We investigated the issue of mast cell heterogeneity by cloning mast cell colonies from peritoneal cells in methylcellulose, injecting the cloned cells into the skin and stomach of mast cell-deficient (WB X C57BL/6)F1-W/Wv (WBB6F1-W/Wv) mice, and staining the mast cells that developed in these sites with Berberine sulfate, a fluorescent dye that identifies heparin-containing mast cells. When peritoneal cells of nontreated WBB6F1-+/+ mice were plated in methylcellulose containing pokeweed mitogen-stimulated spleen cell conditioned medium, pure mast cell colonies developed. In contrast, the peritoneal cavity of genetically mast cell-deficient WBB6F1-W/Wv mice lacked the progenitor cells that made mast-cell colonies. The clonal nature of the mast cell colonies was determined by using the giant granules of C57BL/6-bgJ/bgJ mice as a marker: even when mixture of peritoneal cells of C57BL/6-bgJ/bgJ mice and C57BL/6-+/+ mice were plated, all of the resulting colonies consisted of either bgJ/bgJ-type mast cells alone or +/+-type mast cells alone. Individual mast c 11 colonies of WBB6F1-+/+ mouse origin were divided into two parts; one part was directly injected into the wall of the glandular stomach of a WBB6F1-W/Wv mouse, and another part was injected into the skin of the same W/Wv mouse. Injections of 14 of 46 such colonies resulted in development of mast cells in both the "connective tissues" (skin or stomach muscle or both) and the stomach mucosa. Mast cells in the connective tissues were stained with Berberine-sulfate, indicating that they contained heparin, whereas mast cells in the stomach mucosa were not. These results suggest that a single precursor cell can give rise to both "connective tissue-type" and "mucosal" mast cells.

Formation of mast cell colonies in methylcellulose by mouse peritoneal cells and differentiation of these cloned cells in both the skin and the gastric mucosa of W/Wv mice: evidence that a common precursor can give rise to both "connective tissue-type" and "mucosal" mast cells.
