Abstract:

Background: Periodontal ligament stem cells (PDLSCs) are considered as a type of mesenchymal stem cell that is beneficial target for numerous clinical applications in periodontal tissue regeneration therapy. Materials and Methods: This study examined the effects of dexamethasone (Dex) on human PDLSCs in vitro. PDLSCs obtained from the roots of patient’s teeth were cultured with Dex (0.01 μM), and their proliferation was measured. The osteogenic differentiation was assessed by alkaline phosphatase (ALP) activity and Alizarin Red-S staining for calcium deposition. Results: After the administration of 0.01 μM Dex, the activity of ALP increased significantly. Furthermore, mineralized nodule formation showing the intracellular calcium deposition was significantly higher in the Dex-treated cells than that of the control cells. Conclusion: Collectively, Dex has positive effects on osteogenic differentiation of human PDLSCs in vitro. It is suggested that PDLSCs may serve as a potential material for periodontal tissue regeneration.

Reprogramming by cytosolic extract of human embryonic stem cells improves dopaminergic differentiation potential of human adipose tissue-derived stem cells

The extract of pluripotent stem cells induces dedifferentiation of somatic cells with restricted plasticity. In this study, we used the extract of human embryonic stem cells (hESC) to dedifferentiate adipose tissue-derived stem cells (ADSCs) and examined the impact of this reprogramming event on dopaminergic differentiation of the cells. For this purpose, cytoplasmic extract of ESCs was prepare...

The Potential of Menstrual Blood-Derived Stem Cells in Differentiation to Epidermal Lineage: A Preliminary Report

BACKGROUND Menstrual blood-derived stem cells (MenSCs) are a novel source of stem cells that can be easily isolated non-invasively from female volunteered donor without ethical consideration. These mesenchymal-like stem cells have high rate of proliferation and possess multi lineage differentiation potency. This study was undertaken to isolate the MenSCs and assess their potential in differenti...

Gene expression pattern during osteogenic differentiation of human periodontal ligament cells in vitro

PURPOSE Periodontal ligament (PDL) cell differentiation into osteoblasts is important in bone formation. Bone formation is a complex biological process and involves several tightly regulated gene expression patterns of bone-related proteins. The expression patterns of bone related proteins are regulated in a temporal manner both in vivo and in vitro. The aim of this study was to observe the gen...
