The distances between fibroblasts and adrenergic varicosities were measured in four distinct blood vessels of the dog, concomitantly with the measurement of corresponding distances between smooth muscle cells and adrenergic varicosities. The results showed a closer anatomical relationship between fibroblasts and adrenergic varicosities as compared to that of adrenergic varicosities and smooth muscle cells. These morphological results indicate that sympathetic neurotransmitter(s) may attain at the fibroblast membrane concentrations similar to those occurring at the smooth muscle cell membrane.
在犬的四条不同血管中测量了成纤维细胞与肾上腺素能曲张体之间的距离，同时测量了平滑肌细胞与肾上腺素能曲张体之间的相应距离。结果显示，与肾上腺素能曲张体和平滑肌细胞之间的关系相比，成纤维细胞与肾上腺素能曲张体之间的解剖学关系更为密切。这些形态学结果表明，交感神经递质在成纤维细胞膜上的浓度可能与在平滑肌细胞膜上的浓度相似。
