Abstract
Rat genomic DNA was isolated by homology with Cdxl, a murine homeogene selectively expressed in intestinal cells of endodermal origin. Southern blot analysis indicated that the rat genome contains a single or a small number of closely related Cdx gene(s). A major 1.7 kb Cdx mRNA was detected in neonate, suckling and adult rats whereas a 6.5 kb mRNA was restricted to sucklings and adults. Both transcripts showed decreasing concentration from the colon towards the proximal part of the small intestine. No obvious correlation could be established with the patterns of expression of transcripts corresponding to markers of cell proliferation and cell differentiation during postnatal development.Keywords
