The anti-galectin-4 or -6 staining is shown in red, the anti-Muc-2 in green, and the DAPI-stained Is {therefore|consequently|as a result|for that reason|thus|hence nuclei is in blue. The anti-galectin-4 or -6 staining is shown in red, anti-Muc2, which specifically stains mucus within the goblet cells, in green, along with the DAPI-stained nuclei in blue. The inset in 2c is an enlargement in the filiform papilla for which the contrast has been enhanced, as indicated by the arrow. The inset in 2k represents an enlargement of two other mucus vesicles from a unique section of your exact same sample.3261)Galectin-4/-6 Expression in the Digestive TractHouzelstein et al.Figure three. Differences inside the subcellular localization of galectin-4 and galectin-6 inside the 129/Sv background. Expression of galectin-4 (3a) and galectin-6 (3b) in samples of duodenum fixed by immersion into the fixative, as opposed to via intracardiac perfusion, as inside the rest with the figures. In 3a, the arrowheads point toward endosomes in the enterocytes; the arrow points toward galectin-4 aggregates at the base on the secretion granule of a goblet cell, and the double arrow points toward galectin-4 and Muc-2 constructive secretory granules also in goblet cells. In 3c, the arrows point toward an accumulation of galectin-4 protein in enterocyte apical membrane, and the double arrows point toward round shaped cells at the apex in the villus. In 3d, the arrows point toward galectin-6 constructive nuclear granules in enterocytes, plus the arrowheads point toward massive nuclear granules in goblet cells. In 3e, the arrowheads point toward galectin-4-decorated bacteria present inside the colonic lumen. In 3f, the asterisks label galectin-6expressing enteroendocrine cells, and the inset shows an enlargement of one of such cells. The anti-galectin-4 or -6 staining is shown in red, the anti-Muc-2 in green, and the DAPI-stained nuclei is in blue. Scale bars = 40 . L = lumen; LP = lamina propria. Precisely the same settings and exposure instances have been applied for all photographs. The levels had been altered for the inset in 3c as a way to improve the enterocytic nuclear staining (arrowhead).rinsed twice in PBS (BD0435, Euromedex, France). Sections were unmasked (94C, 40 mins, Dako Target Retrieval Remedy High pH, S3308), rinsed in PBS, after which blocked for 1 hr in five donkey serum (UP77719A, Interchim, France) in PBS within a humid chamber. Sections have been then incubated overnight at 4C in a humid chamber within the main antibody solutions (in PBS, five donkey serum).The sections have been washed three instances, for five min each time, in PBS, incubated for 1 hr at area temperature within the secondary antibody options (in PBS, 5 donkey serum), washed once more 3 times in PBS, for 5 min every single. Visualization of cell nuclei was achieved by incubating the sections for ten min in a 1:4000 DAPI resolution in a humid chamber and washing the sections 3 instances in PBS forFigure two. Expression of galectin-4 and -6 along the digestive tract. Expression of galectin-4 (two left columns) or galectin-6 (right column) inside the C57BL/6J (left column) or 129/Sv (two correct columns) background along the digestive axis (tongue, stomach, Br ner's gland, duodenum, ileum, colon). In 2a and 2c, the white dashed line marks the limit involving the lamina propria and the lingual epithelium.
