Cancer Research Evaluating Cell Death Using Cell-Free Supernatant of Probiotics in Three-Dimensional Spheroid Cultures of Colorectal Cancer Cells Jina Lee*1,2, Joo-Eun Lee*3, Seil Kim1,4,5, Dukjin Kang1, Hee Min Yoo1 1Microbiological Analysis Team, Group for Biometrology, Korea Research Institute of Standards and Science (KRISS), 2College of Pharmacy, Chungnam National University (CNU), 3Stem Cell Research Center, Korea Research Institute of Bioscience and Biotechnology (KRIBB), 4Convergent Research Center for Emerging Virus Infection, Korea Research Institute of Chemical Technology (KRICT), 5Department of Bio-Analysis Science, University of Science & Technology (UST) Here methods are presented to understand anti-cancer effects of Lactobacillus cell-free supernatant (LCFS). Colorectal cancer cell lines show cell deaths when treated with LCFS in 3D cultures. The process of generating spheroids can be optimized depending on the scaffold and the analysis methods presented are useful for evaluating the involved signaling pathways.
