Tissue inhibitor of metalloproteinase-1 (TIMP-1) regulates mesenchymal stem cells through let-7f microRNA and Wnt/β-catenin signaling [PDF]

, 2012
Tissue inhibitor of metalloproteinases 1 (TIMP-1) is a matrix metalloproteinase (MMP)-independent regulator of growth and apoptosis in various cell types.

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Oncostatin M promotes osteogenic differentiation of tendon-derived stem cells through the JAK2/STAT3 signalling pathway

Journal of Orthopaedic Surgery and Research
Purpose Oncostatin M (OSM) is involved in the regulation of osteogenic differentiation and has a major role in the development of heterotopic ossification.

Comparative study of osteogenic activity of multilayers made of synthetic and biogenic polyelectrolytes [PDF]

, 2017
Polyelectrolyte multilayer (PEM) coatings on biomaterials are applied to tailor adhesion, growth, and function of cells on biomedical implants. Here, biogenic and synthetic polyelectrolytes (PEL) are used for layer-by-layer assembly to study the ...

3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

Advanced Functional Materials, EarlyView.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

Multi-omics of in vitro aortic valve calcification

Frontiers in Cardiovascular Medicine, 2022
Heart valve calcification is an active cellular and molecular process that partly remains unknown. Osteogenic differentiation of valve interstitial cells (VIC) is a central mechanism in calcific aortic valve disease (CAVD).

Local origins impart conserved bone type-related differences in human osteoblast behaviour [PDF]

, 2015
Osteogenic behaviour of osteoblasts from trabecular, cortical and subchondral bone were examined to determine any bone type-selective differences in samples from both osteoarthritic (OA) and osteoporotic (OP) patients.

Self‐Assembled Nanoclay Gel With Spheroid MSC‐Derived Exosome Mimetics to Integrate Demineralized Bone Matrix and Noggin‐Targeting miRNA for Synergistic Osteogenesis

Advanced Functional Materials, EarlyView.
We report a versatile nanoclay gel carrier platform that enhances the osteogenic efficacy of demineralized bone matrix (DBM) by integrating nanoclay‐based self‐assembly with cell‐derived exosome mimetics loaded with noggin‐targeting miR‐200c. This design amplifies BMP signaling, thereby promoting DBM‐mediated osteogenesis and offering a promising ...

Long noncoding RNA KCNMA1-AS1 promotes osteogenic differentiation of human bone marrow mesenchymal stem cells by activating the SMAD9 signaling pathway

Biology Direct, 2023
The human bone marrow mesenchymal stem cells (hBMSCs) undergo intense osteogenic differentiation, a crucial bone formation mechanism. Evidence from prior studies suggested an association between long noncoding RNAs (lncRNAs) and the osteogenic ...

Dnmt3b ablation impairs fracture repair through upregulation of Notch pathway [PDF]

, 2020
We previously established that DNA methyltransferase 3b (Dnmt3b) is the sole Dnmt responsive to fracture repair and that Dnmt3b expression is induced in progenitor cells during fracture repair.
