The changes appearing during the development of the human palatine tonsil, both in the surface and in the tonsillar crypt epithelium, were studied from samples of the 16th to 40th prenatal weeks. From the 18th week, we observed areas of mesh-like epithelium in an originally homogeneous stratified squamous epithelium, i.e. the reticularisation began in the tonsillar crypt epithelium. The important role of the epithelial basal membrane in this process is discussed. The diffuse spongy-form type of reticularisation as well as the formation of the intraepithelial passages between the epithelial columns are described. The lymphoid cells and macrophages migrated through these microcrypts and they were frequently seen near the crypt epithelial micropores on the surface of the reticularised epithelium.
我们从妊娠第16至40周的样本中，研究了人类腭扁桃体发育过程中表面及扁桃体隐窝上皮出现的变化。从第18周起，我们在原本均质的复层鳞状上皮中观察到网状上皮区域，即扁桃体隐窝上皮开始出现网状化。本文讨论了上皮基底膜在这一过程中的重要作用。描述了弥漫性海绵状网状化以及上皮柱之间上皮内通道的形成。淋巴细胞和巨噬细胞通过这些微隐窝迁移，并且经常在网状化上皮表面的隐窝上皮微孔附近被观察到。
