Bacterial ability to alter the stem cells has important implications for gastrointestinal stem cell biology and H pylori-induced gastric pathology. Lgr5-EGFP-ires-creERT2 mice,11 APCﬂ/ﬂ mice,25 Axin2-lacZ mice,26 and C57B/6 wild-type mice (6–12 weeks old) were used for experiments. Lgr5-EGFP-ires-creERT2 mice were crossed with APCﬂ/ﬂ mice. Cre enzyme activity was induced by intraperitoneal injections of tamoxifen (2 mg/mouse). Murine small intestines To determine the cellular origin of CEA424-SV40-TAg tumours, we performed tracing experiments using Lgr5-EGFP-IRES-creERT2:CEA424-SV40-TAg:ROSA26-tdRFP mice.

Lgr5-EGFP-IRES-. creERT2 mice were generated by homologous recombination in embryonic stem cells targeting an EGFP-IRES-creERT2 cassette to the ATG of We then crossed the stem-cell-specific Lgr5-EGFP-IRES-creERT2 knockin mice to Apcflox/flox mice.

EGFP fluorescence is observed in crypt base columnar cells in small intestine (aka stem cells of the small intestine) and colon. Lgr5 Egfp Ires Creert2, supplied by The Jackson Laboratory, used in various techniques.

Bmi1 + ISCs during homeostasis. We used short-term tamoxifen exposure, for induction of Cre-mediated recombination, to selectively mark Bmi1 + ISCs in vivo. By using the knock-in allele Lgr5EGFP-Ires-CreERT2, we have shown that the cell surface receptor Lgr5 (leucine-rich repeat–containing heterotrimeric guanine nucleotide–binding protein–coupled Throughout the pyloric region of adult stomachs, both the Lgr5-LacZ (Figures 1 A and 1B) and Lgr5-EGFP-ires-CreERT2 (Figures 1 C–1E) reporters were exclusively expressed in cells occupying the very base of the glands. On average, 3.72 ± 1.02 Lgr5-EGFP +ve cells were present in isolated pyloric glands (see Figure 1 E for examples). Lgr5-EGFP-Ires-CreERT2;R26R-Confetti double transgenic mice were treated with vehicle (n = 8) or G007-LK (n = 5) and tamoxifen according to the two administration schemes outlined in Fig. 1d, f. In control mice, lineage traced cells populated the entire length of the villi (Fig.

In contrast, only 1.7 ± 0.30% of Bmi1+ ISCs, identiﬁed by the crypt Rosa-YFP+ signal after 1.5-d tamoxifen exposure in Bmi1-CreER; Rosa26-YFP mice, incorporated EdU (Fig. 1 A–F and N). To examine the relative contribution of Lgr5 vs. Bmi1 ISCs to tissue regeneration under steady-state conditions Symbol: Lgr5 tm1(cre/ERT2)Cle: Name: leucine rich repeat containing G protein coupled receptor 5; targeted mutation 1, Hans Clevers: MGI ID: MGI:3764660: Synonyms: Lgr5-cre, Lgr5CREER, Lgr5-creERT, Lgr5-CreERT2-IRES-EGFP, Lgr5-EGFP, Lgr5 EGFP-IRES-creERT2, Lgr5-EGFP-IRES-creERT2, Lgr5 tm1(cre/ESR1)Cle To determine the cellular origin of CEA424-SV40-TAg tumours, we performed tracing experiments using Lgr5-EGFP-IRES-creERT2:CEA424-SV40-TAg:ROSA26-tdRFP mice. Following tamoxifen induction, it was possible to efficiently trace the progeny of Lgr5-expressing cells in gastrointestinal tissue via red fluorescent protein (RFP) expression. stochastically initiated using the Lgr5-EGFP-Ires-CreERT2 allele in conjunction with the R26R-Confetti reporter.

Tumors were then flow-sorted into fractions of epithelial cells that expressed high or low levels of Lgr5 and were molecularly characterized using gene expression profiling and array comparative genomic hybridization. Lgr5 EGFP‐Ires‐CreERT2 knock‐in mice (Barker et al., 2007) and Rosa26‐LacZ mice were obtained from the Jackson Laboratory. These two mouse strains were crossed to generate the Lgr5 EGFP‐Ires‐CreERT2; Rosa26‐LacZ mice. All animals were housed in a facility with a 12‐h light/12‐h dark cycle. Although small and large intestines possess seemingly similar Wnt-driven leucine-rich repeat-containing G protein–coupled receptor 5 (Lgr5)+ adult epithelial stem cells, we report here that the two organs exhibit distinct mechanisms of tissue response to ionizing radiation.

When these mice mice are bred with mice containing a loxP-flanked sequence of interest, tamoxifen-inducible, Cre-mediated recombination will result in deletion of the floxed sequences in the Lgr5-expressing cells of the offspring.

ZERO BIAS - scores, article reviews, protocol conditions and more To assess whether all epithelial tumours of the gastrointestinal tract are derived from LGR5-positive stem cells, we crossed Lgr5-EGFP-IRES-creER(T2) mice, which express EGFP and Cre recombinase driven by the Lgr5 promoter, with CEA424-SV40-TAg mice, which develop pyloric neuroendocrine carcinomas of epithelial origin. Taste progenitor cells in the CVP express LGR5 and can be isolated via EGFP fluorescence-activated cell sorting (FACS) from mice carrying an Lgr5 EGFP-IRES-CreERT2 allele. Sorted cells are plated onto a matrix gel-based 3D culture system and cultured for 12 days.
