The colony stimulating factor 1 (CSF1), also known as macrophage colony-stimulating factor (M-CSF), is a secreted cytokine which causes hematopoietic stem cells to differentiate into macrophages or other related cell types. Eukaryotic cells also produce M-CSF in order to combat intercellular viral infection.
Under normal conditions, there are usually less than 5 white blood cells per μL of CSF. In a pleocytic setting, the number of lymphocytes can jump to more than 1,000 cells per μL. Increases in lymphocyte count are often accompanied by an increase in cerebrospinal protein concentrations in addition to pleocytosis of other types of white blood ...
type 3, oligoclonal bands in CSF and serum with additional bands in CSF; type 4, identical oligoclonal bands in CSF and serum, type 5, monoclonal bands in CSF and serum, type 6, presence of a single band limited to the CSF. Type 2 and 3 indicate intrathecal synthesis, and the rest are considered as negative results (No MS).
Time-resolved 2D phase-contrast MRI with velocity encoding is the most common method for CSF analysis. [1] CSF Fluid Flow MRI detects back and forth flow of Cerebrospinal fluid that corresponds to vascular pulsations from mostly the cardiac cycle of the choroid plexus. Bulk transport of CSF, characterized by CSF circulation through the Central ...
The cell concentration needs to be known for many experiments in molecular biology, in order to adjust accordingly the amount of reagents and chemicals that are to be applied in the experiment. Studies that examine the growth rate of microorganisms (in other words, how fast they divide to create new cells) require cell counting.
Colony stimulating factor 1 (CSF-1) and interleukin-34 (IL-34) are both CSF1R ligands. Both ligands regulate myeloid cell survival, proliferation, and differentiation, but CSF-1 and IL-34 differ in their structure, distribution in the body, and the specific cellular signaling cascades triggered upon binding to CSF1R.

GM-CSF is a monomeric glycoprotein that functions as a cytokine—it is a white blood cell growth factor. [6] GM-CSF stimulates stem cells to produce granulocytes (neutrophils, eosinophils, and basophils) and monocytes. Monocytes exit the circulation and migrate into tissue, whereupon they mature into macrophages and dendritic cells.
Fluid-attenuated inversion recovery (FLAIR) is a magnetic resonance imaging sequence with an inversion recovery set to null fluids. For example, it can be used in brain imaging to suppress cerebrospinal fluid (CSF) effects on the image, so as to bring out the periventricular hyperintense lesions, such as multiple sclerosis (MS) plaques.
