Tumors contain a small population of cancer stem cells (CSC) proposed to be responsible for tumor maintenance and relapse. Aldehyde dehydrogenase 1 (ALDH1) activity has been used as a functional stem cell marker to isolate CSCs in different cancer types. This study used the Aldefluor assay and fluorescence-activated cell sorting (FACS) analysis to isolate ALDH1high cells from five human sarcoma cell lines and one primary chordoma cell line. ALDH1high cell...

Chordomas are rare, low to intermediate grade malignant bone tumors of the axial skeleton. Current treatment options are limited to surgical procedures as chordomas are largely resistant to conventional radiation and chemotherapy. Cell lines are valuable tools to explore molecular mechanisms involved in tumorigenesis and they have a fundamental impact on the development of new anticancer agents. We established a novel chordoma cell-line, MUG-Chor1, from a recurrent morphologic...
