This study compared the structural properties of four different commercially available micronized products derived from either reconstituted collagen (pRC), urinary bladder matrix (pUBM), or ovine forestomach matrix (mOFM, mOFMµ). The test articles were characterized by laser diffraction analysis, scanning electron microscopy (SEM), micro-computed tomography (micro-CT), packing density, differential scanning calorimetry, rheometry, proteolytic stability, agarose gel electrophoresis, and blood clotting index. Particle size and surface morphology, assessed by laser diffraction, SEM, and micro-CT, revealed marked differences in particle size, shape, and aggregation. Packing density ranged from 80.3 ± 2.7 mg/cm<sup>3</sup> (mOFM) to 484.7 ± 17.8 mg/cm<sup>3</sup> (pRC). Thermal analysis demonstrated the native structure of the OFM-based test articles (T<sub>m</sub>, 59.80 ± 0.11°C and 58.15 ± 0.15°C) relative to pUBM and pRC (T<sub>m</sub>, 41.06 ± 0.06°C and 40.59 ± 0.23°C). Rheological testing revealed that mOFM and mOFMµ had increased cohesive energy, indicating better mechanical resilience when the micronized materials were rehydrated to form a paste. The OFM-based test articles exhibited the greatest resistance to proteolytic digestion (T<sub>1/2</sub>, 12.730 ± 1.232 and 5.759 ± 0.1296). All the test articles, except for the reconstituted collagen product, demonstrated hemostasis in whole blood. Micronized reconstituted collagen showed immediate dissolution and no fluid absorption, hemostasis, or resistance to proteolytic digestion, whereas micronized OFM showed the greatest proteolytic stability and packing density. Substantial differences among the micronized bioscaffolds were revealed from the analysis, most likely due to their different source materials and manufacturing processes.

We also evaluate dECM's impact on cell viability and differentiation potential. Human dermal fibroblasts were decellularized using nonidet P-40, a nonionic detergent (nonyl phenoxypolyethoxylethanol) (NP-40) lysis buffers (1% or 10%) for 1 or 3 h. Decellularization efficacy was assessed via double-stranded DNA (dsDNA) Qubit assay, gel electrophoresis, immunofluorescence, and bicinchoninic acid protein assay. Hydrogels (5 wt% alginate, 3 wt% gelatin) with/without 1% dECM were extrusion bioprinted. Structural and mechanical properties were analyzed using Raman spectroscopy and rheology. Fibroblast viability within bioprinted constructs was monitored over 21 days. Hoechst staining and Qubit assay confirmed residual DNA after 1-h incubations, but complete removal (<50 ng dsDNA) occurred after 3 h with both NP-40 concentrations. The 10% NP-40/3-h protocol yielded the highest protein content. dECM incorporation did not compromise scaffold properties. Significantly enhanced cell viability and glycosaminoglycan (GAG) content (up to day 6) were observed in dECM hydrogels versus controls. Mechanical testing showed a 33% increase in Young's modulus in dECM-containing hydrogels. Raman spectroscopy confirmed successful dECM integration via a characteristic GAG peak (895 cm<sup>-1</sup>).

This protocol provides a robust and standardized source of bioactive dECM, offering a viable alternative to tissue-derived matrices for advanced bone and cartilage tissue engineering bioinks.

Despite significant advancements in conventional bone tissue engineering, the simulation of the intricate microenvironment characteristic of natural bone tissue remains inadequate. Natural bone is characterized by intricate macroscopic and microscopic architectures, along with a dynamic microenvironment that facilitates processes such as bone formation, remodeling, and repair. Bone organoids-three-dimensional structures that emulate natural bone tissue derived from stem cells-represent a substantial advancement in both bone tissue engineering and precision medicine. These organoids present a promising pathway for enhancing our understanding of bone biology and disease mechanisms. Their unique potential within precision medicine is underscored by their applications in personalized drug testing, disease modeling, and as platforms for regenerative therapies. As this field continues to progress, bone organoids are poised to play an essential role in developing tailored treatment strategies for disorders related to bones. In this review, we summarize the roles of cell types, biomaterials and culture techniques in the construction of bone organoids, and emphasize the key significance of microenvironment in guiding the maturation of bone organoids. In addition, we will discuss the standardization, current limitations, and future directions of bone organoids to provide insights for research and clinical applications.</p>","PeriodicalId":56375,"journal":{"name":"Tissue Engineering Part A","volume":" ","pages":"185-199"},"PeriodicalIF":2.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144627871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
