Successful outcomes of cell-based therapeutic is highly-dependent on quality and quantity of the cells. Epigenetic modifiers are known to modulate cell fates via reprogramming, hence it is plausible to use them in enhancing the plasticity of mesenchymal stem cells. In this study, we aimed to study the effects of 5-Azacytidine (5-AzaCR), an epigenetic modifier, pretreatment on mesenchymal stem cells-derived from Wharton's Jelly (WJMSCs) fates. WJMSCs were pretreated with 5-AzaCR for 24 h and subsequently cultured in culture media mixtures. The proliferative and stemness characteristics of the pretreated WJMSCs were assessed through morphological and gene expression analyses. Results showed that cells pretreated with 5 μM to 20 μM of 5-AzaCR showed to acquire higher proliferative state transiently when cultured in embryonic-mesenchymal stem cell (ESC-MSC) media, but not in MSC medium alone, and this coincides with significant transitional upregulation of stemness transcription factors. 5-AzaCR pretreatment has potential to confer initial induction of higher state of stemness and proliferation in WJMSCs, influenced by the culture media.

Background: Pathogenic or null mutations in WRN helicase is a cause of premature aging disease Werner syndrome (WS). WRN is known to protect somatic cells including adult stem cells from premature senescence. Loss of WRN in mesenchymal stem cells (MSCs) not only drives the cells to premature senescence but also significantly impairs the function of the stem cells in tissue repair or regeneration.

Introduction: Periodontal diseases are prevalent among middle-aged and elderly individuals. There's still no satisfactory solution for tooth loss caused by periodontal diseases. Human periodontal ligament stem cells (hPDLSCs) is a distinctive subgroup of mesenchymal stem cells, which play a crucial role in periodontal supportive tissues, but their application value hasn't been fully explored yet.

Epiregulin plays a role in a range of biological activities including malignancies. This study aims to investigate the potential contribution of epiregulin to bone cell differentiation and bone homeostasis. The data showed that epiregulin expression was upregulated during osteogenesis but downregulated during adipogenesis.

Phytochemicals, which are bioactive compounds contained in fruits, vegetables, and teas, have a positive effect on human health by having anti-inflammatory, antioxidant, and anticarcinogenic effects. Several studies have highlighted the ability of bioactive compounds to activate key cellular enzymes associated with important signaling pathways related to cell division and proliferation, as well as their role in inflammatory and immunological responses. Some phytochemicals are associated with increased proliferation, differentiation, and expression of markers related to osteogenesis, bone formation, and mineralization by activating various signaling pathways.

As a promising candidate for tackling drug-resistant cancers, triptolide, a diterpenoid derived from the Chinese medicinal plant Tripterygium wilfordii, has been developed. This review summarizes potential antitumor activities, including the suppression of RNA polymerase II, the suppression of heat shock proteins (HSP70 and HSP90), and the blockade of NF-kB signalling. Triptolide is the first known compound to target cancer cells specifically but spare normal cells, and it has success in treating cancers that are difficult to treat, including pancreatic, breast, and lung cancers.
