| abstractText | Mast cells have been implicated in a wide variety of biological responses, but identifying the nature and importance of the mast cell's specific contributions to these reactions has been difficult. W/Wv mice have mutations affecting the c-kit tyrosine kinase receptor which is encoded at the W locus and which is necessary for normal mast cell development. In W/Wv mice, the cells which ordinarily give rise to normal mast cell populations do not adequately respond to a major migration, survival, proliferation and maturation factor expressed in the microenvironments where mast cells ordinarily develop: the c-kit receptor ligand, SCF. As a result, W/Wv mice virtually lack tissue mast cells. However, adoptive transfer to W/Wv mice of immature mast cells derived in vitro from the bone marrow cells of the congenic normal (+/+) mice selectively repairs the mast cell deficiency of the W/Wv recipients. These mast cell knock-in mice can be used to analyze the expression of biological responses in tissues which differ only because they do or do not contain populations of mast cells. This approach permits identification and quantification of the specific contributions of the mast cell to biological responses expressed in the skin, gastrointestinal tract and other anatomical sites, and also greatly facilitates analysis of the mechanisms by which mast cells influence these responses. |
