They are now increasingly recognized also for protective roles, for example against infections and venoms. Other functions originally assigned to mast cells in development and physiology, however, have been refuted, and for yet others, the true contribution of mast cells remains uncertain. Mast cells have been implicated in promoting ductal branching in the pubertal mammary gland, the organ that produces and secretes milk in mammals, but these findings are based on mouse models that are not mast cell\u2010specific. In this study, we therefore re\u2010addressed the impact of mast cells on mammary gland branching using several complementary genetic models, including a newly generated transgenic mouse line (\n                    <jats:italic>Ms4a2<\/jats:italic>\n                    <jats:sup>lsl\u2010hDTR<\/jats:sup>\n                    ). We report that neither constitutive deficiency of mast cells, nor their conditional ablation induced at puberty affects mammary gland branching. Our results thus dispute that mast cells promote this process in mice, at least in a unique and non\u2010redundant manner. This study adds to a growing body of work clarifying the biological roles of mast cells and further expands the toolbox available to the field of mast cell research.\n
