Method for determining the anatomical origin of a cell derived from the large intestine using a microarray

摘要

A method to determine the anatomical origin of a cell derived from the large intestine from an individual. The method comprises measuring the level of expression of: (i) The gene detected by Affymetrix probe number 225457_s_at; (ii) The gene detected by Affymetrix probe number 225458_at; or (iii) DKFZP564I1171 in a biological sample from the individual where a higher level of expression of the genes relative to normal distal large intestine control levels is indicative of a proximal large intestine origin.
