Anaerobiosis and Stemness

Zoran Ivanovic is Scientific Director of French Blood Institute for the regions of Aquitaine and Limousin (Bordeaux, France) and Head of R&D Cell Engineering Research Laboratory. He is also the Group Leader (“Adult stem cells”) in UMR 5164 CNRS/University of Bordeaux. He received his MD, MSc (system and comparative physiology) and DSc (experimental hematology) degrees at Belgrade University, and the highest French Degree “HDR” (Habilitation à Diriger les Recherches) at Bordeaux 2 University. He specialized in Transfusion (Bordeaux 2 University) and in Cell Therapy (Paris 7 University). Research Professor at Institute for Medical Research of Belgrade University, former Associate Professor of Hematology at Limoges and Bordeaux Universities (1999-2002), he has been, since 2011, guest professor at the Medical Faculty of Niš University. Dr Ivanovic obtained several grants in the field of cord blood and adult stem cell research. His group studies the anaerobic proliferation of stem cells and develops clinical-scale ex-vivo expansion procedures, pre-conditioning of stem cells for transplantation as well as new approaches of stem and progenitor cell conservation in hypothermia. He published 123 articles and book chapters, realized 150 meeting communications and supervised several PhD and master theses. He serves as Academic Editor of PLoS One as well as reviewer for many scientific journals. Marija Vlaski Lafarge is staff scientist in R&D Cell Engineering Research Laboratory of French Blood Institute for the regions of Aquitaine and Limousin (Bordeaux, France) and in UMR 5164 CNRS/University of Bordeaux. She obtained her PhD degree at Faculty of Sciences (Cell physiology), University of Belgrade, Serbia. Her scientific activity is devoted to stem cell metabolism and physiology studies. Dr. Vlaski Lafarge presented her work in articles, book chapters and meeting communications. She participated in the grants preparation, reviewed several scientific manuscripts, and governed many student’s research projects.

"...provides the key for understanding and predicting stem cell behavior in vivo and ex vivo, which is of paramount importance for the cell engineering and anti-cancer strategies." --Serbian Archives of Medicine"The “evolutionary stem cell paradigm”of Z. Ivanović and M. Vlaški provides the key for understanding and predicting stem cell behavior in vivo and ex vivo, which is of paramount importance for the cell engineering and anti-cancer strategies. The concept of anaerobiosis and stemness presented in this unique book implies the epigenetic missing link in stem cells behavior. The evolutionary paradigm described, although partly hypothetical, is important for understanding developmental biology." --Professor Pavle Milenković, MD, PhD, President of the Academy of Medical Sciences, Serbian Medical Society
