Mast cell histamine-releasing activity from stimulated rat neutrophils. 1988

Department of Biology, Tufts University, Medford, Mass.

Mast cell histamine-releasing activity (HRA) has been observed in medium derived from stimulated rat neutrophils pretreated with cytochalasin B. This HRA did not require cell-cell contact between mast cells and neutrophils, and its concentration was increased by increasing the number of neutrophils or by raising the concentration of chemotactic peptide used to stimulate the neutrophils. The HRA survived boiling for 5 min and storage overnight at -20 degrees C. In the absence of neutrophil stimulation, no HRA was observed.

D007958	Leukocyte Count	The number of WHITE BLOOD CELLS per unit volume in venous BLOOD. A differential leukocyte count measures the relative numbers of the different types of white cells.

D008407	Mast Cells	Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.	Basophils, Tissue,Basophil, Tissue,Cell, Mast,Cells, Mast,Mast Cell,Tissue Basophil,Tissue Basophils

D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
