In acute lymphoblastic leukemia (ALL) patients, the bone marrow niche is widely known to be an important element of treatment response and relapse. Furthermore, a characteristic liver pathology observed in ALL patients implies that the hepatic microenvironment provides an extramedullary niche for leukemic cells. However, it remains unclear whether the liver actually provides a specific niche. T...
Bone marrow (BM)-resident hematopoietic stem and progenitor cells (HSPCs) are known to enter the blood and to home back to the BM. However, whether these migratory HSPCs also follow extramedullary traffic routes is unknown. Our group has recently shown that mouse thoracic duct (TD) lymph contains clonogenic HSPCs that possess short- and long-term multilineage reconstitution capacity in primary ...
BACKGROUND Ependymoma is a glial tumor that occurs in the central nervous system. The intradural extramedullary location of this neoplasm is very rare. The authors report a case of spinal intradural extramedullary ependymoma in a male and discuss its pathogenesis as well as its clinical, radiological, and therapeutical features. CASE DESCRIPTION A 31-year-old man was admitted at the author's ...
Extramedullary disease (EMD) in multiple myeloma (MM) patients is an uncommon event and more attention was directed toward the feature of these patients. Cytogenetic aberration is an important characteristic of MM and is associated with patients' outcome. In this study, we aimed to compare the cytogenetic abnormality of patients with and without extramedullary manifestation, and to analyze the ...
PURPOSE In the current report, we describe a case of an extramedullary ependymoma involving a lumbar nerve root near conus medullaris. Spinal ependymomas commonly present as intramedullary tumors in the cervical or thoracic cord or as tumors arising from the conus medullaris or the filum terminale. In this case, we showed an extramedullary conus ependymoma involving a lumbar nerve root with fil...
Extramedullary myelopoiesis occurs in peripheral organs such as spleen and produces many types of myeloid cells with diverse functions in response to inflammation and infection. It is increased during immune responses and chronic inflammation and is a significant factor in regulating inflammatory diseases and immunity. Increased myeloid cells are found in FoxP3-deficient mice but the mechanism ...
