MOLECULAR MARKER FOR CANCER STEM CELL

摘要

Disclosed are: a molecular marker for detecting a cancer stem cell in a cell population of interest, which can be detected in a cancer stem cell included in the cell population of interest but cannot be detected in a cancer cell that is not a cancer stem cell or a normal cell; a method for determining the presence or absence of a cancer stem cell in a cell population of interest by using the molecular marker as an indicator; a kit for determining the presence or absence of a cancer stem cell, which comprises at least a reagent for detecting the molecular marker; a polypeptide encoded by the molecular marker; an antibody which can recognize an epitope of a gene expression product derived from the molecular marker; and a nucleic acid which can inhibit the expression of the molecular marker.
