These challenges are mostly attributed to the inadequacies of current methods, characterized by their high variability and the reliance on animal-derived components, such as fetal bovine serum (FBS) in cell culture. To address these shortcomings, our approach diverges from conventional practices by prioritizing consistency and reproducibility, and the complete elimination of animal derivatives throughout the entire process. We have developed a novel method that utilizes a peptide-functionalized photocrosslinkable methacrylated hyaluronic acid (MeHA–RGD) hydrogel as a cell sealant for loading human adipose-derived stem cells (hASCs) into a 3D porous polycaprolactone–tricalcium phosphate (PCL–TCP) scaffold. Additionally, we created a 3D-printed vacuum-assisted cell loading device to facilitate this process and ensure efficiency and consistency during cell loading. Our findings indicate that the MeHA–RGD hydrogel supports both stem cell viability and osteogenic differentiation, demonstrating outcomes comparable to those achieved with fibrin glue, a conventional cell sealant widely used in BTE from autologous or xenogeneic sources, even under serum- and xeno-free conditions. In the pursuit of clinical translation, it is vital that biomaterials exhibit low variability, are easily accessible, readily available, and completely free of animal derivatives. To our knowledge, this is the first study to employ a 3D-printed vacuum-assisted cell loading device system within a fully defined hybrid 3D system under complete serum- and xeno-free conditions. These findings unravel and encourage alternative approaches in addressing the existing challenges in BTE, thereby facilitating and accelerating clinical translation in the future.</p>\u0000 </div>","PeriodicalId":202,"journal":{"name":"Journal of Tissue Engineering and Regenerative Medicine","volume":"2025 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/term/7287217","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144537076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, there is an uncertainty surrounding the timeline on which stimulated iPSC-CMs begin to show early signs of maturation in comparison with their nonstimulated counterparts. Here, we introduce a low-cost custom bioreactor capable of delivering tunable ES to standard 2D cell monolayers. We show that, after exposure to short-term ES, stimulated CMs express early signs of maturation compared to nonstimulated controls. Changes to contractility and protein expression indicate cellular rearrangement within cell monolayers and induction of partial maturation in response to ES. While early signs of maturation are present after 3-4 days of ES, additional cellular structures must develop to reach complete maturation. We also show that this bioreactor can electrically stimulate cardiac fibroblasts (cFBs) and may induce alignment of cFB. We have shown that our custom ES bioreactor can be easily integrated into standard in vitro cell culture platforms to induce measurable changes in both CMs and cFB, exhibiting its potential for promoting crucial CM maturation and cell alignment for cardiac tissue engineering applications.</p>\u0000 </div>","PeriodicalId":202,"journal":{"name":"Journal of Tissue Engineering and Regenerative Medicine","volume":"2025 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/term/3748093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such situations, the development of synthetic bone implants becomes crucial. These implants can be carefully designed and manufactured as potential bone substitutes, offering controlled parameters such as porosity, hardness, and osteogenic cues. In this study, we employed digital light processing (DLP) technology to construct an alumina ceramic scaffold featuring a triply periodic minimal surface (TPMS) structure for bone transplantation. The scaffold was filled with type I collagen to enhance cell infiltration [1], thereby increasing the total surface area. In addition, type I collagen is a carrier for both bone morphogenetic protein-2 (BMP-2) and zoledronic acid (ZA). Using a clinically relevant rabbit cranium defect model, the scaffold underwent in vivo assessment for its functionality in repairing critical-sized bone defect (approximately 8 mm). Four groups of animal experiments were carried out including the control group, the gyroid scaffold group, the type I collagen-loaded scaffold group, and the bioactive factor-functionalized scaffold group. Our animal-based study results revealed that the gyroid scaffold, functionalized with bioactive molecules, provided a conductive surface for promoting increased bone formation and enhancing the healing process in critical-sized long bone and cranium defects.

Drug treatments that reduce cellular senescence may enhance the regenerative capacity of BM-MSCs. This study investigates the effects of losartan and fisetin, both separately and in combination, on cellular senescence and osteogenesis. Human BM-MSCs were exposed to low and high concentrations of each drug for 24 h. Our findings showed that high-dose losartan exhibited cytotoxicity, focusing subsequent analyses on the low doses. Both low-dose losartan and fisetin effectively mitigated cellular senescence, with combined treatment showing synergistic effects in reducing senescence markers. From these initial findings, subsequent experiments utilized low doses of both compounds to evaluate their effect on differentiation capacity. Our multimodal approach, incorporating flow cytometry, senescence-associated heterochromatin foci (SAHF) immunohistochemistry, senescence-associated secretory phenotype (SASP) quantification, and differentiation potential assays, revealed that the combination of 23.6 μM of losartan and 50 μM of fisetin was optimal for reducing cellular senescence and enhancing osteogenesis in BM-MSCs. These results support potential therapeutic strategies to counteract age-related declines in bone health and improve healing. By targeting cellular senescence while promoting osteogenesis, losartan and fisetin offer promising avenues for future research aimed at enhancing the regenerative capacity of BM-MSCs in the context of musculoskeletal regenerative medicine.</p>\u0000 </div>","PeriodicalId":202,"journal":{"name":"Journal of Tissue Engineering and Regenerative Medicine","volume":"2025 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/term/9187855","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
