Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

Advanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

miR-539 mediates osteoblast mineralization by regulating Distal-less genes 2 in MC3T3-E1 cell line

Open Life Sciences, 2017
microRNAs (miRNAs) play an important role in osteoblast differentiation. However, the mechanisms of miRNAs regulating osteoblast mineralization still needs to be further cleared.

The effect of application of bovine amniotic membrane on osteoblasts, osteocytes, and collagen in the post-extraction alveolar bone socket of Sprague Dawley rats

Padjadjaran Journal of Dentistry, 2023
Introduction: Tooth extraction can result in loss of alveolar bone. The application of biomaterials Bovine Amniotic Membrane (BAM) that containing growth factors and collagen is expected to play a role in socket preservation.

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Inhibition of Osteoblast Function by Brucella abortus is Reversed by Dehydroepiandrosterone and Involves ERK1/2 and Estrogen Receptor

Frontiers in Immunology, 2018
Brucella abortus induces an inflammatory response that stimulates the endocrine system resulting in the secretion of cortisol and dehydroepiandrosterone (DHEA).

Cytotoxicity Effects of Polyhydroxybutyrate/Chitosan/Bioglass Nanocomposite Scaffolds on Human Osteoblast-like Cells (SAOS-2 Cells)

مجله دانشکده دندانپزشکی اصفهان, 2022
In tissue engineering, a porous material is applied as the extracellular matrix or scaffold for cell growth. Then growth factors are added to this scaffold whose cytotoxicity must be assessed.

Osteoblast biology: developmental origin and interactive nature of osteoblasts

, 2021
Bone formation occurs throughout life to support growth and bone remodeling in response to mechanical forces, metabolic needs, and tissue repair upon injury. The physiological requirement for continuous bone renewal to accommodate remodeling necessitates recruitment, proliferation, and differentiation of bone-forming osteoblasts to counteract the ...

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

Advanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Eucommia ulmoides Oliver polysaccharide alleviates glucocorticoid-induced osteoporosis by stimulating bone formation via ERK/BMP-2/SMAD signaling

Scientific Reports
Osteoporosis (OP) is a metabolic disease characterized by low bone mineral mass owing to osteoblast dysfunction. Eucommia ulmoides Oliver (EuO) is a Chinese herbal medicine traditionally used to treat OP.
