Basic Information

Strain Name
C57BL/6-Col10a1 tm1(iCre) /Bcgen
Stock Number
Common Name
B-Col10a1-iCre Mice
Bcgen (Beijing Biocytogen Co., Ltd)
Related Genes
Col10a1 (collagen, type X, alpha 1); Col10; Col10a-1
Col10a1 iCre (wt/mut)
A F2A-iCre sequence cassette was placed between the coding sequence of exon 3 and 3’UTR of the Col10a1 gene in C57BL/6 ES cells. This strain was maintained on a C57BL/6 genetic background.


The Col10a1 gene encodes a short-chain minor collagen of cartilage which is a direct transcriptional target of RUNX2 during chondrogenesis. In this strain, Cre recombinase expression is under the control of Col10a1 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 Col10a1 expressing cells.
