Another essential test is fluorescence in situ hybridization (FISH), which is used to detect common chromosomal abnormalities. As MM is characterized by patchy and focal infiltration of the bone marrow, the aforementioned modalities have common limitations that stem from their reliance on sampling of ...
other than rodents are used, it is recommended that the measurement of bone marrow chromosomal aberration be integrated into another appropriate toxicity test. 6. If there is evidence that the test substance(s), or its metabolite(s), will not reach the target tissue, it may not be appropr...
Little is known about how leukemia cells alter the bone marrow (BM) niche to facilitate their own growth and evade chemotherapy. Here, we provide evidence that acute myeloid leukemia (AML) blasts remodel the BM niche into a leukemia growth-permissive and
The distribution of historical control results from male mice tested in the bone-marrow micronucleus test was used to optimize counting procedures and to develop decision rules for evaluating test results. The ratio of normochromatic to polychromatic erythrocytes followed a normal distribution, while the...
Blood or bone marrow specimens collected for this test must reach the laboratory in an expeditious manner (in our laboratory, we reject specimens that are >48 h old) and should begin RNA extraction and processing immediately. Moreover, the BCR-ABL1 quantity detected is typically given in ...
一、The bone marrow niche for haematopoietic stem cells 1、(P4) These studies suggested that endothelial cells are one component of the HSC niche, but did not address whether they directly or indirectly regulate HSC maintenance in vivo.
Here, we investigated the effect of low oxygen tension on the regenerative potential of bone-marrow MSCs. It turned out that incubation of MSCs under a 5% oxygen atmosphere resulted in increased proliferative activity and enhanced expression of multiple cytokines and growth factors. Conditioned growth...
Bone marrow adipose tissue (MAT) is negatively associated with bone mass. Since osteoblasts and adipocytes are derived from the same precursor cells, adipocyte differentiation may occur at the expense of osteoblast differentiation. We used MAT-deficient
