Article Abstract
Stem cell-based bone tissue engineering offers a promising approach for treating oral and cranio-maxillofacial bone defects. This study investigated the role of Atoh8, a key regulator in various cells, in the osteogenic potential of adipose-derived stem cells (ADSCs). ADSCs transfected with small interfering RNA (siRNA) targeting Atoh8 were evaluated for proliferation, migration, adhesion, and osteogenic capacity. In vivo, 20 SD rats were used to assess bone regeneration using Atoh8-knockdown ADSC sheets, with new bone formation quantified via micro-CT and histological analysis. Atoh8 knockdown in vitro reduced ADSC proliferation and migration but enhanced osteogenic differentiation and upregulation of osteogenic-related factors. This approach improved bone healing in rat defect models, accelerating repair both in vitro and in vivo. The findings underscore the clinical potential of ADSCs in bone tissue engineering and elucidate Atoh8's regulatory role in ADSC osteogenesis, providing a novel therapeutic strategy for enhancing bone regeneration through targeted modulation of stem cell differentiation pathways.

Adipose-derived mesenchymal stem cells (ADSCs) hold great promise for bone tissue repair and regeneration. Circular RNAs (circRNAs) play a crucial role in regulating the osteogenic differentiation and bone remodeling of ADSCs; however, the underlying molecular mechanisms remain unclear. In this study, we conducted whole transcriptome sequencing (WTS) on ADSCs and constructed a competing endogenous RNA (ceRNA) regulatory network to identify the circTTC3/miR-205/mothers against decapentaplegic homolog 3 (Smad3) signaling axis.

Background: Critical size bone defects represent a clinical challenge, associated with considerable morbidity, and frequently trigger the requirement of secondary procedure. To fill osseous gaps, multiple steps are required, such as proliferation and differentiation on the cellular level and the building of extracellular matrix. In addition, the osteogenic potential of cell-derived extracellular matrices (CD-ECM) is known to enhance bone healing.

Maxillary underdevelopment is a critical component of skeletal Class III malocclusion, closely linked to altered biomechanical signaling. Mechanical stimulation through early facemask protraction can effectively promote maxillary growth, yet the underlying mechanotransduction mechanisms remain unclear. In this study, fibroblast growth factor 9 (FGF9) is identified as a key biomechanical responder in maxillary development.

The important role of the EphrinB2-EphB4 signalling pathway in bone remodelling has been demonstrated, while its effect on inflammatory bone defect regeneration remains poorly understood. This study was to assess the effect of EphB4-EphrinB2 signalling on inflammation-mediated bone defect repair in murine models. The modelling method of inflammation-mediated bone defect in mice was established by intraperitoneally injecting different concentrations of TNF-α.

Natural protein-derived peptides are gaining attention for their potential in promoting health, particularly in nutraceutical formulations. In this study, calcium-binding peptides from lotus seed were produced and characterized using UV, FT-IR, Raman, and EDS, and SEM. The calcium-peptide (LSPIH-Ca) complex was subjected to its osteogenic effect in murine bone marrow-derived mesenchymal stem cells (D1 MSCs).
