Abstract (original English)
In this study, stable, homogenous and thin titania dioxide coatings (TiO2) on stainless steel substrate doped with two dosages of bioactive sphingolipids S1P were fabricated using the sol-gel method. S1P belongs to a family of sphingolipids acting as important extracellular signaling molecules and chemoattractants. This study investigated the effect of TiO2, doped with S1P in two different dosages on cellular response as well as osteogenic differentiation potential of human adipose derived multipotent stromal stem cells (hASC). The authors have shown that S1P mediates hASCs morphology, proliferation activity and population doubling time in a dose-dependent manner. They have also demonstrated that functionalization of TiO2coating with a higher dosage of S1P, i.e. 80 ng/ml [(TiO2/S1P(CII)] activated both S1PR type 1 and type 2 on mRNA level. The results indicated an increase in secretion of BMP-2, Osteopontin and Osteocalcin by osteoblasts progenitor when cultured on [TiO2/S1P(CIIm)]. In addition, the authors observed the highest extracellular matrix mineralization as well as osteonodules formation by the osteoblasts precursors when cultured onto [TiO2/S1P(CIIm)].
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • This is a narrative review: it collects no new patient data and does not systematically appraise evidence quality.
