  • Title: Scanning and transmission electron microscopy of rabbit heart lymphatic capillaries.
    Author: Marchetti C, Poggi P, Piacentini C, Calligaro A.
    Journal: Lymphology; 1991 Mar; 24(1):26-31. PubMed ID: 2051782.
    Abstract:
    The ultrastructural characteristics of the lymphatic capillaries of the rabbit heart were examined by scanning and transmission electron microscopy (SEM and TEM) using similar technical preparation. SEM defined the interrelationships between endothelial cells including the pocket-like structures formed by overlapping between cells and the corresponding intercellular bridges. Except for rare spindle cells apposed on the luminal surface of the endothelium seen only on SEM, these features were confirmed by TEM. On the abluminal side of the lymphatic capillary wall, a rich network of filaments and fibrils was detectable using both ultrastructural techniques. These two modalities (SEM and TEM) complement one another in defining the microanatomy of the lymphatic capillary.
