Description

P0-3.9GFPCre mice express an EGFP-Cre recombinase fusion protein under the control of the Pax6 P0 enhancer. This strain may be useful for genetic manipulations and visualization during the development of retinal and pancreatic lineages.

Detailed description

P0-3.9GFPCre mice express a green fluorescent protein (GFP) fused to a Cre recombinase gene under the control of the murine (paired box 6) Pax6 P0 enhancer. The Pax6 P0 enhancer, located 3.9kb upstream of the Pax6 promoter, drives expression in the retinal and pancreatic primordial cells during early embryonic development. Specifically, expression is seen in retinal horizontal cell precursors and pancreatic endocrine and ductal progenitors. When crossed with a strain containing a loxP site-flanked sequence, Cre-mediated recombination results in deletion of the flanked sequence in these cells.

Development

A transgenic construct containing a green fluorescent protein (GFP) fused to a Cre recombinase gene under the control of the murine (paired box 6) Pax6 P0 enhancer was introduced into FVB donor oocytes. Resulting offspring were bred to 129S mice for one generation, and subsequently to C57BL/6 for one generation. Upon arrival at The Jackson Laboratory, mice were bred to C57BL/6J (Stock No. 000664) for at least one generation to establish the colony.
