Various biomaterials have been used to establish these 3D models, enabling the study of cancer cell behavior within different matrices. Hyaluronic acid (HA), a key component of the extracellular matrix (ECM) in tumor tissues, has been widely studied and employed in the development of multiple cancer models. This review first examines the role of HA in tumors, including its function as an ECM component and regulator of signaling pathways that affect tumor progression. It then explores HA-based models for various cancers, focusing on HA as a central component of the 3D matrix and its mobilization within the matrix for targeted studies of cell behavior and drug testing. The tumor models discussed included those for breast cancer, glioblastoma, fibrosarcoma, gastric cancer, hepatocellular carcinoma, and melanoma. The review concludes with a discussion of future prospects for developing more robust and high-throughput HA-based models to more accurately mimic the tumor microenvironment and improve drug testing. Impact Statement This review underscores the transformative potential of hyaluronic acid (HA)-based hydrogels in developing advanced tumor models. By exploring HA's dual role as a critical extracellular matrix component and a regulator of cancer cell dynamics, we highlight its unique contributions to replicating the tumor microenvironment. The recent advancements in HA-based models provide new opportunities for more accurate studies of cancer cell behavior and drug responses. Looking ahead, these innovations pave the way for high-throughput, biomimetic platforms that could revolutionize drug testing and accelerate the discovery of effective cancer therapies.</p>","PeriodicalId":23154,"journal":{"name":"Tissue engineering.

This study aimed to determine the effects of growth differentiation factor 5 (GDF5)-induced rabbit MSCs (rbMSCs) on infraspinatus tendon healing in a New Zealand white rabbit model. In this study, bone marrow-derived rbMSCs were isolated, and 100 ng/mL GDF5 was used to induce tenogenic differentiation in rbMSC. The effects of GDF5 on rbMSC &lt;i&gt;in vitro&lt;/i&gt; were assessed by total collagen assay, gene expression analysis, and immunofluorescence staining of tenogenic markers; native tenocytes isolated from rabbit tendon were used as a positive control. In &lt;i&gt;in vivo&lt;/i&gt;, a window defect was created on the infraspinatus tendons bilaterally. After 3 weeks, the rabbits (&lt;i&gt;n&lt;/i&gt; = 18) were randomly divided into six groups and repaired with various interventions: (1) surgical suture; (2) fibrin glue (FG); (3) suture and FG; (4) suture, FG, and rabbit tenocytes (rbTenocyte); (5) suture, FG, and rbMSCs, and (6) suture, FG, and TMSC. All animals were euthanized at 6 weeks postoperatively. The &lt;i&gt;in vitro&lt;/i&gt; GDF5-induced rbMSCs (or TMSC) showed increased total collagen expression, augmented scleraxis (&lt;i&gt;SCX&lt;/i&gt;), and type-I collagen (&lt;i&gt;COL1A1&lt;/i&gt;) mRNA gene expression levels. Immunofluorescence showed similar expression in GDF5-induced rbMSC to that of rbTenocyte. &lt;i&gt;In vivo&lt;/i&gt; histological analysis showed progressive tendon healing in the TMSC-treated group; cells with elongated nuclei aligned parallel to the collagen fibers, and the collagen fibers were in a more organized orientation, along with macroscopic evidence of tendon callus formation. Significant differences were observed in the cell-treated groups compared with the non-cell-treated groups. Histological scoring showed a significantly enhanced tendon healing in the TMSC- and rbMSC-treated groups compared with the rbTenocyte group. The &lt;i&gt;SCX&lt;/i&gt; mRNA expression levels, at 6 weeks following repair, were significantly upregulated in the TMSC group. Immunofluorescence showed COL-1 bundles aligned in parallel orientation; this was further confirmed in atomic force microscopy imaging. SCX, TNC, and TNMD were detected in the TMSC group. In conclusion, GDF5 induces tenogenic differentiation in rbMSCs, and TMSC enhances tendon healing &lt;i&gt;in vivo&lt;/i&gt; compared with conventional suture repair. Impact Statement Tendon tears and degeneration are debilitating clinical conditions. To date, the suture method is the only gold standard for repairing tendons. Mesenchymal stromal cells (MSCs) have been suggested for many years for their potential in tissue regeneration, especially in tendon-degenerative conditions. Growth differentiation factor 5 (GDF5) has been reported to induce human MSC into a tenogenic lineage (or TMSC), hence a potential cell source for tendon regeneration.

