Adjunct Professor, PhD, Chief Scientist

Dr. Bettina Mannerström received her Master’s degree majoring in Cell Biology in 2005 and her PhD in Tissue Engineering 2009 from the University of Tampere. She has served as a senior scientist in the Adult Stem Cell group at BioMediTech at the University of Tampere 2009 - 2015. Her research focus has been on translational medicine to characterize adult stem cells and to optimize their culturing conditions to meet the requirements set for clinical cell therapy. Currently she is the Chief Scientist in the department of Oral and Maxillofacial Diseases at the University of Helsinki, focusing on the role of exosomes in stem cell safety and efficacy studies. She is an author in 31 high level scientific publications in the field.



MannerströmLindroos (née)

PhD Student, DDS 

Dr.Kornilov attended University of Tartu for his undergraduate studies, where he demonstrated strong interest in research and surgery. That resulted in a project about stem cells and Platelets-Rich-Plasma usage in regenerative medicine. Being a full-time licensed doctor helped him to understand the major problems of Dentistry – bone healing. This interest has led dr. Kornilov into continuation of his education at University of Helsinki where he is pursuing his Doctorate degree in Translational Research on Oral and Maxillofacial sciences since 2016. During his post-graduate studies at Helsinki University he is doing extensive research in developing new methods for bone remodeling and safety of it. 

Roman Kornilov is an active member of the following organizations: 

FINDOS – Finnish Doctoral Program in Oral Sciences (Doctoral students’ representative on a National level) 
Apollonia – Finnish Dental Society

PhD Student, DDS

The doctoral student currently works as a visiting researcher in TMC group. In 2006, he graduated at University of Tanta, Faculty of Dentistry in Egypt; where he was able to join the department of Oral and Maxillofacial Surgery as a resident and then as a demonstrator, thus allowing him to get a solid knowledge in the field. In his M.D.Sc thesis he concentrated on the evaluation of the role of autogenous bone-marrow derived mesenchymal stem cells transplantation in the repair of mandibular bone defects experimentally in rabbits, which was a co-operative work of Oral and Maxillofacial Surgery Department of Tanta Dental School and the Histology Department-Tissue Engineering Unit- of The School of Medicine, Tanta University. His previous work endowed him an intense experience on the in vitro cell culturing of MSCs which is vital for current projects.



PhD Student, MSc

Snehadri graduated with a Master's degree in Molecular Biosciences (Biochemistry) from the University of Helsinki in 2018. In his Master's thesis, he investigated the effects of different lipoproteins on the formation of platelet-derived EVs. He has also worked in the EV Core facility in Viikki, which gave him a good level of experience in the EV field. In his current research, Snehadri is investigating EVs in the osteosarcoma microenvironment and also working on developing  a 3D osteosarcoma model. 



Adjunct Professor, PhD 

Dr. Sippy Kaur received her Master’s degree in 2003 majoring in microbiology from University of Helsinki. She received her PhD on Cancer Genetics in 2007 from University of Helsinki. She is an adjunct professor of Cancer Genetics and Epigenetics since 2013 and has served as senior researcher at University of Helsinki at Department of Obstetrics and Gynecology (2007-2008) and at Department of Medical Genetics (2009-2014). Her research focus has been to investigate the genetic and epigenetic markers involved in the cancer initiation and its translational application. Currently she is working in Department of oral and maxillofacial diseases investigating the role of exosomes in stem cells differentiation and its translational applications. She is a main author of 22 high level scientific publications in the field.



Assistant Professor, MD, DDS, PhD

Dr. Olli-Pekka Lappalainen received his Licentiate’s degree in Dental Medicine in 1998, Specialist in Oral and Maxillofacial Surgery degree in 2009, Licentiate of Medicine degree in 2011 and PhD in Medicine 2016 from the University of Oulu. His PhD thesis focused on tissue engineering by using autologous bone grafts, stem cells, growth factors and biomaterials in the treatment of large calvarial tissue defects. He has been working on regenerative technologies with tissue cultures, reconstructive surgery applications and on osteosarcoma research, the latter being also his current research interest. He is an author in 6 high level scientific publications in his interest field. 





Doctor of Dental Science, Licentiate of Medicine (DDS, MD), resident doctor in oral and maxillofacial surgery

Dr. Johanna Uittamo received her Licentiate’s degree in Dental Medicine in 2008, PhD in Dental Science in 2012 and Licenciate’s degree in Medicine 2016 from the University of Helsinki. Her PhD thesis focused on oral cancer and the role of acetaldehyde in the etiology of the disease. She has been working with oral microbes, isolating and culturing them and analyzing the ability of the microbes to produce acetaldehyde. The current focus is to find out the role of exosomes in the oral cancer, in both sarcomas and carcinomas. She is an author of 9 high level scientific publications in the field.
