Summary: Cancer progression involves remodeling of the tumor microenvironment, particularly changes in mechanical characteristics. Bioengineered polymer hydrogels can be used to explore how these mechanical changes impact cancer cell behavior. This article reviews studies using hydrogel-based models to investigate the effects of different mechanical cues on cancer cells and highlights advanced strategies for recreating the tumor microenvironment's architectural and mechanical features. It is anticipated that these precision hydrogel systems will enhance our understanding of cancer mechanobiology.

Summary: The rigidity of a cell's substrate or extracellular matrix is crucial for regulating cell and tissue functions, and polyacrylamide (PAAm) hydrogels are commonly used cell culture substrates that provide physiologically relevant stiffness. However, preparing PAAm substrates in large batches for high-yield or multiscale cell cultures is currently difficult and time-consuming. This communication presents a simple method to prepare mechanically uniform PAAm hydrogels with reduced time cost and easily accessible materials. The hydrogel supports cell culture in large batches and covers a wide range of stiffness, controlling various cell features. This method enhances the reproducibility of mechanobiology studies and can be easily applied to research requiring large numbers of cells or experimental groups.

Summary: This study revealed a biphasic functional response of primary human T cells to substrate stiffness, which can be influenced by activating antibody density and cellular contractility. T cell morphology was also shown to be modulated by stiffness, while RNA-seq analysis indicated differing trends in upregulated genes and pathways at both ends of the stiffness spectrum.

Summary: T cell immune responses play a crucial role in both physiological and pathological processes. Mechanosensitive receptors in the microenvironment are found to regulate various T cell immune responses, including activation, cytokine production, metabolism, proliferation, and migration, in addition to biochemical cues. These mechanical cues are converted into biochemical signals by force-sensitive receptors in the immune synapse, a phenomenon widely accepted in the emerging field of immunomechanobiology. This review provides insights into immunomechanobiology, specifically focusing on the binding and triggering of mechanosensitive receptors and resulting T cell immune responses.

Summary: Adoptive T cell therapy has great potential for treating cancer and other diseases. However, strategies for maintaining the proliferation and function of T cells post adoptive transfer are lacking. This study introduces an injectable T cell-responsive macroporous hydrogel that enables in situ activation and expansion of T cells, leading to enhanced CD8(+) T cell response and antitumor efficacy. The gel provides a platform for in vivo expansion of engineered T cells in a controlled manner, for timely and effective treatment of diseases.

Summary: Primary bone cancers like osteosarcoma are driven by bone cells with mutations, and their behavior can be influenced by mechanical stimuli in the tumor microenvironment. Fluid flow over the cells' surface was found to change the behavior of osteosarcoma cells, potentially reducing their harmful effects. Sensitivity of bone cells to mechanical changes suggests that modulation of fluid movement or stiffness levels within tumors could be a novel consideration in developing new treatments to prevent cancer progression.

Summary: In recent years, extracellular vesicles (EVs) have emerged as promising biomarkers, cell-free therapeutic agents, and drug delivery carriers. However, the production of EVs remains a challenge. The use of three-dimensional (3D) culture methods, such as scaffolds and bioreactors, has been successful in increasing EV production and enhancing their therapeutic effects. 3D culture methods also provide opportunities to study the role of EVs in disease pathogenesis and improve drug delivery.

Summary: The electrochemical reduction of CO2 (CO2RR) is a promising approach to maintain a carbon cycle balance and produce value-added chemicals. However, conventional CO2RR electrocatalysts suffer from low activity, stability, and selectivity. Taking inspiration from nature, enzyme-inspired and enzyme-mimicking CO2RR electrocatalysts have been developed, enabling the production of C-1 products with high faradaic efficiency. To achieve disruptive change, a systematic design methodology that leverages fundamental mechanisms associated with desired properties in nature and adapts them to engineering applications is advocated.

Summary: Intermittent switching between wet and dry reactant gases can improve performance stability in a polymer electrolyte fuel cell (PEFC) and alleviate the effects of flooding. Two relative humidity (RH) control strategies were investigated, and it was found that proper duration of the dry gas period can prevent fuel cell degradation. Current and temperature distribution mapping was used to analyze the dynamic response during the transitional stages. Intermittent switching between wet and dry reactant gases is an effective method to overcome mass transfer limitations.

Summary: This study aimed to investigate the effect of IL-1 beta and IFN gamma on TDP-43 and p62 aggregation in vitro. The results showed that combined treatment with IL-1 beta and IFN gamma increased the size of p62 aggregates. IL-1 beta increased p62 protein expression, while IFN gamma did not affect p62. IL-1 beta and IFN gamma may influence TDP-43 processing, but did not trigger sIBM-like TDP-43/p62 features.

Summary: Sporadic inclusion body myositis (sIBM) is an idiopathic inflammatory myopathy characterized by invasion of CD8 T cells and aggregation of proteins in the muscle. TDP-43 and p62 are suggested markers for sIBM. This study found that cytotoxic immune cells may contribute to the TDP-43 localization shifts observed in sIBM, but do not induce aggregation of TDP-43 or p62.

Summary: With the increase in life expectancy and health crises, the demand for medical materials is higher than ever. However, reliance on traditional fabrication and disposal methods, which are harmful to the environment and energy intensive, has also increased. Therefore, there is a need for technological adaptations to ensure a more sustainable future for medicine. Nature-inspired solutions, such as surface patterning, additive manufacturing, microfluidics, and synthetic biology, can be engineered into the lifecycle of medical materials at different stages, from raw materials to recycling.
