Hematopoietic stem/progenitor cells (HSPCs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. Interacting factors such as stromal derived factor-1/CXCR4, very late antigen-4/vascular cell adhesion molecule-1, Lymphocyte function-associated antigen-1/ intercellular adhesion molec...

PURPOSE We explored appropriate scan timing for bone marrow imaging enhanced using superparamagnetic iron oxide (SPIO) and evaluated the usefulness of SPIO in differentiating metastasis and osteomyelitis in patients. METHODS To determine the adequate scan timing after administration of SPIO, 5 healthy subjects were examined using a 1.5T magnetic resonance (MR) imaging scanner. Sagittal images...

Subcutaneous transplants of bone marrow mesenchymal stem cells (BMMSCs) are capable of generating ectopic bone and organizing functional hematopoietic marrow elements in animal models. Here we report that immunocompromised mice received subcutaneous BMMSC transplants using hydroxyapatite tricalcium phosphate as a carrier suppressed age-related degeneration in multiple organs and benefited an in...

Chemotherapy often causes damage to hematopoietic tissues, leading to acute bone marrow suppression and the long term development of leukemias. Niacin deficiency, which is common in cancer patients, causes dramatic genomic instability in bone marrow cells in an in vivo rat model. From a mechanistic perspective, niacin deficiency delays excision repair and causes double strand break accumulation...

The myelodysplastic syndromes (MDSs) are a group of clonal stem cell disorders resulting from aberrations within hematopoietic stem cells (HSCs), which may lead to the onset of a number of diseases, including acute myeloid leukemia (AML). Recent studies have demonstrated that the expression levels of the DLK1 gene are increased in MDS. In order to determine whether the addition of DLK1 affects ...

Anaemia is common among human immunodeficiency virus (HIV)-infected patients. It may be directly attributable to the virus or may be caused by opportunistic infections, neoplasms or drugs that cause either bone marrow suppression or haemolysis. Pure red cell aplasia (PRCA) is an uncommon haematological disorder that causes severe transfusion dependant anaemia. We report a 36 year-old female wit...

Diverging from eliminating tumors, many anticancer agents can result in drug resistance and myelosuppression or bone marrow suppression in patients during the course of chemotherapy. Drug resistance and myelosuppression are two major impediments to the success of chemotherapy. Recent study of Bhinge et al. demonstrates that glucosylceramide synthase (GCS) can determine the opposite effects of d...

Multiple myeloma (MM) is a clonal B-lymphocyte neoplasm of terminally differentiated plasma cells. Imaging modalities which allow the recognition of the effects of myeloma cells on the skeletal system have been utilized for a long time. Herein, we represent a patient with generalized osteoporosis and hypercalcemia, who was referred for parathyroid scan, in whom the widespread bone marrow techne...

oxaliplatin, a third generation of platinum-based anti-neoplastic agent has been approved for colorectal cancer in both adjuvant and metastatic settings. in addition, oxaliplatin is also indicated for other gastrointestinal malignancies such as metastatic pancreatic cancer in combination with gemcitabine. its common toxicities include infusional hypersensitivity reaction (hsr), gi symptoms with...
