1. In this study mast cells were found to comprise 2.1% of total cells recovered by enzymatic digestion of human lung tissue. 2. This mast cell population consisted of 79% formalin-sensitive, Alcian Blue-positive mast cells and 21% formalin-insensitive, Alcian Blue-positive mast cells. 3. By the use of centrifugal elutriation and subsequent Percoll gradient centrifugation, separate mixed cell populations could be obtained in which the mast cell constituents were either of the formalin-sensitive or -insensitive type. 4. Cell suspensions in which formalin-sensitive cells comprised 97% of mast cells contained approximately 1.34 pg of histamine per mast cell, whereas in preparations in which mast cells were 84% formalin-resistant the histamine content was approximately 4.17 pg of histamine per mast cell. 5. The histamine release upon anti-immunoglobulin E challenge of formalin-sensitive mast cells was greater than the release by formalin-insensitive mast cells. 6. After challenge with opsonized zymosan, only formalin-sensitive mast cells were able to release histamine. 7. Leukotriene C4 release was observed when formalin-sensitive mast cells were challenged with antiimmunoglobulin E. Formalin-insensitive mast cells showed no release of leukotriene C4. 8. Prostaglandin D2 release was observed when formalin-insensitive mast cells were challenged with antiimmunoglobulin E. Formalin-sensitive mast cells showed no release of prostaglandin D2.

Chediak Higashi Syndrome

Mast cells of beige (C57BL/6J) (bg-j/bg-j) mice were examined histochemically and ultrastructurally. Mast cell granules in the beige mice were markedly enlarged and irregular in shape. Granule contents stained uniformly with acidified toluidine blue, but with ruthenium red and Alcian Blue-safranin, two components were evident. The rims of the abnormal granules stained with ruthenium red and with Alcian Blue; the centers of the granules were clear with ruthenium red and stained with safranin. Mast cell granules thus represent another abnormal organelle in the Chédiak-Higashi syndrome.

Chondroitin Sulfate E

Human bone marrow-derived mast cells (hBMMCs), differentiated in vitro in suspension culture and under the influence of human peripheral blood mononuclear cells conditioned medium (hCM), were tested for their response to recombinant human interleukin-3 (rhIL-3) and for their behavior in different microenvironments. The hBMMCs were incubated in the presence of rhIL-3 and the changes in their proliferation rate were determined. Recombinant hIL-3 induced a more than sixfold increase in 3H-thymidine uptake into the hBMMC DNA in a dose-dependent manner. Human CM used as a control for proliferation response induced a more than eightfold maximal proliferation rate increase. Rabbit anti-rhIL-3 completely inhibited hBMMC 3H-thymidine uptake induced by rhIL-3 and decreased the hCM-induced proliferation by approximately 50%. These hBMMCs were cocultured with four different mytomicin C-treated cell monolayers and assayed for phenotypic changes. After only 2 days in coculture with either embryonic mouse skin-derived fibroblasts (MESFs) or human skin-derived fibroblasts (HSFs), a marked increase in granule number and density was noted on staining with toluidine blue. Mast cells that initially stained alcian blue+/safranin- at day 0 of coculture became alcian blue+/safranin+ during the coculture period. Human BMMC proteoglycan synthesis shifted from approximately 85% chondroitin sulfate E to approximately 60% heparin within 14 to 19 days of coculture with the MESF monolayer and to approximately 50% heparin within 19 days of coculture with the HSF monolayer. None of the above- mentioned changes were noted in cocultures of hBMMCs with 3T3 cell line fibroblast monolayers or in cocultures with bovine vascular endothelium (BVE) cell monolayers. These results demonstrate microenvironmental effects exerted by the MESF and HSF monolayers on IL-3-dependent hBMMCs similar to those reported in the conversion of murine mast cell phenotype.

Agar Culture

Abstract Soft agar culture of mononuclear cell fractions prepared from rat peripheral blood yielded numerous colonies consisting of mast cells. The mast cell nature of the cells was established by ultrastructural and histochemical analyses as well as by the demonstration the the colonies contained histamine and that the cells possessed receptors for the Fc component of IgE. Stringent criteria for the distinction of mast cells from monocytes/macrophages that could have metachromatic inclusions were applied. The alcian-blue-safranin technique delineated the maturation of mast cell granules by showing the loss of alcian-blue and increase in safranin-positive organelles presumed to reflect the increase in N-sulfated polysaccharides representing heparin. The mast cells exhibited low or absent reactions for peroxidase, alpha-naphthyl butyrate, periodic acid Schiff, and Sudan black reacting lipid, whereas macrophages stained in parallel were positive for these substances. Since it is known that extracellular conditions may cause variations in phenotypic expression, the observations have led to the hypothesis that mast cells and macrophages may have a common precursor.
