Objective: Sertoli cells (SCs) are a major component of testis which secrete a variety of cytokines and immunosuppressive factors, providing nutritional support and immune protection for sperm growth and development. The purpose of this study was to investigate the relationship between SCs and bone marrow mesenchymal stem cells (BMSCs) in order to provide a theoretical basis for better application of SCs.
Methods: We used the adherence method to isolate Sprague-Dawley rat SCs and BMSCs. Cells surface markers were detected by flow cytometry. The capacity of cells to differentiate was determined by osteogenic and adipogenic induction. Assessment of cell proliferation was performed by MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2-H-tetrazolium bromide] assay. Changes in the nucleus were analyzed by Hoechst nuclear staining. Cell aging was observed with β-galactosidase, which is a biological marker of senescence. RT-PCR was employed to detect the expression of cytokines.
Results: From the aforementioned experiments, we found that the surface markers of SCs and BMSCs were almost exactly the same. Proliferation of SCs, as well as osteogenic and adipogenic differentiation, were weaker than in BMSCs. Compared with BMSCs, Hoechst nuclear staining showed that the chromatin of SCs began to aggregate and was slightly larger. β-galactosidase staining showed that SCs were in a slightly aging state. The secretion of cytokines from SCs was slightly less than the secretion from BMSCs.
Conclusion: SCs are a kind of mesenchymal stem cells which have begun the process of differentiation.

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.
