育事件。淋巴细胞可能对上覆上皮的发育有诱导作用。相对未分化的上皮在胚胎早期进行运输的证据也表明，法氏囊中淋巴发育可能受上皮运输的影响。
