Lymphoblast. A lymphoblast is a modified naive lymphocyte with altered cell morphology. It occurs when the lymphocyte is activated by an antigen and increased in volume by nucleus and cytoplasm growth as well as new mRNA and protein synthesis.
The JY cell line is an Epstein–Barr virus (EBV)-immortalised B cell lymphoblastoid line. JY cells express HLA class-I A2 and class-II DR. JY is a suspension cell line, although the cells are known to grow in clumps. The growth medium is RPMI 1640, 10% fetal calf serum and 1% L-glutamine. [1] JY cells are positive for murine leukemia virus. [2]
Large lymphocytes (12–18 μm in diameter) are probably activated, i.e. immunoblasts, cells with a paler and wider rim of cytoplasm and are often mistaken for monocytes. They have moderate-to-abundant basophilic cytoplasm and a prominent, centrally located, trapezoid-shaped single nucleolus which often has fine strands of chromatin attached to ...
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
Acute lymphoblastic leukemia (ALL) is a cancer of the lymphoid line of blood cells characterized by the development of large numbers of immature lymphocytes. [1] Symptoms may include feeling tired, pale skin color, fever, easy bleeding or bruising, enlarged lymph nodes, or bone pain. [1]
The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count. The normal white cell count is usually between 4 × 10 9 /L and 1.1 × 10 10 /L. In the US, this is usually expressed as 4,000 to 11,000 white blood cells per microliter of blood. [7]
Basic map of B cell lymphopoiesis. Early B cell development: from stem cell to immature B cell Transitional B cell development: from immature B cell to MZ B cell or mature FO B cell. A generally regarded valid map of B cell lymphopoiesis is as follows in sequence, in two parts with the first being in the bone marrow and the second in the spleen ...
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of ...
