Published: January 2020

Ten-eleven translocation (TET) methylcytosine dioxygenases are enzymes that catalyze the demethylation of 5-methylcytosine on DNA. Through global and site-specific demethylation, they regulate cell fate decisions during development and in embryonic stem cells by maintaining pluripotency or by regulating differentiation. In this Primer, we provide an updated overview of TET functions in development and stem cells. We discuss the catalytic and non-catalytic activities of TETs, and their roles as epigenetic regulators of both DNA and RNA hydroxymethylation, highlighting how TET proteins function in regulating gene expression at both the transcriptional and post-transcriptional levels.

Objective: Within the scope of this research, the long-term effects of experimental blunt head trauma on immature rats and MK-801 administered acutely after trauma on the brain tissue will be examined. In addition, the impact of trauma and MK-801 on Nestin and CD133, which are essential stem cells, will be evaluated by immunohistochemical and ELISA methods.

Methods: In this study, the contusion trauma model was used.

Advances in liver organoids: replicating hepatic complexity for toxicity assessment and disease modeling.

Stem Cell Res Ther

The lack of in vivo accurate human liver models hinders the investigation of liver-related diseases, injuries, and drug-related toxicity, posing challenges for both basic research and clinical applications. Traditional cellular and animal models, while widely used, have significant limitations in replicating the liver's complex responses to various stressors. Liver organoids derived from human pluripotent stem cells, adult stem cells primary cells, or tissues can mimic diverse liver cell types, major physiological functions, and architectural features.

Introduction: Effects of Dapagliflozin (Dapa) and Dapagliflozin-Saxagliptin combination (Combo) was examined on peripheral blood derived CD34 + Hematopoetic Stem Cells (HSCs) as a cellular CVD biomarker. Both Dapa (a sodium-glucose co-transporter 2 or SGLT2, receptor inhibitor) and Saxagliptin (a Di-peptydl-peptidase-4 or DPP4 enzyme inhibitor) are commonly used type 2 diabetes mellitus or T2DM medications, however the benefit of using the combination has not been evaluated for cardio-renal risk assessment, in a real-life practice setting, compared to a placebo.

Hypothesis: We hypothesized that Dapa will improve the outcomes when compared to placebo and the Combo maybe even more beneficial.

Semaphorin-4D signaling in recruiting dental stem cells for vascular stabilization.

Stem Cell Res Ther

January 2025

Applied Oral Sciences and Community Dental Care, Faculty of Dentistry, Prince Philip Dental Hospital, The University of Hong Kong, 34 Hospital Road, Sai Ying Pun, Hong Kong, Hong Kong SAR.

Background: Achieving a stable vasculature is crucial for tissue regeneration. Endothelial cells initiate vascular morphogenesis, followed by mural cells that stabilize new vessels. This study investigated the in vivo effects of Sema4D-Plexin-B1 signaling on stem cells from human exfoliated deciduous teeth (SHED)-supported angiogenesis, focusing on its mechanism in PDGF-BB secretion.

Background: Even though major improvements have been made in the treatment of myeloma, the majority of patients eventually relapse or progress. Patients with multiple myeloma who relapse after initial high-dose chemotherapy with autologous stem cells have a median progression free survival up to 2-3 years, depending on risk factors such as previous remission duration. In recent years, growing evidence has suggested that allogeneic stem cell transplantation could be a promising treatment option for patients with relapsed or progressed multiple myeloma.
