nguyên tử bào
Trong bệnh bạch cầu cấp dòng tủy, số lượng nguyên tử bào trong tủy xương tăng bất thường.
Definition
- Noun (Biology, Histology):
- Myeloblast: The earliest identifiable, immature precursor cell in the bone marrow that will develop into a granulocyte (a type of white blood cell, such as a neutrophil, eosinophil, or basophil). It is a large cell with a large nucleus and prominent nucleoli.
Usage Examples
- Noun:
- Trong bệnh bạch cầu cấp dòng tủy, số lượng nguyên tử bào trong tủy xương tăng bất thường. (In acute myeloid leukemia, the number of myeloblasts in the bone marrow increases abnormally.)
- Nguyên tử bào phát triển thành tiền nguyên tủy bào. (The myeloblast develops into a promyelocyte.)
Advanced Usage
- The term "nguyên tử bào" is a specific, technical term used almost exclusively in medical and biological contexts, particularly in hematology (the study of blood) and oncology.
- It is a component of the granulocyte cell lineage. Abnormal proliferation or maturation arrest at the myeloblast stage is a hallmark of acute myeloid leukemia (AML).
Variants and Related Words
- Bạch cầu hạt (n): Granulocyte. The mature type of white blood cell that a myeloblast eventually becomes.
- Tủy xương (n): Bone marrow. The soft tissue inside bones where myeloblasts and other blood cells are produced.
- Bệnh bạch cầu cấp dòng tủy (n): Acute Myeloid Leukemia (AML). A cancer where myeloblasts multiply uncontrollably.
Synonyms
- Myeloblast (English equivalent, direct synonym).
Notes on Terminology
- The provided reference from the Vietnamese-French dictionary correctly equates "nguyên tử bào" with "myéloblaste" (French for myeloblast).
- It is important not to confuse "nguyên tử bào" (myeloblast, a cell) with "nguyên tử" (atom, in physics). The suffix "bào" indicates it is a biological cell.
