Isolation and Characterization of Tumor-initiating Cells from Sarcoma Patient-derived Xenografts
Published on: June 13, 2019
Abstract:
Consideration is given to the concept of a histologically identifiable monophasic type of synovial sarcoma. It is accepted that a sarcomatous tumour may be encountered where the spindle cells assume a somewhat epithelioid appearance associated with a reticulin pattern unlike that of most other spindle cell sarcomas. The appearance should alert a hsitopathologist to the possibility of a synovial sarcoma and prompt the examination of multiple additional sections in an attempt to find the pathognomonic biphasic pattern. It is not, however, believed that an entire tumour composed of cells of a single type could be identified with certainty as a synovial sarcoma by light microscopy. The term monophasic synovial sarcoma is worthy of retention, but only as a guide towards the establishment of a definite diagnosis by further sampling of the specimen. Other features suggestive of this diagnosis are discussed.

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

The muscle sarcolemma is a plasma membrane enclosing each muscle cell that conducts electrical signals called action potentials. The sarcolemma extends into the cell to form T-tubules, ensuring the neural impulses are uniformly distributed across the entire muscle...
