Mineral‐targeted alkaline phosphatase improves bone graft‐mediated alveolar bone defect healing in mice

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Alveolar bone loss challenges tooth retention and implant placement. Freeze‐dried bone allograft (FDBA) is widely used for alveolar ridge preservation but has limitations in resorption rate and healing time. In this proof‐of‐concept study, we tested whether pro‐mineralization enzyme, tissue‐nonspecific alkaline phosphatase (TNAP ...

Transplantation of Hypoxic-Preconditioned Bone Mesenchymal Stem Cells Retards Intervertebral Disc Degeneration via Enhancing Implanted Cell Survival and Migration in Rats

open access: yesStem Cells International, 2018
Objective. Special hypoxic and hypertonic microenvironment in intervertebral discs (IVDs) decreases the treatment effect of cell transplantation. We investigated the hypothesis that hypoxic preconditioning (HP) could improve the therapeutic effect of ...

Nestinþ cells direct inflammatory cell migration in atherosclerosis [PDF]

open access: yes, 2016
Atherosclerosis is a leading death cause. Endothelial and smooth muscle cells participate in atherogenesis, but it is unclear whether other mesenchymal cells contribute to this process. Bone marrow (BM) nestinþ cells cooperate with endothelial cells in

Valproic Acid Inhibits Ferroptosis and Improves Bone Integration in OVX Rats Through the AMPK/SIRT1 Pathway

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prevalence of postmenopausal osteoporosis (PMOP) has been steadily increasing. Ferroptosis has been recognized as a critical factor influencing the bone‐forming ability of bone marrow mesenchymal stem cells (BMSCs). Valproic acid (VPA), an HDAC inhibitor, has been suggested to play a role in regulating osteoporosis development; however ...

Directing mesenchymal stem cells to bone to augment bone formation and increase bone mass. [PDF]

open access: yes, 2012
Aging reduces the number of mesenchymal stem cells (MSCs) that can differentiate into osteoblasts in the bone marrow, which leads to impairment of osteogenesis.

SP1 regulates BMSC osteogenic differentiation through the miR-133a-3p/MAPK3 axis

open access: yesJournal of Orthopaedic Surgery and Research
Abstract Background The progression of osteoporosis (OP) can dramatically increase the risk of fractures, which seriously disturb the life of elderly individuals. Specific protein 1 (SP1) is involved in OP progression. However, the mechanism by which SP1 regulates OP progression remains unclear.

Extracellular Vesicle‐Mediated Communication Between Anterior Cruciate Ligament and Bone Marrow Cells Modulates Hamstring Tenocyte Behavior and Apoptosis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Following anterior cruciate ligament (ACL) reconstruction, enhancing hamstring tenocyte activity and minimizing apoptosis are critical for preventing graft failure and promoting ligamentization. This study investigated the therapeutic potential of extracellular vesicles (EVs) derived from a coculture of ACL remnant cells and bone marrow ...

Biodegradable Natural Polymer‐Based Drug Delivery Systems for Bone Tissue Engineering

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT The increasing incidence of bone diseases and injuries, especially among aging populations, has underscored the shortcomings of traditional treatments such as bone grafts and metal implants, which often face complications including immune rejection, mechanical failure, and delayed healing.

Curcumin Alleviates the Osteogenesis Inhibition and the Aging Process in BMSCs Induced by Iron Overload Through Activating the NRF2/GPX4 Pathway

open access: yesPhytotherapy Research, EarlyView.
Under iron overload conditions, curcumin inhibits cellular senescence and promotes osteogenic differentiation by activating the NRF2/GPX4 signaling pathway in bone marrow mesenchymal stem cells (BMSCs), thereby preventing the onset of osteoporosis. ABSTRACT Dysregulated proliferation and differentiation of bone marrow mesenchymal stem cells (BMSCs ...

Harnessing energy metabolism for enhanced bone defect repair: Mechanisms and therapeutic strategies

open access: yesVIEW, EarlyView.
This review addresses the critical challenge of bone defect repair by focusing on the underexplored role of cellular energy metabolism. It synthesizes regulatory mechanisms in bone‐forming cells and sums up innovative strategies—leveraging cell derivatives, active factors, and biomimetic scaffolds—to modulate metabolism for enhanced regeneration.
