Abstract
The subject invention pertains to the development of a novel human mast cell line, USF-MC1. USF-MC1 is a mast cell precursor present in human umbilical cord blood (HUCB) that may be sustained in culture in the absence of exogenous cytokines to serve as a convenient experimental model of human mast cell activation. The SCF-independent human mast cell line USF-MC1 responds to IgE-mediated and IgE-independent stimuli in a way comparable to that of LAD2. USF-MC1 cells are useful for investigation of IgE-mediated activation mechanisms of human mast cells, contributing to the development of effective treatments for allergic disorders and other disorders. The subject invention provides a ready source of human mast cells for research, including pharmacological studies for the screening of various agents, and toxicologic, e.g., for the cosmetic and pharmaceutical industries. The mast cells can also be used as biofactories, for the large-scale production of biomolecules.
