TLDR
A case of histologically typical synovial sarcoma has been studied by means of electron microscopy and confirmed the confirmation at the ultrastructural level of the biphasic pattern of the tumor.Abstract:
A case of histologically typical synovial sarcoma has been studied by means of electron microscopy. The more important findings are: 1. the confirmation at the ultrastructural level of the biphasic pattern of the tumor; 2. the presence of a basal lamina between the “epithelial” and the “stromal” part of the tumor; 3. the presence of specialized junctions in the form of desmosomes or maculae adhaerentes between neoplastic cells; these are mostly seen in the epithelial part of the tumor but are not infrequent among stromal cells, and 4. the existence in the extracellular component of the neoplasm of mostly amorphous material, microfibrils, and thin fibrils without periodicity. Only a few mature collagen fibers are seen.read more

Electron microscopy of the human synovial membrane.
TL;DR: The structure of the lining cells at the surface of the synovial membrane facing the joint cavity has been studied by electron microscopy and the probable functions of these cells are discussed in the light of current knowledge of the metabolism and function of the Synovial membranes.

TL;DR: The stability, consistent presence, and intimate association of the mucopolysaccharide coat suggest that it may be an integral part of the plasmalemma rather than an "extraneous coat."

TL;DR: The interaction between growth forces and the maintenance of structural integrity by cell adhesions may explain the development of specific structural entities within the tendon.
