Flow Cytometry Cancer Stem Cells

According to the cancer stem cell hypothesis a tumor consists of more differentiated highly proliferating cells which constitute the tumor bulk and sustain tumor growth and undifferentiated slow cycling cells with self renewing capacity the so called cancer stem cells cscs 2 4.

Flow cytometry cancer stem cells. Until there are valid identifiers that visualize stem cells in vivo we rely upon flow cytometry to enrich for subpopulations with stem cell function. How cancer stem cells can be identified using flow cytometry. As the seeds for tumorigenesis and metastasis. Flow cytometry can sensitively detect and efficiently sort cells based on fluorescent signals integrated into cellular markers of proteins or dna.

Qrt pcr was used to describe the mesenchymal gene signature of the tumor. Cscs may be responsible for the re. Seventeen paired tumor normal lung samples were collected at the time of surgical excision and processed immediately. It has been broadly applied to assess cell division apoptosis and to isolate cells including stem cells.

This webinar will discuss the advancements in the detection of cscs in primary tumors and in circulation using acoustic flow cytometry together with a new csc marker autofluorescence and other csc markers. In our view clear reporting guidelines could improve reproducibility of stem cell analyses in. Flow cytometry and fluorescence staining was used to quantify cancer stem cell like populations. This report illustrates the application of multidimensional flow cytometry to the identification of candidate stem progenitor populations in non small cell lung cancer and paired normal lung tissue.
