TI  - Electron microscopic study of novel threadlike structures on the surfaces of 
      mammalian organs.

AB  - The ultrastructures of novel threadlike structures (NTSs) and corpuscles on the 
      surfaces of internal organs of rats were investigated using electron microscopy. 
      The samples were studied in situ by using a stereomicroscope and were taken for 
      further morphological analysis. Scanning electron microscope (SEM) images 
      revealed a bundle structure of threadlike tissue, which was composed of several 
      10-micro m-thick subducts. The surfaces of the corpuscles were rather coarse and 
      fenestrated. The corpuscles had cucumber-like shapes with an average length of 
      about 2 mm and a thickness of about 400 micro m. Transmission electron microscope 
      (TEM) images disclosed disordered collagen fibers, which formed the extracellular 
      matrix of the threadlike tissue, and immune-function cells, like macrophages, 
      mast cells, and eosinophils. Sinuses of various diameters, which were thought to 
      be cross-sections of the lumens of the subducts, were observed in the TEM, 
      cryo-SEM and focused-ion-beam SEM images. These SEM images were obtained for the 
      first time to reveal the detailed structure of the NTSs that were only recently 
      discovered.
