Recent Advances and Challenges for Biological Materials in Micro/Nanocarrier Synthesis for Bone Infection and Tissue Engineering

ACS Biomaterials Science & Engineering, Год журнала: 2025, Номер unknown

Опубликована: Март 11, 2025

Roughly 1.71 billion people worldwide suffer from large bone abnormalities, which are the primary cause of disability. Traditional grafting procedures have several drawbacks that impair their therapeutic efficacy and restrict use in clinical settings. A great deal work has been done to create fresh, more potent strategies. Under these circumstances, a crucial technique for regeneration major lesions emerged: tissue engineering (BTE). BTE involves biomaterials can imitate natural design bone. To yet, no biological material able fully meet parameters perfect implantable material, even though varieties created investigated regeneration. Against this backdrop, researchers focused interest over past few years on subject nanotechnology nanostructures regenerative medicine. The ability nanoengineered particles overcome current constraints strategies─such as decreased cell proliferation differentiation, insufficient mechanical strength materials, production extrinsic factors required effective osteogenesis revolutionized field engineering. effects nanoparticles characteristics application materials main topics our review, summarizes most recent vitro vivo research context BTE.

Transcriptomic Profile of Human Osteoblast-like Cells Grown on Trabecular Titanium

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(8), С. 3598 - 3598

Опубликована: Апрель 11, 2025

Trabecular titanium implants are widely used in orthopedic surgery and known to promote osseointegration. In this study, we investigated whether primary human osteoblast-like cells grown inside a 3D trabecular scaffold undergo changes migration capacity, transcriptomic profile, cellular phenotype as compared the same osteoblasts not scaffold. Scratch tests have shown that of from external environment into Next generation sequencing analysis demonstrated modified expression genes involved cell cycle extracellular matrix remodeling, while maintaining normal specific osteoblast markers, such osteocalcin osterix, well comparable mineralization capacity. These data demonstrate acquire features favoring

Mechanical Properties and Decomposition Behavior of Compression Moldable Poly(Malic Acid)/α-Tricalcium Phosphate Hybrid Materials

Polymers, Год журнала: 2025, Номер 17(2), С. 147 - 147

Опубликована: Янв. 9, 2025

Calcified tissues in living organisms, such as bone, dentin, and enamel, often require surgical intervention for treatment. However, advances regenerative medicine have increased the demand materials to assist regenerating these tissues. Among various forms of calcium phosphate (CaP), tricalcium (TCP)-particularly its α-TCP form-stands out due high solubility efficient release, making it a promising candidate bone regeneration applications. Nevertheless, rapid dissolution rate presents challenges when used reinforcing agent. In this study, we developed hybrid material composed poly(malic acid) (PMA) achieve controlled release while maintaining mechanical strength. The were prepared using compression molding method optimized suppress hydrolysis PMA. bond between carboxyl group PMA was confirmed through infrared (IR) spectroscopy. A test demonstrated that interaction extends period both components. These findings indicate PMA/α-TCP significant potential applications tissue engineering.

Fabrication and Characterization of 3D-Printed Porous Structures Based on Walstromite-Type Silicate Ceramics

Inorganics, Год журнала: 2025, Номер 13(3), С. 68 - 68

Опубликована: Фев. 25, 2025

This study investigates the additive manufacturing of 3D porous scaffolds based on walstromite-type silicate ceramics for bone tissue engineering applications. Walstromite powders were synthesized using sol-gel method and printed extrusion-based printing. Both sintered unsintered characterized scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD) energy dispersive X-ray (EDS) analyses to evaluate effects sintering microstructure, porosity, mechanical properties. Results indicate that exhibited significantly higher compressive strength due presence organic binders, whereas demonstrated enhanced facilitating cell infiltration nutrient flow. Therefore, process reduced strength, probably loss compounds increased porosity. These findings underline need optimizing parameters balance integrity ensuring meet biological requirements regeneration. Alternative methods, such as microwave sintering, are also suggested future research minimize degradation observed post-sintering.
