Erythrocytes, are the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen (O 2) to the body tissues via blood flow through the circulatory system.
see pure red cell aplasia. burst forming unit-erythroid. produced in in vitro cultures of erythroid stem cells. It has low sensitivity to erythropoietin and gives rise to colony forming unit-erythroid which, with erythropoietin, gives rise to erythroid cells. erythroid hypoplasia. see hypoplastic anemia. erythroid leukosis. see avian erythroblastosis. 1  Facebook. 1. cells in the process of changing from one type to another. 2. in the sinoatrial and atrioventricular nodes, small, slow-conducting, heterogeneous cells interposed between the P cells and Purkinje cells. visual cells the neuroepithelial elements of the retina. white cell, white blood cell leukocyte. A cell present in a neoplasm and differentiated from normal tissue cells because of its degree of anaplasia, irregularity of shape, nuclear size, changes in the structure of the nucleus and cytoplasm, increased number of mitoses, and ability to metastasize. Definition. Myeloid sarcoma is a tissue mass that effaces tissue architecture. It is composed of blasts (ie, granulocytic, monocytic, erythroid, or megakaryocytic precursors) and occurs at anatomic sites outside of the bone marrow. Because myeloid sarcoma represents the tissue mass form of various subtypes of acute myeloid leukemia (AML), the diagnosis is equivalent to a diagnosis of AML. Red blood cells (RBCs), also called erythrocytes, are the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen (O 2) to the body tissues —via blood flow through the circulatory system. RBCs take up oxygen in the lungs or gills and release it into tissues while squeezing through the body's capillaries. The cytoplasm of erythrocytes is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells. A microfold cell, which is a cell in the gastrointestinal epithelium covering patches of lymphoid tissue. M cells transport antigens from the intestinal lumen to the underlying lymphoid tissues for recognition and processing. 2. An APUD cell that produces melanotropin and is found in the pituitary gland. A cell present in a neoplasm and differentiated from normal tissue cells because of its degree of anaplasia, irregularity of shape, nuclear size, changes in the structure of the nucleus and cytoplasm, increased number of mitoses, and ability to metastasize. Red blood cells are also known as RBCs, red cells, red blood corpuscles (an archaic term), haematids, erythroid cells or erythrocytes (from Greek erythros for red and kytos for hollow vessel, with-cyte translated as cell in modern usage). RBCs take up oxygen in the lungs or gills and release it into tissues while squeezing through the body's capillaries. The cytoplasm of erythrocytes is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells. fat cell a connective tissue cell specialized for the synthesis and storage of fat; such cells are bloated with globules of triglycerides, the nucleus being displaced to one side and the cytoplasm seen as a thin line around the fat droplet. A cell present in a neoplasm and differentiated from normal tissue cells because of its degree of anaplasia, irregularity of shape, nuclear size, changes in the structure of the nucleus and cytoplasm, increased number of mitoses, and ability to metastasize. In this classification, acute erythroid / myeloid leukemia or acute erythroleukemia was defined as acute myeloid leukemia in which erythroid precursors represented at least 50 % of the nucleated bone marrow cell population with myeloblasts accounting for at least 20 % of the nonerythroid cell population. In addition, our data suggest that the current definition of acute erythroid leukemia, erythroleukemia type remains heterogeneous. One subset of acute erythroid leukemia patients has relatively low blast counts and are diploid. The prognosis of this patient subset is relatively good. Myeloid sarcoma may be composed of the same cell types as AML—that is, granulocytic precursors, monocytic precursors, erythroid precursors, or even megakaryocytic precursors. Various types of myeloid sarcoma are named in accordance with the type of cell that composes the sarcoma (see Disorders, below). Because myeloid sarcoma represents the tissue mass form of various subtypes of acute myeloid leukemia (AML), the diagnosis is equivalent to a diagnosis of AML. Bone Marrow – Hypocellularity, [Erythroid, Granulocytic, Megakaryocytic] Recommendation: To evaluate bone marrow cellularity, that is, the percentage of hematopoietic cells relative to marrow fat, bone marrow from treated animals must be compared with same-site concurrent control bone marrow.
