Summary: Haematopoietic ageing is characterized by a loss of regenerative capacity and abnormal differentiation of haematopoietic stem cells (HSCs), resulting in impaired blood production. The study reveals an inflammatory environment in the old bone marrow niche, which contributes to niche deterioration, HSC dysfunction, and impaired haematopoietic regeneration. The production of interleukin-1 beta (IL-1 beta) by damaged endosteum drives the proinflammatory nature of the central marrow, causing damage to the old blood system. Blocking IL-1 signaling is a potential strategy to improve blood production during ageing.

Summary: The loss of NFIX gene affects endochondral ossification and mineralization in bone, with NFIX inducing osteoblast differentiation and impairing adipocyte formation by regulating HMGA1 expression. HMGA1 plays a role in osteoblast commitment and mediates NFIX function by activating canonical Wnt signaling pathways.

Summary: In this study, TNS3 was found to be involved in the fate decision of human bone marrow-derived stromal cells (BMSCs), regulating osteogenesis and adipogenesis through the control of RhoA activity and cytoskeletal reorganization. The findings highlight the crucial role of TNS3 in bone metabolism.

Summary: This study investigated the impact of cell culture density on stem cell proliferation, osteoblastogenesis, and regulation. The results showed that the proliferation rate of human periodontal ligament stem cells (hPDLSCs) decreased with an increase in initial plating density. After osteogenic differentiation, hPDLSCs initially plated at a density of 2 x 10(4) cells/cm(2) showed the highest expression of OPG and RUNX2, as well as the highest OPG/RANKL ratio and cell calcium concentration. Furthermore, exosomes derived from hPDLSCs cultured at different initial cell densities were found to regulate osteoblastic differentiation of human bone marrow stromal cells (hBMSC), with the 2 x 10(4) cells/cm(2) initial cell density group showing the highest expression of OPG, OCN, RUNX2, and osterix, as well as the highest average calcium concentration. This provides a new perspective for the clinical application of stem cell osteogenesis.

Summary: This study investigated the effects of scoparone (SCOP), derived from Artemisia capillaris Thunb, on osteogenic processes using MC3T3-E1 pre-osteoblasts. SCOP showed no cytotoxic effects and promoted alkaline phosphatase staining, mineralized nodule formation, and osteogenic signals. SCOP also induced autophagy, migration, and adhesion. Overall, SCOP has osteogenic effects associated with cell differentiation, adhesion, migration, autophagy, and mineralization.

Summary: This study investigated the effects of a flavonoid called trifolirhizin (trifol) derived from Sophora flavescens on osteogenic processes during osteoblast differentiation. It was found that trifol promoted osteoblast differentiation markers and stimulated major osteogenic signaling proteins. Trifol also increased osteoblast-mediated bone-forming phenotypes. These findings suggest that trifol may be an effective phytomedicine for bone diseases such as osteoporosis.

Summary: Our study demonstrated that TGF-beta signaling inhibits osteogenic differentiation in ASC, DSC, and FB during early cell culture passages. DSC showed the best osteogenic differentiation potential, which could be further enhanced with BMP-2 activation of BMP signaling. Cell-based therapies should consider the functional differences in osteogenic differentiation of ASC, DSC, and FB based on their tissue origin and replicative senescence.

Summary: This study aimed to explore the role of miR-129-5p in regulating bone marrow mesenchymal stem cell (BMSC) differentiation and bone regeneration. The results showed that miR-129-5p promotes osteogenic differentiation of BMSCs and bone regeneration, and the miR-129-5p/Dkk3 axis may be new potential targets for the treatment of bone defect and bone loss.

Summary: In this study, 1Azakenpaullone was identified as a highly selective inhibitor that induced osteoblastic differentiation and mineralization of human mesenchymal stem cells (MSCs) by activating the Wnt signaling pathway and nuclear accumulation of beta-catenin, leading to the upregulation of Runx2 and the expression of osteoblast-specific genes. Therefore, 1Azakenpaullone could be used as an osteo-promoting factor in bone tissue engineering.

Summary: Arboviruses like Zika virus affect bone development by targeting osteoblasts and altering bone remodeling. In this study, the researchers investigated the effects of Zika virus infection on mesenchymal stromal cells (MSCs) at different stages of osteogenesis. They found that late-stage infected MSCs showed elevated osteogenic markers, calcium content, and altered gene expression compared to early-stage infected MSCs.

Summary: Tax1bp3 is a PDZ domain-containing protein that is overexpressed in cancer and can regulate the differentiation of mesenchymal progenitor cells into osteoblasts and adipocytes. It inhibits osteogenic differentiation and promotes adipogenic differentiation by inhibiting the activation of Wnt/beta-catenin and BMPs/Smads signaling pathways.
