Several cancer cell lines were imaged homing to specific regions of the bone marrow endothelium, and disruption of the interaction between SDF-1 and CXCR4 blocked homing of cancer cells to these regions (Sipkins et al., 2005).
Myeloid toxicity and neurotoxicity are common, resulting from mitotic arrest-related impairment in cycling bone marrow cells and functional disruption in neuronal cells.
Currently, the most probable hypothesis is that the molecular diffusion of water is substantially increased in osteoporotic fractures because of bone marrow edema and the disruption of the trabecular structure.
They are thought to develop when self-reactive lymphocytes escape from tolerance and are activated or when incomplete thymic and/or bone marrow clonal selection or disruption of the anergy of autoreactive lymphocytes perturb the delicate balance of non-self-antigen and self-antigen recognition [ 1].
The guanine-nucleotide-binding protein stimulatory α subunit (Gαs) is necessary for the homing and engraftment of haematopoietic stem and progenitor cells to bone marrow, as demonstrated by its disruption in adult mice deficient in Gαs.
Our results show that deletion of ezrin in the germline leads to a severe reduction in cellularity of bone marrow, spleen and thymus, and disruption of thymic architecture.
Dose reduction and premedication strategies for the most common ixabepilone-related AEs are summarized in Table 5. Myelosuppression, a common AE associated with cytotoxic chemotherapy, arises from drug-related disruption of bone marrow.
Bone marrow oedema, osteitis pubis, tendon disruption as well as fluid in the symphysis have all been shown to be present on MRI findings in patients with ID [ 14].
Cryopreservation of harvested bone marrow is associated with erythrocyte disruption and requires the addition of dimethyl sulfoxide (DMSO), of which high concentrations may cause in vivo haemolysis during infusion [ 44]; however, haemoglobinuria due to marrow infusion rarely leads to ARF [ 44].
On the other hand, the space between fat and bone in the boundary of each pore ranges from less than 1 μm (when endosteum is damaged or absent due to pathologies) to 10 20 μm [ 50] or more, in the case of trabecular disruption or bone marrow irradiation.
