Article Abstract

Organoids are three-dimensional (3D) cellular structures formed through the differentiation and self-organization of pluripotent stem cells or tissue-derived cells, showing considerable potential in the research on disease mechanism, personalized medicine, and developmental biology. However, the development of organoids is limited by the complex composition, batch-to-batch variations, and immunogenicity of basement-membrane matrix in the current culture system, which hinders the clinical translation and applications of organoids. Hydrogels are highly hydrated 3D polymer network materials, with modifiable mechanical and biochemical properties by engineering, representing an ideal alternative to basement-membrane matrix. This article reviews the research progress in engineered hydrogels with defined composition currently used in organoid culture. We introduce the structural characteristics and engineering design considerations of hydrogels, emphasize the latest research progress and specific application cases, and discuss the future development of these engineered hydrogels, provide valuable insights for the further advancement and optimization of engineered hydrogels for organoid.

Maintaining safe and potent drug levels in vivo is challenging. Multidomain peptides assemble into supramolecular hydrogels with a well-defined, highly porous nanostructure that makes them attractive for drug delivery. However, their ability to extend release is typically limited by rapid drug diffusion.

Acute lymphoblastic leukemia (ALL) preferentially localizes in the bone marrow (BM) and displays recurrent patterns of medullary and extra-medullary involvement. Leukemic cells exploit their niche for propagation and survive selective pressure by chemotherapy in the BM microenvironment, suggesting the existence of protective mechanisms. Here, we established a three-dimensional (3D) BM mimic with human mesenchymal stromal cells and endothelial cells that resemble vasculature-like structures to explore the interdependence of leukemic cells with their microenvironment.

Therapeutic drug monitoring (TDM) is vital for effective optimization of pharmacological treatments. In this study, we engineered a chromatography column that is sensitive to temperature fluctuations, thereby enabling safe and straightforward TDM without relying on organic solvents. Silica beads were modified by applying poly(N-isopropylacrylamide) (PNIPAAm) hydrogels, using a condensation reaction to modify the initiator, followed by radical polymerization to integrate the PNIPAAm hydrogel.

Tumor surgery often leads to tumor residue, tissue defects, and drug-resistant bacterial infections, resulting in high recurrence rates and chronic wounds. In this study, an injectable hydrogel was synthesized using glycidyl trimethyl ammonium chloride-chitosan (GCh) and formylbenzoic acid-modified chrysomycin A (CA)-loaded F127 micelles (F127FA-CA). The formation of the hydrogel is achieved through Schiff base conjugation, which occurs between the amino groups present in GCh and the aldehyde groups located on the micelle surfaces.

The development of effective hemostatic and antibacterial dressings remains a critical challenge in wound management. We report the design and fabrication of novel porous composite hydrogels composed of carboxymethyl cellulose (CMC), silica (SiO), and zinc oxide nanoparticles (ZnO NPs) . The incorporation of SiO and ZnO NPs into the CMC hydrogel matrix resulted in a unique multi-scale porous structure, characterized by interconnected holes of various sizes, which significantly enhanced the hydrogel's liquid absorption capacity and mechanical strength.
