Human dental pulp stem cells cultured in xenogeneic-free supplemented media Summary Introduction: The topic of the study is the cultivation of dental pulp stem cells (hDPSCs) in a xenogeneic-free culture medium. It is not permissible to use cells upon growing under the influence of xenogeneic (extraneous) substances in human clinical practice. The most frequently used in cultivation of hDPSCs is fetal calf serum (FCS/FBS). Unfortunately, these supplements are widespread in hMSCs cultivation, and all gold standard hMSCs properties were postulated in cells cultivated using these supplements. This raises the basic question if and how xenogeneic blood derivatives affect the properties of cells and their growth characteristics. There are two options for replacing these xenogeneic substances in the culture medium: the so-called serum-free media, or human blood supplements, ideally autologous ones. The conducted research was aimed at identifying the effects of xenogeneic and human blood supplements on basic hDPSCs characteristics that are fundamental to introduce the cell therapy into regular medical practice. Method: By culturing 12 hDPSC lines obtained from adult, deciduous, and natal teeth in 12 different culture media, we investigated the effect of FCS, human blood derivatives, i.e., blood plasma (HP), and...

Differentiation potential of human dental pulp mesenchymal stem cells
Vacková, Kristýna ; Voltrová, Barbora (advisor) ; Steklíková, Klára (referee)
Nowadays, dental pulp mesenchymal stem cells (dpMSC) are very popular amongst stem cells used for the study of cell therapy and regenerative medicine, due to their broad differentiation potential and simplicity of isolation. They are isolated from third molars which are often removed during routine surgeries in dentistry and would otherwise be discarded without any benefit as a waste material. Moreover, there are no ethical problems connected with their use. DpMSC fulfil all criteria established for mesenchymal stem cells, proliferate sufficiently and have a long lifespan in vitro. Besides their ability to differentiate into osteogenic, adipogenic and chondrogenic lineage, dpMSC are capable to differentiate into neurogenic, myogenic and hepatogenic lineage and into melanocytes and endothelial cells. Especially, dpMSC are used on animal model organisms for in vivo regeneration of tooth, bone, muscle, neuronal and liver tissue. Currently, several clinical trials are investigating the regenerative potential of dpMSC in humans. Apart from application in stomatology for tooth or bone regeneration, they can also be used for the treatment of the neurogenic diseases and for many other applications, on account of their origin in neural crest. The aim of this work was to write a literature review focused on...
