Spatially and temporally regulated somatic mutations can be achieved by using the Cre/loxP recombination system of bacteriophage P1. To develop a cell type-specific system of gene targeting in the peripheral nervous system, we generated the transgenic mouse lines expressing Cre recombinase under the control of the mouse peripherin gene promoter. The activity of the Cre recombinase during embryonic development was examined by mating the peripherin-Cre transgenic mice to the knock-in Cre-mediated recombination reporter strain, R26R. Analysis of F1 embryos from this cross showed specific excision of loxP-flanked sequences in the dorsal root ganglia, trigeminal ganglia, and olfactory epithelium, in a pattern very similar to the expression of the endogenous mouse peripherin gene, and the previously reported peripherin-lacZ transgenic mice. Thus, the peripherin-Cre mouse described here will provide a valuable tool for Cre-loxP-mediated conditional expression in the peripheral nervous system. © 2002 Published by Elsevier Science B.V. on behalf of the Federation of European Biochemical Societies.
