    Biography
      Dr. Bruno Sainz is a Ramón y Cajal Researcher, with co-appointments in the Department of Biochemistry at the Autónoma University of Madrid, the Department of Cancer Biology at the Instituto de Investigaciones Biomédicas "Alberto Sols" CSIC-UAM and in the Chronic Diseases and Cancer Area of the Ramón y Cajal Institute for Health Research. Dr. Sainz obtained his PhD in Microbiology and Immunology from Tulane University in 2005, and began working on cancer in 2011 after joining the Spanish National Cancer Research Centre as a Staff Scientist. He currently heads the Cancer Stem Cells and Tumor Microenvironment group, focusing on the study of cancer stem cells (CSCs) and the fibroinflammatory microenvironment in pancreatic ductal adenocarcinoma (PDAC). His lab is running a combined basic and translation research program, which synergistically combines studies on the biology of mouse and human CSCs, including their in vivo microenvironment, in order to enhance our understanding of the regulatory machinery of CSCs. Specifically, his laboratory is pursuing: 1) The identification and characterization of new biomarkers for the detection of CSCs from different solid tumors; 2) The identification of proteins that govern key CSC phenotypes, such as "stemness", epithelial to mesenchymal transition (EMT), oxidative phosphorylation and chemoresistance; and 3)Comprehensive understanding of the cellular make-up of the CSC niche and the more complex tumor microenvironment, specifically the role of tumor-associated macrophages (TAMs) in promoting CSCs, with respect to the different environmental proteins they can secrete in response to cues from the tumor and how these proteins alter the function of the CSCs at the level of EMT and chemoresistance. The group is using state of the art in vitro (primary PDAC cultures) and in vivo (patient-derived xenograft and genetically engineered mouse models) systems along with acoustic flow cytometry, to better understand the role of CSCs in cancer.

    Abstract

    DATE: December 05, 2018
    TIME:  07:00am PST

    What is desperately needed are methods to detect cells that cause metastasis–known as cancer stem cells (CSC), a subpopulation of tumor cells with “stem” like, chemoresistant and unlimited self-renewal properties. 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.

    Learning Objectives:

    •  How cancer stem cells can be identified using flow cytometry
    •  What factors that should be considered when using flow cytometry to identify cells from tumors and from blood
    • About sample preparation and choosing CSC markers
