| Research Abstract |
We obtained the following results with a serious study how to grow the well-differentiated mast cells in vitro culture system. The cultured mast cells are beneficial to develop the mechanism of action of anti-allergic drugs or to judge their effectiveness quickly.
1. Preparation and cultivation of differentiated mast cells: During cultivation in serum-containing medium, well-differentiated peritoneal mast cells gradually lost their histamine-containing granules. However, the disappearance was protected by addition of conditioned medium from, or by co-cultivation with fetal liver cells as a feeder layer cells. Some of grown mast cells have an axon like a single nerve cells. This transformation in shape was accelerated by adding large amount of conditioned medium from fetal cells. IL-3 dependent mast cells (P-3 cells) was also cultivated in the presence of conditioned medium from WHEI cells. Mastocytoma P-815 cells were grown in the presence of butyrate or glucocorticoid. Butyrate stimulated evry differentiation activities (histamine-, serotnin-, heparin-synthesis and granulopoiesis), while glucocorticoid only his-tidine decarboxylase synthesis.
2) Cell activities of cultivated mast cells in the synthesis and the secretion of biological active compounds: DNP-ascaris antiserum and active oligomer of compound 48/80 stimulated the secretion of histamine and various arachidonic metabolites fron cultured mast cells. Also, degranulated mast cells gradually reconstituted their biological amines in granules by cAMP or glucocorticoid.
3) Well-known antiallergic drugs effectively and dose-dependently suppressed the <Ca^(2+)> -dependent secretion mechanism of every types of cultured mast cells. These results show that the cultured mast cells appear to be available in the research and the development of anti-allergic drugs in associaton with the mast cell function.
