Abstract

The data on the immunohistochemical analysis of conditional Notch ligand knockout mice is presented. Targeted deletion of Jag1, Dll1, Dll4, or Dll1 plus Dll4 in Lgr5+ve cells was induced by a Cre-mediated gene recombination, and differentiation or proliferation of the intestinal epithelial cells was examined by immunohistochemistry. These data are the extension of the data presented and discussed in the paper entitled “Indispensable role of non-canonical Notch signaling in the proliferation of Apc-deficient intestinal tumors“ (Nakata et al., Submitted for publication) [1].

2. Experimental design, materials, and methods

2.1. Mice

All the animal experiments were approved by the Animal Welfare Committee of Tokyo Medical and Dental University (Approval no. 016326A). All animal procedures were carried out in compliance with the institutional standards for use of laboratory animals. Lgr5-EGFP-ires-CreERT2 mice (Stock No. 008875) and ROSA26-tdTomato mice (Stock No. 007909) were purchased from The Jackson Laboratory (Bar Harbor, Maine, USA). Jag1-floxed (Jag1fl/fl) mice [2], Dll1-floxed (Dll1fl/fl) mice [3] and Dll4-floxed (Dll4fl/fl) mice [4] have been previously described. These mice were housed in the animal facility of Tokyo Medical and Dental University, and crossed to generate LGR5-EGFP-ires-CreERT2; ROSA26-tdTomato; Jag1fl/fl (Jag1fl/fl) mice, LGR5-EGFP-ires-CreERT2 ROSA26-tdTomato; Dll1fl/fl (Dll1fl/fl) mice, LGR5-EGFP-ires-CreERT2; ROSA26-tdTomato; Dll4fl/fl (Dll4fl/fl) mice, and LGR5-EGFP-ires-CreERT2; ROSA26-tdTomato; Dll1fl/fl; Dll4fl/f (Dll1fl/fl; Dll4fl/fl) mice. LGR5-EGFP-ires-CreERT2; ROSA26-tdTomato mice served as the control (Control). Cre-mediated gene recombination was induced by intraperitoneal injection of tamoxifen (TX, 2 mg/body) for 5 consecutive days, as previously described [1] [5].

2.2. Antibodies

The primary antibodies used are as follows: anti-Dll1 (1:500, AF5026, R&D systems, Minneapolis, USA), anti-Dll4 (1:500, AF1389, R&D systems, Minneapolis, USA), anti-RFP (1:500, PM005, MBL, Nagoya, Japan), anti-tdTomato (1:500, AB8181-20, SIGEN, Cantanhede, Portugal), anti-Hes1 (1:80000, kindly provided by T. Sudo, Toray, Kanagawa, Japan) [6], anti-Ki67 (1:50, TEC-3, DAKO, Glostrup, Denmark), anti-MUC2 (1:100, SantaCruz Biotechnology, Texas, USA), anti-CgA (SP-1, Diasorin, Saluggia, Italy), anti-DCAMKL1 (1:100, AP7219B, Abgent, San Diego, USA), and anti-Lysozyme (1:1500, EC3.2.1.17, DAKO, Glostrup, Denmark).

2.3. Immunohistochemistry of mouse intestinal tissue samples

Immunohistochemistry of mouse intestinal tissues was performed as previously described [5], [7]. Sections (8 μm) were prepared for the analysis. Antigen retrieval in citrate buffer was required for staining Dll1, Dll4, CgA and Hes1. Tyramide signal amplification was used for the immunofluorescent detection of Dll1, Dll4, CgA and Hes1. Stainings were visualized by the standard Avidin-biotin complex (ABC) method, or by secondary antibodies and tyramide substrates conjugated with Alexa-594 or Alexa-488 (Molecular Probes, California, USA). Tissues were counterstained by 4׳,6-diamidino-2-phenylindole (DAPI) or by hematoxylin. Data were collected using an epifluorecent microscope (BZ-X700, KEYENCE, Tokyo, Japan).
