Biofabrication of Sodium Alginate Hydrogel Scaffolds for Heart Valve Tissue Engineering

Yannick Rioux et al.

Summary: This article presents a novel technique for rapid fabrication of native-like tricuspid aortic valve scaffolds using an alginate-based hydrogel. The technique involves injecting a sodium alginate hydrogel formulation into a mold produced using a custom-made sugar glass 3D printer, and dissolving the mold using a custom-made dissolving module. The results of CT scans and tests in a cardiac bioreactor demonstrate the functional repeatability of this new biofabrication method, suggesting its potential for rapid fabrication of cell-seeded sodium alginate scaffolds for heart valve tissue engineering.

Powder 3D Printing of Bone Scaffolds with Uniform and Gradient Pore Sizes Using Cuttlebone-Derived Calcium Phosphate and Glass-Ceramic

Francesca Cestari et al.

Summary: The pore geometry of bone scaffolds has a significant impact on cellular response. 3D printing technology allows for the full control and design of porosity in bone tissue engineering. Recently, natural calcium phosphate materials have gained attention for their similarity to natural bone and superior bioactivity. However, their nanometric size makes them challenging to process using 3D printing. This study fabricated bone scaffolds with different pore geometries using a biphasic calcium phosphate nanopowder derived from cuttlebones. The addition of bio-derived powder increased the porosity of the scaffolds, indicating that nanoparticles slowed down the glass-ceramic densification. The cellular behavior on the scaffolds with gradient pores and cuttlebone-derived powder showed a decrease in metabolic activity over time, potentially indicating cell differentiation.

Effects of Fumed Silica on Thixotropic Behavior and Processing Window by UV-Assisted Direct Ink Writing

Fengze Jiang et al.

Summary: This research discussed the effects of fumed silica on the rheological behavior and processing windows of UV ink. It was found that a suitable amount of fumed silica can improve the printing speed and accuracy by enhancing the ink's rheological behavior and expanding the processing window. However, an excessively high concentration of fumed silica will increase the ink's viscosity and the requirements for equipment.

In Vivo Analysis of the Regeneration Capacity and Immune Response to Xenogeneic and Synthetic Bone Substitute Materials

James Bielenstein et al.

Summary: This study analyzes the in vivo responses to xenogeneic and synthetic bone substitute granules, revealing differences in bone regeneration and immune response. The synthetic BSM induces a higher pro-inflammatory response, while the xenogeneic BSM induces a higher anti-inflammatory reaction. However, both materials show comparable bone regeneration. The results demonstrate the biocompatibility of the synthetic BSM maxresorb (R) and suggest it as a suitable alternative to natural BSM for various indications.

Production of Mesoglycan/PCL Based Composites through Supercritical Impregnation

Sara Liparoti et al.

Summary: The development of targeted therapies for wound repair is gaining interest due to the aging population and the rise of chronic illnesses like pressure ulcers. Sodium mesoglycan (MSG) has been proven effective in wound healing and in this study, attempts were made to impregnate MSG into polymer matrices using a supercritical carbon dioxide-based process. Two techniques, compression molding and electrospinning, were used to obtain different film structures. The choice of water-soluble polymer influenced the rate of drug release.

3D Printing of Cellulase-Laden Cellulose Nanofiber/Chitosan Hydrogel Composites: Towards Tissue Engineering Functional Biomaterials with Enzyme-Mediated Biodegradation

Arnaud Kamdem Tamo et al.

Summary: This study proposes a 3D printing method for a multifunctional hydrogel biomaterial with bioactivity, good mechanical properties, and biodegradability. The method utilizes encapsulated cellulase and cellulose nanofiber filled chitosan viscous suspensions as bioinks to 3D print enzymatic biodegradable and biocompatible cellulose nanofiber reinforced chitosan hydrogels. The incorporation of the enzyme within the hydrogel helps control the degradation of cellulose while maintaining the cell growth-promoting property of chitosan. The 3D printed composite hydrogels exhibit excellent cytocompatibility and biodegradability.

Matrix Metalloproteases from Adipose Tissue-Derived Stromal Cells Are Spatiotemporally Regulated by Hydrogel Mechanics in a 3D Microenvironment

Francisco Drusso Martinez-Garcia et al.

Summary: Adipose tissue-derived stromal cells (ASCs) are a promising research subject in tissue engineering and regenerative medicine due to their easy acquisition, multipotency, and secretion of factors promoting tissue regeneration. However, their retention in or around lesions after direct administration is poor. To address this issue, ASCs can be "immobilized" in hydrogels such as gelatine methacryloyl (GelMA). This study found that the concentration of GelMA can influence the expression of matrix metalloproteases (MMPs) secreted by ASCs, as well as their morphology and the ultrastructure of the hydrogel.
