 Chronic Myeloid Leukaemia
Stem cells are immature blood cells which can divide many times and eventually produce all the lymphocytes and myeloid cells present in the blood.
Throughout most stages of the disease the leukaemic cells found in the bone marrow and the circulating blood appear to be myeloid cells.
Chronic myeloid leukaemia is a form of leukaemia that progresses slowly during the chronic phase of the disease.

 Acute Myeloid (Myelogenous) Leukemia (AML)   (Site not responding. Last check: )
AML is a type of blood cancer in which white blood cells known as "myeloid cells" become cancerous.
In cases of acute myeloid or myelogenous leukemia, the bone marrow produces abnormal blood cells called "myeloblasts." This form of leukemia interferes with the normal function of the bone marrow by replacing normal blood cells with leukemia cells.
When the abnormal "blast" cells grow out of control, the production of normal blood marrow cells is inhibited, causing low numbers of red blood cells, normal white blood cells, and platelets.

This group of French, American, and British doctors decided that acute myeloid leukemias should be divided into 8 subtypes, designated M0 through M7, based on the type of cell from which the leukemia developed.
These defects, rather than the appearance of the cells under the microscope, will be used to classify leukemias and understand their prognoses.
For a patient to be considered in relapse, he or she must have more than 5% blast cells present in the bone marrow.

 Acute myelogenous leukemia - OhioHealth
The cause of acute myelogenous leukemia is damage to the DNA of developing cells in your bone marrow.
The presence of blast cells — immature cells usually found in the bone marrow but not normally circulating in the blood — is another indicator of acute myelogenous leukemia.
It's similar to bone marrow transplant except the stem cells are collected from circulating blood (peripheral blood), rather than from the bone marrow, thanks to a medication that causes larger numbers of stem cells to be released from the bone marrow.

 Developmental biology of zebrafish myeloid cells   (Site not responding. Last check: )
Molecular markers have been characterised for various myeloid cell types and their precursor cells, for example: stem cells (scl, hhex, lmo2), myeloid lineage precursors (spi1/pu.1, c/ebp1), heterophil granulocytes (mpx/mpo), macrophages (L-plastin, fms).
By the second day of life, cells expressing granulocyte- and macrophage-specific genes are scattered throughout the embryo, but tend to aggregate in the ventral venous plexus, which may be a site of their production or a preferred site for their residence.
Equipped with an understanding of the developmental biology of these various myeloid cells and a set of tools for their identification and functional study, we will now be able to exploit the experimental strengths of this model organism to better understand the genetic regulation of myelopoiesis.
