Abstract
A technique is described for the enzymatic dispersion of mast cells in high yield from human infant foreskin. Dispersed mast cells exhibit high viability as assessed by light microscopy, low spontaneous histamine release, and survival in culture. Dispersed mast cells release histamine in response to immunological stimulation and synthetic secretagogues including ionophore A23187, compound 48/80 and poly-L-lysine. Reactivity to these stimuli indicates that cutaneous mast cells differ in their properties from human pulmonary mast cells.
