cell mark·'er

an identifying characteristic of a cell; for example, formation of rosettes with sheep erythrocytes as a marker of T lymphocytes, or the presence of surface immunoglobulin as a marker of B lymphocytes.

In conclusion, they said that the inter-individual variations of endothelial cell marker expression and soluble adhesion molecules might explain why some patients develop adequate collateral circulation whereas others do not, as well as the functional endothelium, inflammatory cells, specifically monocytes, and endothelial progenitor cells.
When the nanobots meet up with a particular protein that can indicate cancer (in their experiment, Douglas and his team used a leukemic cell marker), the nanostructure unlocks itself and releases a cancer-fighting antigen.
It has a new chapter on flow cytometry and its application in identifying abnormalities in cell marker expression.
Researchers in Nova Scotia, Canada, found that a tumour cell marker is a receptor for the virus, suggesting it could be used against lung, breast, colon and ovarian cancer.
A first chapter reviews the basics of flow cytometry, and others consider such topics as stem cell analysis and sorting using side population analysis, analyzing drug transport and efflux in stem cells, identifying and isolating very small embryonic-like stem cells from murine and human specimens, mesenchymal stromal cells and their clinical applications, the flow cytometric characterization of neural progenitors derived from human pluripotent stem cells, limbal stem cells and corneal regeneration, sorting spermatogonial stem cells, and tumor stem cell marker expression in cells from body cavity fluids.
ABCG2 is considered as a side population stem cell marker (15).
The histopathologic review of the skin biopsy confirmed the diagnosis of LC in this case, with negative CD20 cell marker and positive chloroacetate esterase reaction and lysozyme markers (9,11-12).
They then analyzed the uptake of the proliferative cell marker 5-bromo-2-deoxyuridine (BrdU4, also known as brominated deoxyuridine), with the objective of elucidating the mechanism of anti-CXCL10 antibody in hepatic regeneration, and found that the number of BrdU-positive hepatic cells increased markedly in mice administered anti-CXCL10 antibody.
To characterize the immune response in inoculation eschars during ATBF and Mediterranean spotted fever, paraffin sections were stained with the polymorphonuclear leukocyte marker CD 15 (Immunotech, Marseille, France), the macrophage marker CD68 (Dako, Trappes, France), the T-lymphocyte marker CD3 (Dako), the B-lymphocyte marker CD20 (L26, Dako), and the endothelial cell marker Factor VIII-related antigen (Dako) by using the peroxidase-based method described above.
They are positive for the neural stem cell marker CD133 and have a marked capacity for self renewal and differentiation.
To further explore the notion that adult cardiac stem cells exist, they microscopically examined adult rat myocardium and identified cells negative for the expression of blood lineage markers (Lin-) but positive for the stem cell marker c-kit-POS, which is the receptor for stem cell factor.
In the present study, we demonstrated that GSCs with high expression of the stem cell marker, CD44, were present in the periphery of GBM.
