The crypt cycle in mouse small intestinal epithelium.
We have used a mutation-induced marker system in the intestine of mice heterozygous at the Dlb-1 locus, which determines the expression of binding sites for the lectin Dolichos biflorus agglutinin, and the frequency of clustering of mutated crypts with time as a means of investigating the frequency of the crypt fission process and the crypt cycle. Whole-mount preparations from heterozygous Dlb-...
متن کاملCVD: the intestinal crypt/villus in situ hybridization database
UNLABELLED The intestinal crypt/villus in situ hybridization database (CVD) query interface is a web-based tool to search for genes with similar relative expression patterns along the crypt/villus axis of the mammalian intestine. The CVD is an online database holding information for relative gene expression patterns in the mammalian intestine and is based on the scoring of in situ hybridization...
متن کاملA low-temperature method for the isolation of small-intestinal epithelium along the crypt-villus axis.
A variety of enzymic and non-enzymic methods to isolate epithelium from the small intestine have been previously published. Sequential fractionation of cells from the villus to the crypt has been reported in some of these papers, which allows the comparative study of terminally differentiated and proliferative cell phenotypes. However, these methods often involve the incubation of tissues at 37...
متن کاملEpithelial hedgehog signals pattern the intestinal crypt-villus axis.
Morphological development of the small intestinal mucosa involves the stepwise remodeling of a smooth-surfaced endodermal tube to form finger-like luminal projections (villi) and flask-shaped invaginations (crypts). These remodeling processes are orchestrated by instructive signals that pass bidirectionally between the epithelium and underlying mesenchyme. Sonic (Shh) and Indian (Ihh) hedgehog ...
متن کاملStudies on Small Intestinal Crypt Epithelium
Small intestinal crypt epithelium obtained from normal fasting humans by peroral biopsy of the mucosa was studied with the electron microscope. Paneth cells were identified at the base of the crypts by their elaborate highly organized endoplasmic reticulum, large secretory granules, and small lysosome-like dense bodies within the cytoplasm. Undifferentiated cells were characterized by smaller c...
