文摘

Stem cell technology has been a great hope for the treatment of many common tissue regeneration-related diseases. Therefore, the main challenge in hard tissue engineering is to make a successful combination of stem cells and efficient inductors such as biomaterials or growth factors, in the concept of stem cell conversion into odontogenic cell. Even though lactoferrin has been reported to promote bone growth in vivo, the molecular mechanism of teeth formation has not been elucidated yet. Different concentrations of lactoferrin were prepared for the analysis of cell toxicity and differentiation evaluations. The odontogenic differentiation of human tooth germ stem cells (hTGSCs) was assessed by gene expression analysis, determination of protein levels in odontogenic differentiation-related protein, measuring alkaline phosphatase (ALP) activity, mineralization, and calcium deposit levels. Lactoferrin-treated group showed the highest ALP activity as opposed to the other groups which were untreated. In addition, the gene expression levels as well as the protein levels of odontogenic factors were found to be high in compared to the control groups. In the current study, it is shown for the first time that there is a significant increase in odontogenic differentiation capacity in hTGSCs when lactoferrin is applied in vitro. The study offers a considerable promise for the development of pulp regeneration by using stem cell technology combined with lactoferrin in functional tooth tissue engineering.
