With the increasing incidence of bone defects in clinical practice, demand for grafts or substitutes has become more urgent. Polydopamine (PDA)-coated tissue engineering materials offer a promising alternative such cases. PDA coating is characterized by solid formed polymerization dopamine under alkaline and oxygen-containing conditions, which can provide implants good hydrophilicity through active functional groups contained structure. More importantly, strong adhesion an anchor between implant drugs to achieve modification surface enhance regeneration. In this review, different effects derivatives their current research were summarized. The mechanisms underlying promoting regeneration have also discussed detail, providing theoretical basis application PDA. Finally, series PDA-coated promotion repair been summarized discussed. This review provides cutting-edge design ideas PDA-based biomaterials highlights treatment strategies defects.

Progress in the design principle of biomedical tissue adhesive hydrogel with naturally derived substance

Journal of Polymer Science, Год журнала: 2024, Номер 62(19), С. 4341 - 4359

Опубликована: Фев. 28, 2024

Abstract In recent years, natural substance‐based tissue adhesive hydrogels have been widely studied by researchers because of their practicability and affordability. this review, we summarized the design principles mechanisms for constructing from perspective polyphenols (catechol, dopamine, tannic acid), cationic polymers (chitosan, lysine, antibacterial peptides), polysaccharides other substances. addition, according to morphology size hydrogels, it was divided into macroscopic microscopic hydrogels. Therefore, such as injectable hydrogel patches including microspheres were reviewed. Furthermore, review provided outlook based on present The aimed summarize progress in provide a valuable reference development its applications biomedical field.

Injectable photosensitive bone cement enhancing angiogenesis and osteogenic differentiation for the treatment of bone nonunion

APL Bioengineering, Год журнала: 2025, Номер 9(1)

Nonunion fractures present a significant clinical challenge because of their complex microenvironment, which includes poor vascularization, insufficient osteogenesis, infection, and separation fracture ends. The current treatments have certain limitations. Inspired by this phenomenon, sandcastle worms secrete adhesive proteins that bind sand grains, shell fragments, mineral particles, thereby constructing “castles.” In study, we developed an injectable bone cement using methacryloyl chitosan (CSMA) combined with specific concentration oyster nanoparticles (OS-np) to treat nonunion fractures. Oyster shells are composed primarily calcium carbonate, releases ions promote angiogenesis osteogenesis. in vivo results at 8 weeks showed the expression BMP2, RUNX2, VEGF OS-np/CSMA group was increased 5.47, 4.38, 3.54 times, respectively, compared control group, significantly enhancing vascularization repair model. injectability ensures it can adapt well structures sites, providing supportive matrix for new formation. Both vitro osteogenesis experiments demonstrated enhanced models, synergistic effects ion release bioactive properties nanoparticles. This study highlights potential as promising treatment strategy effectively promotes
