title: Proliferative Capacity and Phenotypical Alteration of Multipotent Ecto-Mesenchymal Stem Cells from Human Exfoliated Deciduous Teeth Cultured in Xenogeneic and Allogeneic Media.
abstract: Foetal calf serum (FCS) is a standard supplement used in media for in vitro stem cell cultivation. This xenogeneic supplement remains widely used for its favourable growth-promoting properties and ease of accessibility; however, it is inherently not fit for human medicine due to its capacity to temper with the cultured cell quality. For this reason, the international community encourages research and development of allogeneic sera, which would expunge this issue. This study aims to investigate the differences in proliferative capacity, phenotype, and differentiation capacity of ecto-mesenchymal stem cells from human exfoliated deciduous teeth (SHED) cultured in vitro in media supplemented with allogeneic and xenogeneic sera. To address these aims, we cultured three lineages of stem cells in media supplemented with FCS in a concentration of 2% + growth factors; human blood plasma and platelet-rich plasma in concentrations of 2% + growth factors, and 10%. Here, the xenogeneic cultivation was considered as a basis for comparison because this serum is commonly used in studies concerning ecto-mesenchymal stem cells. The study shows that multipotent ecto-mesenchymal SHED can be feasibly cultivated in media where the xenogeneic FCS is substituted by allogeneic platelet-rich plasma, considering the cultured cell proliferative and differentiation capacities. We have also proved that different sera impact the cultured cells' phenotype differently, which has major implications for previous and future stem cell research and regenerative therapy.
