Development
An F2A-iCre sequence cassette was placed between the coding sequence of exon 2 and 3’UTR of the Sp7 gene in C57BL/6 ES cells. This strain was maintained on a C57BL/6 genetic background.

Description

The Sp7 gene is a C2H2-type zinc finger transcription factor of the SP gene family and putative master regulator of bone cell differentiation. In this strain, Cre recombinase expression is under the control of Sp7 promoter. When crossed with a strain containing a loxP site-flanked sequence of interest, Cre-mediated recombination results in deletion of the flanked sequence in Sp7 expressing cells.
