Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Transgenic Mating System Homozygote x Homozygote (Female x Male) Species laboratory mouse Donating Investigator George Cotsarelis, University of Pennsylvania Generation N10+2F5 (31-DEC-07) Strain Description
Mice hemizygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These transgenic mice express Enhanced Green Fluorescent Protein (EGFP) under the direction of the mouse keratin complex 1, acidic, gene 15 promoter. The high levels of specific transgene expression observed in 'bulge cells' (hair follicle stem cells) allow these cells to be isolated with FACS techniques. This mutant mouse strain may be useful in studies of epithelial stem cells.Strain Development
A transgenic construct containing an Enhanced Green Fluorescent Protein (EGFP) gene under the control of the mouse keratin complex 1, acidic, gene 15 promoter was injected into fertilized B6SJLF1/J mouse eggs. Founder animals were bred to C57BL/6/J mice and backcrossed to the same for a total of ten generations. (Dec 2004).

| Expressed Gene | GFP, Green Fluorescent Protein, jellyfish | ||
| Green Fluorescent Protein (GFP), derived from the jellyfish Aequorea victoria, is a versatile reporter molecule which has found use in many biological applications. The original molecule has been modified in order to enhance its fluorescence intensity (EGFP, enhanced GFP). When utilized in a transgenic construct, tissue expressing sufficient amounts of GFP will fluoresce when exposed to a 488 nm light source. | |||
| Promoter | Krt15, keratin 15, mouse, laboratory | ||
| General Note | This transgenic line is derived from one of eight EGFP-expressing founder mice. Skin of line 3 mice exhibited the strongest fluorescence under ultraviolet illumination, lines 2, 14, 27, 41, 42 and 44 exhibited less fluorescence, and line 13 an intermediate level. Cells from mice of four lines were screened by fluorescence activated cell sorting (FACS); as line 2 high EGFP-expressing cells separated well from other cells in the sample, this line was used for further FACS analyses. | ||
| Molecular Note | The transgene comprises the entire 5.0-kb DNA segment that separates the Krt1-19 and Krt1-15 genes in the mouse genome and that contains the Krt1-15 promoter region joined to the cDNA encoding enhanced green fluorescent protein (EGFP). The Krt1-15 promoter directs expression to the bulge region of the hair follicle; fluorescence activated cell sorting (FACS ) analysis demonstrated that highest EGFP expression occurs in bulge cells showing high surface expression of the epithelial stem cell marker integrin beta 1 (fibronectin receptor beta).
