The results of our investigations have been published in respected international journals and this is the way for affirmation of Slovenian science in the field of cancerogenesis. We transvere the knowledge from our investigations to the medicine, dental medicine and pharmacy students on undergraduate as well as on graduate level. Through the closely cooperation with oncologists, the cancer patients mostly gain from the results of our research. In Slovenian field we initiate few new technics in cell culture, cultivation of multicellular spheroids as well as new histological technics. The researchers from other research progam groups as well as foreign researchers take an interest in our investigations. Joint research interests make possible the bilateral research projects between our research group in the Institute of Histology and Embryology and researchers from Department for the Molecular Biology and Oncology from the Institute Curie Paris, France and researchers from Department of Anatomy, Case Western Reserve University Cleveland, USA.
