The role of cells of the diffuse neuroendocrine system in development and maintenance of individual organs and tissues remains poorly understood. Here we identify a regulatory region sufficient for accurate in vivo expression of synaptophysin (SYP), a common marker of neuroendocrine differentiation, and report generation of Tg(Syp-EGFPloxP-DTA)147Ayn (SypELDTA) mice suitable for flexible organ-specific ablation of neuroendocrine cells. These mice express EGFP and diphtheria toxin fragment A (DTA) in SYP positive cells before and after Cre-loxP mediated recombination, respectively. As a proof of principle, we have crossed SypELDTA mice with EIIA-Cre and PB-Cre4 mice. EIIA-Cre mice express Cre recombinase in a broad range of tissues, while PB-Cre4 mice specifically express Cre recombinase in the prostate epithelium. Double transgenic EIIA-Cre; SypELDTA embryos exhibited massive cell death in SYP positive cells. At the same time, PB-Cre4; SypELDTA mice showed a substantial decrease in the number of neuroendocrine cells and associated prostate hypotrophy. As no increase in cell death and/or Cre-loxP mediated recombination was observed in non-neuroendocrine epithelium cells, these results suggest that neuroendocrine cells play an important role in prostate development. High cell type specificity of Syp locus-based cassette and versatility of generated mouse model should assure applicability of these resources to studies of neuroendocrine cell functions in various tissues and organs.
