Short and long-term blockades of adenosine 2A, 5-HT2A, and 5-HT7 receptors induce apoptosis, reduce proliferation, and show differential effects on miR-27b-3p expression in neuroblastoma cell lines.

The first of our aims in this study was to investigate the effects of 5-HT2AR, 5-HT7R, and A2AR blockades on miR-27b-3p expression in the short and long-term in neuroblastoma cells. Our second aim was to reduce the expression of pERK and suppress proliferation by blocking the 5-HT2AR with ketanserin. Our third aim was to reduce the expression of pAKT and induce apoptosis by blocking the A2AR and 5-HT7R with MSX3 and SB269970.

Mesenchymal stem cell-derived conditioned medium and Methysergide give rise to crosstalk inhibition of 5-HT2A and 5-HT7 receptors in neuroblastoma cells.

Objective: (s): We aimed to investigate the effects of mesenchymal stem cell secretome and methysergide combination on 5-hydroxytryptamine 2A, (5-HT2AR), 5-hydroxytryptamine 7 (5-HT7R), adenosine 2A (A2AR) receptors and CD73 on neuroblastoma cell line and how they affect biological characteristics. Methysergide was used as a serotonin antagonist on the neuroblastoma cells.

Materials And Methods: Human dental pulp-derived stem cells (hDPSCs) used to obtain conditioned medium (CM).

Effects of non-steroidal anti-inflammatory drug (ibuprofen) in low and high dose on stemness and biological characteristics of human dental pulp-derived mesenchymal stem cells.

Purpose: The effect of ibuprofen, an NSAID, on biological characteristics such as proliferation, viability, DNA damage and cell cycle in dental pulp derived stem cells (DPSCs) can be important for regenerative medicine. Our aim is to investigate how low and high doses of ibuprofen affect stem cell characteristics in DPSCs.

Materials And Methods: DPSCs were isolated from human teeth and characterized by flow cytometry and differentiation tests.

Effects of combination TGF-B1 transfection and platelet rich plasma (PRP) on three-dimension chondrogenic differentiation of rabbit dental pulp-derived mesenchymal stem cells.

: The aim of this study was to evaluate the effects of standard culture medium and chondrogenic differentiation medium with PRP on chondrogenic differentiation of rabbit dental pulp-derived mesenchymal stem cells (rabbit DPSCs) that are transfected with transforming growth factor-beta 1 (TGF-B1) gene, based on the hypothesis of TGF- B1 and PRP can be effective on the chondrogenesis of stem cells. : Rabbit DPSCs were characterized by using flow cytometry, immunofluorescent staining, quantitative Real Time Polymerase Chain Reaction (qRT-PCR) and differentiation tests. For the characterization, CD29, CD44 and CD45 mesenchymal cell markers were used.

Comparison of the effect of postoperative care agents on human gingival fibroblasts: a preliminary study.

Purpose: The aim of this study is to compare effects of postoperative care agents; chlorhexidine, octenidine dihydrochloride and hyaluronic acid on human gingival fibroblasts' viability, proliferation, apoptosis and migration.

Materials And Methods: After cell culturing; chlorhexidine, octenidine dihydrochloride and hyaluronic acid solutions were applied on cells and nothing was applied for control group. The cells were monitored to investigate cytotoxicity; the percentage of apoptotic, living and dead cells at the time of 24, 48, and 72 hours (h).

Effects of TGF-1 Overexpression on Biological Characteristics of Human Dental Pulp-derived Mesenchymal Stromal Cells.

Objective: The aim of our study was to investigate the effect of Transforming growth factor beta-1 (TGF-1) gene therapy on the surface markers, multilineage differentiation, viability, apoptosis, cell cycle, DNA damage and senescence of human Dental Pulp-derived Mesenchymal Stromal Cells (hDPSC).

Methods: hDPSCs were isolated from human teeth, and were cultured with 20% Fetal Bovine Serum (FBS) in minimum essential media-alpha (-MEM). TGF-1 gene transfer into hDPSCs was performed by electroporation method after the plasmid was prepared.

Comparative Analysis of Mesenchymal Stem Cells from Bone Marrow, Adipose Tissue, and Dental Pulp as Sources of Cell Therapy for Zone of Stasis Burns.

: The implantation of mesenchymal stem cells (MSCs) has been shown to exert benefits for the survival of the zone-of-stasis. However, the clinical experience indicates the importance of selecting the right source and type of stem cells. Therefore, we planned the current study to perform a quantitative comparison of MSCs isolated from three different sources to provide information useful in selection of the optimal source and to see whether critical mechanisms are conserved between different populations.
