Abstract:
암 줄기 세포 또는 순환 종양 세포 분리용 조성물 및 키트, 및 생물학적 시료 중 암 줄기 세포, 순환 종양 세포를 분리하는 방법, 및 전이성 암의 진단 방법이 제공된다. 이를 이용하면 암 줄기 세포 또는 순환 종양 세포 분리를 효율적으로 분리 또는 검출하고, 전이성 암을 정확도와 민감도가 높게 진단할 수 있다.
Abstract:
PURPOSE: A biomarker for diagnosis of cancer is provided to be able to efficiently detect and isolate the cancer stem cell or the epithelial-mesenchymal transited circulating tumor cell. CONSTITUTION: A biomarker for detecting the cancer stem cell or the epithelial-mesenchymal transited circulating tumor cell includes Caveolin-1 of which the expression relatively increases in the cancer cell compared to the normal cell. A kit for detecting the cancer stem cell or the epithelium-mesenchymal transited circulating tumor cell includes Caveolin-1 or an antibody specifically binding to its fragment, or its antigen binding fragment. A method of isolating the cancer stem cell or the epithelium-mesenchymal transited circulating tumor cell comprises a step of detecting the cancer stem cell or the epithelium-mesenchymal transited circulating tumor cell in which Caveolin-1 is expressed on the cell surface from a biological sample; and a step of isolating the detected cancer stem cell or epithelium-mesnchymal transited circulating tumor cell from the biological sample.
