Summary: The growing interest in bioengineering in-vivo-like 3D functional tissues has led to novel approaches to biomanufacturing and expanded applications. Microgravity, as seen in spaceflight, has potential benefits to tissue engineering but cannot be completely replicated on Earth. Bioengineered microphysiological systems provide an attractive research model due to the practical challenges of conducting research in space. This review summarizes published research on the use of real and simulated microgravity to improve biomanufacturing and model human diseases, discussing platforms, applications, and achievements.

Summary: Medical imaging and 3D bioprinting can be used to create patient-specific bone scaffolds with complex shapes and controlled inner architectures. This study investigates the effectiveness of a biomimetic approach to scaffold design and demonstrates that the biomimetic scaffold with a dense external layer improves bone regeneration compared to the control scaffold. Histological examination confirms the superior bone regeneration in the biomimetic scaffolds and suggests that patient-specific anatomy can be accurately translated into a 3D bioprinting strategy, leading to clinically relevant constructs.

Summary: Additive manufacturing (AM) has significant advantages in the fabrication of tissue engineering implants. However, many tissue constructs have anisotropic heterogeneous structures, which pose challenges for conventional AM processes. Multimaterial 3D and 4D bioprinting offer a promising solution for constructing multifunctional implants with heterogeneous structures that can better mimic the host microenvironment.

Summary: The study utilized a microfluidic approach to prepare collagen microbeads loaded with human bone marrow derived mesenchymal stem cells for creating engineered bone grafts. The cell-laden microbeads self-assembled into macro-tissues, enabling precise control over cell spatial distribution at the macroscale, offering flexibility for graft volume and architecture.

Summary: This study introduces a method to engineer controlled microporosity in 3D bioprinted hydrogels using microgel-templated porogel (MTP) bioinks. By fabricating templated gelatin microgels with different sizes and mixing them with photo-crosslinkable formulations, the researchers achieved consistent printability and the formation of micropores in situ. This approach provides a facile strategy to compensate for the limited resolution of current bioprinting approaches and engineer precise micropores in 3D printed structures.

Summary: Fluorescent nanodiamonds (FNDs) with negative nitrogen-vacancy (NV-) defect centers are ideal probes for biosensing applications and can potentially serve as biomarkers for cell differentiation. The uptake of FNDs by THP-1 monocytes and monocyte-derived M0-macrophages is studied, revealing differing FND-cell interactions and time-dependent uptake. FND uptake allows for distinction between cell subtypes based on phagocytic capacity, and FNDs demonstrate effective cell labeling and have potential for sensing biological processes involving cell differentiation.

Summary: This study introduces a customized hanging insert for cultivating Caco-2 cells on hydrogel membranes under flow conditions. The device consists of an apical channel-like chamber for cell culture with shear force and a basolateral chamber that is mixed when rocked. The experiment investigates the impact of seeding density and flow on the growth of the cells. The results show that low seeding density and flow promote the formation of three-dimensional structures and improve barrier function.

Summary: In the past decade, embedded 3D printing has emerged as a powerful tool for biofabrication of soft tissue constructs. However, the available granular gel support media have lacked the cell-adhesive and cell-instructive functions. To address this, a methodology for the generation of self-healing annealable particle-extracellular matrix (SHAPE) composites has been developed, which allows for both high-fidelity printing and adjustable biofunctional extracellular environment. This study demonstrates the precise biofabrication of human neural constructs using SHAPE composites.

Summary: This paper establishes a physics-based simulation framework for steering a magnetically actuated guidewire based on the linear elasticity and dipoles theories. The framework employs a simplified integration scheme based on the finite-volume method to model the guidewire using the linear elasticity theory and forces resulting from the interference of magnetic fields. Simulations illustrate the approach performance on a soft rod, demonstrating its potential for constructing rapid models for continuum manipulators in practice.
