The ubiquitin-proteasome system is an important pathway for mediating posttranslational modification and protein homeostasis and exerts a wide range of functions in diverse biological processes, including stem cell differentiation, DNA repair, and cell cycle regulation. Many studies have shown that ubiquitination modification plays a critical role in regulating the osteogenic differentiation of stem cells and bone formation through various mechanisms. This review summarizes current progress on the effects and mechanisms of ubiquitin modification on transcription factors and signaling pathways involved in osteogenic differentiation. Moreover, the review highlights the latest advances in the clinical application of drugs in bone tissue engineering. A thorough understanding of ubiquitin modifications may provide promising therapeutic targets for stem cell-based bone tissue engineering.

Immune cells, such as macrophages, stimulated by several types of inorganic ions released from bioactive glasses secrete cytokines that promote and inhibit bone formation. In this study, the effects of borate-ion-stimulated mouse macrophages (RAW264) on the osteogenic differentiation of mouse bone marrow-derived mesenchymal stem cells (KUSA-A1) are investigated. KUSA-A1 is cultured with a borate-ion-containing medium and RAW264-conditioned medium, which contained the secretome released from boron-stimulated RAW264, and its osteogenic differentiation is evaluated.

Background: Guided bone regeneration (GBR) relies on biocompatible membranes to support osteogenesis. 1,4-butanediol diglycidyl ether (BDDE)-crosslinked hyaluronic acid (xHyA) has shown promise in enhancing bone regeneration, yet its mechanisms remain unclear.
Objective: This study evaluates the osteogenic effects of xHyA-functionalized native pericardium collagen membrane (NPCM) and ribose-crosslinked collagen membrane (RCCM) using an airlift culture model with SaOS-2 cells.

Although platelet-rich plasma (PRP) has demonstrated considerable regenerative potential in regenerative endodontic treatment, its clinical efficacy may be limited by the rapid degradation of its bioactive components, leading to inconsistent outcomes. To overcome this challenge, the present study explores the use of nano-sized exosomes derived from PRP-a novel designated as PRP exosomes (PRP-Exo)-as a more stable and targeted biomolecular delivery system to promote odontogenic differentiation within the dentin-pulp complex. The primary objective is to investigate the expression of key odontogenic markers, transforming growth factor-β1 (TGF-β1) and Dentin Sialophosphoprotein (DSPP), in human dental pulp stem cells (hDPSCs) following PRP-Exo treatment.

Enoxaparin sodium (ES), a low molecular weight heparin derivative, has recently been recognized for its diverse biological activities. In particular, the ability of heparin to modulate inflammation has been utilized to enhance the biocompatibility of bone implant materials. In this study, we utilized poly (methyl methacrylate) (PMMA), a drug loading bone implant material, as a matrix and combined this with enoxaparin sodium (ES) to create enoxaparin sodium PMMA cement (ES-PMMA) to investigate the regulatory effects of ES on inflammatory responses in bone tissue from an animal model.
