Normal colon top vs colon crypts


ABSTRACT: The study is to define the genetic programs of human colonic cell differentiation, and to identify candidate markers for colonic stem cells and stem cell niche The study assayed the expression of 9 paired normal colon top versus crypts. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Using regression correlation

Human colonic epithelial cell renewal, proliferation, and differentiation are stringently controlled by numerous regulatory pathways. To identify genetic programs of human colonic epithelial cell differentiation in vivo as well as candidate marker genes that define colonic epithelial stem/progenitor cells and the stem cell niche, we applied gene expression analysis of normal human colon tops and basal crypts by using expression microarrays with 30,000 genes. Nine hundred and sixty-nine cDNA clon  ...[more]
