Bioprinted Cancer Model of Neuroblastoma in a Renal Microenvironment as an Efficiently Applicable Drug Testing Platform

Dongwei Wu et al.

Summary: This study developed a neuroblastoma three-dimensional model based on a human-derived environment, which can be used to test the cytotoxicity and tumor selectivity of new anticancer drugs. Compared to two-dimensional culture, this model has advantages in the width of the therapeutic window, demonstrating the value of studying anticancer drugs in human three-dimensional models.

High performing additively manufactured bone scaffolds based on copper substituted diopside

Shumin Pang et al.

Summary: The addition of small amounts of copper enhances the mechanical and biointegrative performance of bioceramics. 3D scaffolds made from copper-doped diopside were studied, and the results showed improved fracture toughness, antimicrobial activity, and in vitro angiogenesis with low levels of copper. However, excessive copper content led to cytotoxicity. Scaffolds with 0-1% copper substitution demonstrated favorable biocompatibility and cell proliferation.

3D printing of sponge spicules-inspired flexible bioceramic-based scaffolds

Zhibo Yang et al.

Summary: Bioceramics are commonly used in bone tissue repair and regeneration due to their desirable biocompatibility and bioactivity. However, their brittleness limits their clinical applications. Inspired by the properties of sponge spicules, researchers combined 2D bioceramics and 3D printing to construct flexible bioceramic-based scaffolds with spicule-like concentric layered biomimetic microstructures. These scaffolds exhibit enhanced flexibility and toughness compared to traditional scaffolds, allowing for various shape changes without fracture, and demonstrate improved in vitro and in vivo bone-forming bioactivity compared to conventional scaffolds.

Bone tissue regeneration: The role of finely tuned pore architecture of bioactive scaffolds before clinical translation

Ronghuan Wu et al.

Summary: The spatial dimension of pores and interconnection within macroporous scaffolds plays a critical role in facilitating cell migration and bone tissue growth. This study evaluated biological performances of nonstoichiometric bioceramic scaffolds with varying pore dimensions in a femoral bone defect model, showing that scaffolds with larger pore sizes promote neotissue ingrowth and enhanced bone regeneration and remodeling. These findings provide important insights into how porous architecture influences bone regeneration in vivo and suggest potential implications for optimizing scaffold design using advanced additive manufacturing techniques.

Clean Bioprinting - Fabrication of 3D Organ Models Devoid of Animal Components

Johanna Berg et al.

Summary: Bioprinting technology enables precise positioning of living cells in bio-materials to fabricate tissues and organs, with the potential for organ transplantation and research. However, current bioprinting procedures often involve animal-derived components, prompting the development of strategies to replace these with synthetic or plant-based materials. Aiming for animal component-free bioprinting, known as clean bioprinting, involves adapting cells to FBS-free media and using bioinks of human origin.

Finite Element Analysis of Porosity Effects on Mechanical Properties for Tissue Engineering Scaffold

Muhammad Azfar bin Noordin et al.

Summary: Porosity is crucial in tissue engineering scaffolds as it affects biocompatibility and cell proliferation. Balancing porosity with mechanical properties is important in scaffold design. This study aimed to find a scaffold geometry that maintains high porosity while exhibiting good mechanical properties, using Circle and square geometries in Finite Element Analysis. The results showed that smaller pore size models had higher Young's Modulus while maintaining porosity above 80%.
