Summary: With the advancement in understanding bone regeneration mechanisms and development of bone tissue engineering, a variety of scaffold carrier materials called hydrogels have emerged. Hydrogels are biocompatible, have unique swelling properties, and are relatively easy to fabricate, making them increasingly popular in bone regeneration and tissue engineering. Hydrogel drug delivery systems consist of cells, cytokines, an extracellular matrix, and small molecule nucleotides, each with different properties based on their chemical or physical cross-linking. This paper summarizes recent research in the field of bone regeneration using hydrogels as delivery carriers, discusses their application in bone defect diseases and their mechanisms, and explores future research directions of hydrogel drug delivery systems in bone tissue engineering.

Summary: This study aimed to evaluate the therapeutic effect of combining canine bone marrow mesenchymal stem cells (cBMSCs) with gelatin-nano-hydroxyapatite (Gel-nHAP) on bone defect diseases in dogs. The results showed that Gel-nHAP supported the attachment of cBMSCs and exhibited good biocompatibility. In animal experiments, significant cortical bone growth was observed in the Gel-nHAP group at week 8 and in the cBMSCs-Gel-nHAP group at week 4.

Summary: Extracellular vesicles (EVs) are one of the main mechanisms of communication between cells and the surrounding tissue or at distance. Recent studies have revealed the molecular composition and clinical indications of EVs derived from adult mesenchymal stromal cells (MSCs). These EVs maintain some of the properties of their parent cells and have important implications for cell-free therapies.

Summary: Both adipose-derived and bone marrow-derived mesenchymal stem cells (ADSCs and BMSCs) can suppress renal fibrosis, with ADSCs showing a stronger effect under serum-containing culture conditions. However, ADSC infusion in mice may lead to a higher death rate from pulmonary embolism. Therefore, the selection of ADSCs or BMSCs for clinical applications should consider the target disease and culture method.

Summary: This study evaluated the new bone formation potential of MBCP and Bio-Oss grafting materials with DPSCs and BMSCs in a rabbit calvarial bone defect model. The results demonstrated that autogenous bone is the gold standard, and both DPSCs and BMSCs enhanced the osteoconductive capacities of MBCP and Bio-Oss. Moreover, the efficiency of BMSCs combined with MBCP and Bio-Oss was comparable to that of autogenous bone after 8 weeks of healing.

Summary: The study found that allogeneic BMSCs can promote bone regeneration to some extent and gradually match the efficacy of autologous BMSCs after a period of time. In terms of immune response, allogeneic BMSCs caused a weaker immune response in vivo and the bone regeneration effects gradually matched those of autologous BMSCs.

Summary: In this study, nano-deer bone meal was successfully prepared and found to have a higher Ca/P ratio and enriched beneficial trace elements compared to cow bone. The nano-deer bone meal showed good biocompatibility and met the standards of medical biomaterials. Cell function studies demonstrated its excellent performance in the proliferation and differentiation of bone marrow mesenchymal stem cells. These findings suggest the potential use of nano-deer bone meal as an active nanomaterial in bone tissue engineering.

Summary: This study created chemically defined three-dimensional surfaces for large-scale cell expansion by applying a synthetic polymer coating on commercially available polystyrene microcarriers, providing a reproducible surface without relying on xenogeneic serum proteins. These microcarriers not only improved the adhesion of hMSC in serum-free media but also allowed efficient cell passage without the use of cleavage enzymes.

Summary: Researchers have developed a 3D RPE-CC model that mimics key features of healthy and AMD/MD eyes while providing modular control over RPE and CC layers. They have found that both RPE and mesenchyme-secreted factors are necessary for the formation of fenestrated CC-like vasculature, and that CC atrophy and/or CNV can be initiated by patient serum or mutant RPE-secreted factors. Additionally, FGF2 and matrix metalloproteinases have been identified as potential therapeutic targets for AMD/MDs.

Summary: Autologous platelet-rich plasma (PRP) is a popular treatment for musculoskeletal tissue injuries due to its favorable safety profile and cost-effectiveness. However, the therapeutic efficacy of PRP for osteoarthritis and damaged cartilage has been inconsistent. In this study, the researchers developed a method to enhance the efficacy of PRP treatment by attenuating a growth factor known to inhibit cartilage repair. The results showed that VEGF-attenuated PRP significantly improved healing of rat OA cartilage compared to conventional PRP treatment or control group. This study provides a new PRP customization method that can be applied to various tissue repair processes.
