What is Hematolymphoid?
hematolymphoid (not comparable) Relating to both blood and lymph quotations ▼
What hematologic condition is a malignant tumor of lymphoid tissue?
A lymphoma is a malignant tumor composed of lymphocytes, and (less commonly) histiocytes, that arise from lymph nodes, the spleen, or other sites of lymphoid tissue anywhere in the body.
Which techniques are used in the diagnosis of Hematolymphoid neoplasms?
Polymerase chain reaction (PCR) is currently the most widely used molecular technique in clinical laboratories to evaluate genotypic abnormalities in hematolymphoid neoplasms.
Is Immunophenotyping the same as flow cytometry?
The most common use of flow cytometry is in the identification of markers on cells, particularly the immune system or immunophenotyping. It is the desire to detect an increased number of cell subsets of the immune system that has driven the increase in multicolor flow cytometry.
Where does hematopoiesis occur?
In humans, hematopoiesis begins in the yolk sac and transitions into the liver temporarily before finally establishing definitive hematopoiesis in the bone marrow and thymus. Experiments with human embryos confirm observations in the hemangioblast, a common precursor for endothelial and hematopoietic cells.
In what tissue would leukemia originate?
Leukemia begins in the developing blood cells in the bone marrow. All blood cells start out as hematopoietic (hemo = blood; poiesis = make) stem cells. The stem cells undergo multiple stages of development until they reach their adult form. First, blood stem cells develop into either myeloid cells or lymphoid cells.
What are hematologic malignancies?
Hematologic malignancies are cancers that begin in blood-forming tissue, such as the bone marrow, or in the cells of the immune system. There are three main types of hematologic malignancies: leukemia, lymphoma and multiple myeloma.
What is a hematolymphoid malignancy?
They are primary cancers of blood, bone marrow and lymphoid organs associated with high mortality. There are three main types of hematolymphoid malignancy: Leukemia is a blood cancer that originates in the blood and bone marrow.
What is hemolymph in arthropods?
Hemolymph. In addition to hemocytes, the plasma also contains many chemicals. It is the major tissue type of the open circulatory system characteristic of arthropods (e.g. arachnids, crustaceans and insects ). In addition, some non-arthropods such as molluscs possess a hemolymphatic circulatory system.
What is the structure of haemolymph?
Hemolymph. It is composed of a fluid plasma in which hemolymph cells called hemocytes are suspended. In addition to hemocytes, the plasma also contains many chemicals. It is the major tissue type of the open circulatory system characteristic of arthropods (e.g. arachnids, crustaceans and insects ).
What is the function of the hemolymph in animals?
Hemolymph fills all of the interior (the hemocoel) of the animal’s body and surrounds all cells. It contains hemocyanin, a copper -based protein that turns blue when oxygenated, instead of the iron -based hemoglobin in red blood cells found in vertebrates, giving hemolymph a blue-green color rather than the red color of vertebrate blood.
