Summary: The study demonstrates a method to enhance the osteogenic potential of MSCs by modulating the expression levels of specific genes. It was found that using Locked Nucleic Acid-Antisense Oligonucleotides and a scaffold releasing low doses of BMP-2 can increase the osteogenic potential of MSCs. By specifically targeting the Wnt pathway modulator Sfrp1, the efficiency of MSC bone regeneration can be improved and osteogenic differentiation in osteoporotic patients' MSCs can be induced.

Summary: The development of scaffolds combining BMP-2 and MMP-10 shows promise for osteoporosis management, with a positive effect on tissue repair for OP mice but a potentially detrimental effect on non-OP animals. Therapeutic molecules can be efficiently encapsulated and controlled released, showing benefits on non-OP cells and similar effects on OP cells.

Summary: Recent studies have shown that MSCs play a vital role in bone regeneration, including osteogenic differentiation and providing seed cells. However, factors like drug intake and body senescence can affect MSCs' functions in bone regeneration. Epigenetic regulation has received attention for its heritable nature and involvement in bone metabolism disorders. This review focuses on the effects of epigenetic regulation on osteogenic differentiation, proliferation, and cellular senescence in MSCs and its role in bone regeneration.

Summary: Nowadays, there is growing interest in developing systems that can guide and influence cell activities for bone regeneration. In this study, researchers combined type-I collagen and superparamagnetic iron oxide nanoparticles (SPIONs) to design magnetic and biocompatible electrospun scaffolds for bone regeneration. The experimental results showed that the nanostructured scaffolds composed of collagen fibers with embedded SPIONs exhibited enhanced magnetic properties and preserved the viability and adhesion of bone cells.

Summary: Periodontitis is a common chronic inflammatory disease that damages the tissues supporting the teeth. It has three distinct stages: infection, inflammation, and tissue destruction, each requiring specific treatment. Understanding the underlying mechanisms of alveolar bone loss is crucial for effective periodontitis treatment and subsequent reconstruction of the periodontium.

Summary: Bone formation is a complex regeneration process regulated by multiple signaling pathways, with the Hedgehog (Hh) pathway playing a crucial role. Dysregulation of the Hh pathway in adults is associated with bone-related diseases, while during repair processes, it can be reactivated to modulate bone formation. Current therapeutic strategies targeting the Hh cascade for osteogenesis coordination have been reviewed.

Summary: This study evaluated the osteogenic activity of dual drugs (Dex and BMP-2) loaded into a gelatin scaffold in vivo, and investigated the mechanism of osteogenesis induced by these drugs using C2C12 cells. Results showed that the gelatin scaffold with Dex and BMP-2 significantly accelerated osteogenesis in vivo, and Dex enhanced the osteogenic effect of BMP-2 through activation of the Runx2 pathway.

Summary: In this study, a new osteoconductive scaffold was developed, which reduced the required doses of BMP-2 for bone regeneration. The scaffold showed promising results in promoting cell adhesion, proliferation, and osteogenic differentiation of human bone-marrow derived mesenchymal stem cells (hBM-MSCs). The sustained release of BMP-2 from the scaffold allowed for the treatment of critical-sized osteoporotic bone defects with relatively low growth factor doses.

Summary: This study investigated the cytotoxicity of oxazine 4-perchlorate (O4P) on U87 glioma cells at different concentrations and operating room irradiation modes. DNA damage and intracellular localization of O4P were also studied using immunofluorescence and confocal microscopy. The results suggest that concentrations below 100 μM can be considered safe, contributing to the evaluation of O4P as a nerve biomarker.

Summary: Norzoanthamine (NZ), an alkaloid isolated from marine cnidiaria Zoanthus sp., has shown interesting anti-osteoporotic activity. This in vivo study demonstrates that direct application of NZ into ovariectomized rat bone results in higher bone quality and balanced osteoblast/osteoclast ratio, similar to normal bone. NZ could be a useful adjunct to existing osteoporosis treatments or as a preventive therapy against bone deterioration.

Summary: In this study, we compared the synthesis of polyethyleneimine (PEI) nanoparticles using different methods and found that coaxial electrospraying is a promising technique for the production of therapeutic nanoparticle-based carriers. The nanoparticles synthesized by coaxial electrospraying showed efficient RNA-based drug encapsulation, increased nanoparticle surface availability for functionalization, high transfection efficiency, and hyperactivation of clathrin-independent endocytic pathways as the main intracellular uptake mechanism.

Summary: This study found that leiomyoma cells can repopulate cell-depleted tissue slices in organ culture, and clusters of CD49b(+) cells were observed in tumor slices. In contrast, CD49b(+) cells were sparsely detected in myometrial slices. Furthermore, leiomyoma cells strongly expressed Ki67 while myometrial cells only had a few stained cells. Based on these findings, it is proposed that activating CD49b(+) stem cells in the myometrium leads to asymmetrical division, giving rise to transit-amplifying KIT+ cells that differentiate to smooth muscle cells. On the other hand, activated leiomyoma CD49b(+) cells symmetrically divide to form clusters of stem cells that divide and differentiate to smooth muscle cells without losing proliferation ability.
