Fully Human Tumor-based Matrix in Three-dimensional Spheroid Invasion Assay Erika Naakka1, Katja Tuomainen1, Henrik Wistrand*1, Miila Palkama*1, Ilida Suleymanova1, Ahmed Al-Samadi1, Tuula Salo1,2,3,4 1Department of Oral and Maxillofacial Diseases, Clinicum, Faculty of Medicine, University of Helsinki, 2Cancer and Translational Medicine Research Unit, University of Oulu, 3Medical Research Center, Oulu University Horspital, 4Helsinki University Hospital Tumor microenvironment is an essential part of cancer growth and invasion. To mimic carcinoma progression, a biologically relevant human matrix is needed. This protocol introduces an improvement for the in vitro three-dimensional spheroid invasion assay by applying a human leiomyoma-based matrix. The protocol also introduces a computer-based cell invasion analysis.
Immunization of Adult Zebrafish for the Preclinical Screening of DNA-based Vaccines Henna Myllymäki*1, Mirja Niskanen*1, Kaisa Oksanen1,2, Mika Rämet1,3,4,5 1BioMediTech Institute, Faculty of Medicine and Life Sciences, University of Tampere, 2MedEngine Oy, 3Department of Pediatrics, Tampere University Hospital, 4Department of Children and Adolescents, Oulu University Hospital, 5PEDEGO Research Unit, Medical Research Center, University of Oulu Here we describe a protocol for the immunization of the adult zebrafish (Danio rerio) with a DNA-based vaccine and demonstrate the validation of a successful vaccination event. This method is suitable for the preclinical screening of vaccine candidates in various infection models.
