What are myeloblast cells?
myeloblast, immature blood cell, found in bone marrow, that gives rise to white blood cells of the granulocytic series (characterized by granules in the cytoplasm, as neutrophils, eosinophils, and basophils), via an intermediate stage that is called a myelocyte.
What is the difference between a myeloblast and an myelocyte?
As nouns the difference between myelocyte and myeloblast is that myelocyte is a large cell, found in bone marrow, that becomes a granulocyte when mature while myeloblast is (biology) an immature cell of bone marrow that develops into a myelocyte.
What does a myeloblast look like?
Myeloblasts have a diameter of 10–20 µm, are derived from HSCs and are normally found in the bone marrow. Morphologically, they are characterized by a large round to oval nucleus with a small basophilic cytoplasm with no evident granules.
How many myeloblasts are in a normal bone marrow?
Please check your laboratory’s procedures and policy.) While the myeloid sequence tends to be the predominant cell type found in normal bone marrows, myeloblasts should make up less than 5% of the bone marrow’s nucleated cells.
What do you need to know about myeloblasts?
Myeloblast 1 Normal bone marrow cells. SN Wickramasinghe, 2 Acute Myeloid Leukemia. The myeloblasts are large, often with indented nuclei… 3 Myelodysplastic Syndromes.

Is the myeloblast part of the reticulum?
There is also an intermediate phase between the myeloblast and these primitive reticulum cells, namely the hemocytoblast. At this time several developing blood cell lines are available, like erythropoiesis and thrombopoiesis. Granulopoiesis is regulated by humoral agents, like colony-stimulating factor (CSF) and interleukin 3 .
Is the myeloblast a unipotent stem cell?
The myeloblast is a unipotent stem cell, which will differentiate into one of the effectors of the granulocyte series.
