mouse strain Insm1tm2Mgn mouse strain RES661 mouse strain Person: Jie Zheng, Chris Stoeckert http://www.betacell.org/resource/view/resource_id/661/ Insm1GFP.Cre mouse strain A mouse strain contains a GFP-Cre fusion protein which replaces the Insm1 coding sequence. These mice express green fluorescent protein (GFP) under control of the Insm1 gene locus. Insm1 is expressed in pancreatic primordium starting at E9.5. Insm1 is also expressed in neural precursor cells and tumors of may be used for lineage tracing of Insm1-positive cells in both wild-type and Insm1-null mice. http://www.betacell.org/resource/view/resource_id/661/ provide the definition of 'Insm1tm1.1Mgn mouse strain' which might be the early version of 'Insm1tm2Mgn mouse strain'. However, we are not clear the difference between two strains. We borrowed the definition of 'Insm1tm1.1Mgn mouse strain'. In the webpage, it has strain name 'Mouse Strain RES661' and common name 'lnsm1GFP.Cre mouse strain'. We added 'lnsm1GFP.Cre mouse strain' as alternative term which is true to 'Insm1tm2Mgn mouse strain' too .
