在大鼠和叙利亚金黄仓鼠的呼吸道各级，单独和成组地发现了费尔特细胞。在细支气管分叉和细支气管肺泡连接处有特别大和突出的费尔特细胞群。在整个呼吸道中也发现了单个Feyrter细胞，但它们的分布似乎完全随机。在所有检查的病例中，Feyrter细胞群被中间和浆液性分泌上皮细胞覆盖。偶尔小面积的Feyrter细胞暴露于气道腔。相邻的Feyrter细胞之间存在小的小管样细胞间隙。单个无髓鞘轴突，其中包含神经管，线粒体和囊泡，偶尔被视为密切相关的费尔特细胞。
Feyrter cells were found both singly and in groups at all levels of the respiratory tract studied in both rats and Syrian golden hamsters. Particularly large and prominent groups of Feyrter cells were present at bronchiolar bifurcations and bronchiolar-alveolar junctions. Single Feyrter cells were also found throughout the respiratory tract, but their distribution appeared entirely random. In all cases examined the groups of Feyrter cells were overlaid by intermediate and serous secretory epithelial cells. Occasionally small areas of the Feyrter cells were exposed to the airway lumen. Small canaliculi-like intercellular spaces were present between adjacent Feyrter cells. Single unmyelinated axons which contained neurotubules, mitochondria, and vesicles were occasionally seen in close association with Feyrter cells.
