Regulated macrophage immune microenvironment in 3D printed scaffolds for bone tumor postoperative treatment

Construction of multifunctional hydrogel with metal-polyphenol capsules for infected full-thickness skin wound healing

“…Methacrylated hyaluronic acid (HAMA) was synthesized according to modified synthetic methods reported in the literature [ 30 ]. 1 g of HA was completely dissolved in 100 mL of ultra-pure water.…”

Recent advances in hydrogels for preventing tumor recurrence

“…Natural polymers have been extensively applied in the construction of hydrogels in biomedical fields as they exhibit outstanding biocompatibility and biodegradability, as well as no evident long-term inflammatory response. [37][38][39][40][41] In recent studies, numerous natural polymers including chitosan, [42][43][44][45][46][47][48] hyaluronic acid, [49][50][51] agarose, 52,53 sodium alginate, [54][55][56][57] fibrin 58,59 and silk fibroin [60][61][62][63] have been used to prevent postsurgical recurrence.…”

Small Joint Organoids 3D Bioprinting: Construction Strategy and Application

“…These groups serve to shield the bone repair site from harmful growth factors in the microenvironment (Figure 6c). [77] The reason for choosing CS in materials for cartilage repair and cartilage organoids is that it is a widely distributed glycosaminoglycan that plays an important role in cartilage and the extracellular matrix. The cartilage generated by the cartilage organoids constructed by Sun et al exhibited substantial deposition of glycosaminoglycans and abundant expression of type II collagen.…”
