The embryonic lethality of mice with conventional global knockout of Ccn1 (Cyr61) precludes analysis of Ccn1 functions in late embryonic development or in adulthood. To circumvent this limitation, we have generated conditional knockout mice that allow cell type-specific deletion ofCcn1, and constructed an allelic series of Ccn1 knockin mice that express CCN1 defective for binding specific integrins in lieu of the wild type protein. Here we describe the construction of these mice and discuss how analysis of these animals can provide unique insights into Ccn1 functions mediated through specific integrin receptors. It is anticipated that future analysis of mice carrying specific mutations in genes of the Ccn family will be greatly facilitated by application of the CRISPR/Cas9 gene editing methodology.
