Nitrogen-containing bisphosphonate induces enhancement of OPG expression and inhibition of RANKL expression via inhibition of farnesyl pyrophosphate synthase to inhibit the osteogenic differentiation and calcification in vascular smooth muscle cells

BMC Cardiovascular Disorders
Background Nitrogen-containing bisphosphonate(N-BP)had been found to inhibit the osteogenic differentiation and calcification in vascular smooth muscle cells (VSMCs), but the mechanism is not clear.

Sirt3 Genetically Engineered Apoptotic Bodies Alleviate Skeletal Aging by Limiting Aggravated NLRP3 Inflammasome Activation of Senescent Macrophages

Advanced Science, EarlyView.
The senescence of macrophages leads to a decrease in the expression of Sirtuin3 (Sirt3), which in turn aggravates the NLRP3 inflammasome activation and IL‐1β secretion, thereby promoting the aging‐related osteoporosis. Sirt3‐enriched apoptotic bodies (ABs‐Sirt3) generated through genetic editing approaches can alleviate skeletal aging by targeting ...

EIF4A3 enhances the viability, invasion and osteogenic differentiation of BMSCs via the USP53/SMAD5 pathway

Scientific Reports
SMAD5 has been demonstrated to promote osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) through the circ_0001825/miR-1270/SMAD5 axis or KCNQ1OT1/miR-320a/SMAD5 axis.

Distinct Immunomodulatory Strategies Guide Mesenchymal Stromal/Stem Cell‐Mediated Bone Regeneration

Advanced Science, EarlyView.
Bone regeneration by mesenchymal stem cells is strongly influenced by immune signals. This study shows that priming stem cells with regulatory immune cells or an inflammation‐resolving lipid molecule enhances bone formation through distinct immune pathways.

A BioLiving Periosteum Evokes Centripetal Regeneration in Challenging Bone Defects

Advanced Science, EarlyView.
Large bone defects often suffer from insufficient central healing. This study engineers a BioLiving periosteum that mimics the native structure. It sequentially delivers remote chemical cues and contact physical cues in a signaling‐relay manner, effectively recruiting and guiding endogenous cells toward the defect center.

Polymer Matrix‐Based 3D Culture Significantly Enhances the Differentiation and Immunomodulatory Functions of Human Adipose‐Derived Stem Cells

Advanced Science, EarlyView.
The 3D culture of human adipose‐derived stem cells (hADSCs) on a crosslinked cyclosiloxane‐based poly‐Z matrix platform enables the formation of spheroid structures enriched with extracellular matrix (ECM). These ECM‐enriched hADSC spheroids cultured on poly‐Z exhibit enhanced differentiation potential, immunomodulatory capacity, and in vivo ...

USP2-induced upregulation of LEF1 through deubiquitination relieves osteoporosis development by promoting the osteogenic differentiation of bone marrow mesenchymal stem cells

Journal of Orthopaedic Surgery and Research
Background Bone marrow mesenchymal stem cells (BMSCs) exhibit therapeutic potential for osteoporosis through their differentiation into osteoblasts. Here, we investigated the role and mechanism of lymphoid enhancer-binding factor 1 (LEF1) in regulating ...

Development of an early estimation method for predicting later osteogenic differentiation activity of rat mesenchymal stromal cells from their attachment areas

Science and Technology of Advanced Materials, 2012
Cell morphology has received considerable attention in recent years owing to its possible relationship with cell functions, including proliferation, differentiation, and migration. Recent evidence suggests that extracellular environments can also mediate