With scientific progress, experimental models have become increasingly complex over time. This complexity sometimes blurs the distinction between categories, making terminology less consistent. In biomedical research, three overarching terms are commonly used to characterize experimental environments: <i>in vitro</i>, <i>ex vivo</i>, and <i>in vivo</i>. While <i>in vitro</i> translates from Latin as \"in glass,\" referring historically to experimental conditions in a test tube or petri dish, <i>in vivo</i> experiments occur within a living organism's natural environment. Conversely, <i>ex vivo</i> originates from living tissue outside its host environment while striving to maintain conditions as close to the host surroundings as possible. In the tissue engineering and regenerative medicine (TE&RM) community, there needs to be more clarity between <i>in vitro</i> and <i>ex vivo</i> terminology, with historical definitions sometimes disregarded and new terms often introduced without rigorous scientific justification. At this juncture, the question arises of when to refer to experiments as <i>in vitro</i> or <i>ex vivo</i> or whether the terms may be used synonymously in some instances. Moreover, what criteria must <i>ex vivo</i> experiments meet to be legitimately defined as such? This perspective is intended to address questions that would assist the TE&RM community in better understanding the differences between <i>in vitro</i> and <i>ex vivo</i> models. Impact Statement In the tissue engineering & regenerative medicine literature, the terms \"in vitro\" and \"ex vivo\" are often used interchangeably to describe experiments. This interchangeable usage can lead to a compromised interpretation of research results and, consequently, misleading scientific conclusions and teachings. This perspective aims to provide clarity on the various definitions of experimental designs.

We define, summarize, and discuss the differentiation potential of totipotent, pluripotent, and multipotent stem cells, emphasizing the advantages and shortcomings of cell therapy for bone repair and regeneration. The fundamental role of mesenchymal stem cells is highlighted due to their multipotency to differentiate into the key lineage cells including osteoblasts, osteocytes, and chondrocytes, which are crucial for bone formation and remodeling. Hematopoietic stem cells (HSCs) also play a significant role; immune cells such as macrophages and T-cells modulate inflammation and tissue repair. Osteoclasts are multinucleated cells that are important to bone remodeling. Vascular progenitor (VP) cells are critical to oxygen and nutrient supply. The dynamic interplay among these lineages and their microenvironment is essential for effective bone restoration. Therapies involving cells that are more than \"minimally manipulated\" are controversial and include embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). ESCs, derived from early-stage embryos, possess pluripotent capabilities and have shown promise in preclinical studies for bone healing. iPSCs, reprogrammed from somatic cells, offer personalized medicine applications and can differentiate into various tissue-specific cell lines. Minimally manipulative cell therapy approaches such as the use of bone marrow aspirate concentrate (BMAC), exosomes, and various biomaterials for local delivery are explored for their effectiveness in bone regeneration. BMAC, which contains mostly immune cells but few mesenchymal and VPs, probably improves bone healing by facilitating paracrine-mediated intercellular communication. Exosome isolation harnesses the biological signals and cellular by-products that are a primary source for cell crosstalk and activation. Safe, efficacious, and cost-effective strategies to enhance bone healing using novel cellular therapies are part of a changing paradigm to modulate the inflammatory, repair, and regenerative pathways to achieve earlier more robust tissue healing and improved physical function. Impact Statement Stem cell therapy holds immense potential for bone healing due to its ability to regenerate damaged tissue. Nonmanipulated bone marrow aspirate contains mesenchymal stem cells that promote bone repair and reduce healing time. Induced pluripotent stem cells offer the advantage of creating patient-specific cells that can differentiate into osteoblasts, aiding in bone regeneration. Other delivery methods, such as scaffold-based techniques, enhance stem cell integration and function. Collectively, these approaches can improve treatment outcomes, reduce recovery periods, and advance our understanding of bone healing mechanisms, making them pivotal in orthopedic research and regenerative medici","PeriodicalId":23154,"journal":{"name":"Tissue engineering.

Developing robust <i>in vitro</i> systems to study FGF23-regulating mechanisms is crucial for advancing our knowledge and identifying potential therapeutic targets. The traditional <i>in vitro</i> 2D culture system results in relatively low expression of FGF23, complicating further exploration of its regulatory mechanisms and potential therapeutic targets. Herein, we reported a high-throughput approach to generate preosteoblastic cell spheroids with enhanced FGF23 production. For this purpose, murine preosteoblast cell line (MC3T3-E1) was cultured in our previously reported nonadherent microwells (200 µm in diameter, 148 µm in depth, and 100 µm space in between) and self-assembled into spheroids with a diameter of 92.3 ± 15.0 µm after 24 h. Compared with monolayer culture, the MC3T3-E1 spheroids showed a significant upregulation of FGF23 in both gene and protein levels after 24 h of serum-free induction. RNA sequencing and western blotting analysis further suggested that the enhanced FGF23 production in MC3T3-E1 spheroids was attributed to the activation of the parathyroid hormone (PTH)/PTH1R signaling pathway. Impressively, inhibition of PTH signaling through small molecular inhibitors or short hairpin RNA targeting PTH1R effectively reduced FGF23 production. In summary, the current study revealed the efficacy of the high-throughput formation of preosteoblast cell spheroid in stimulating FGF23 expression for mechanistic studies.

Unfortunately, repairing these defects remains difficult because of the poor regenerative properties of cartilage and complex mechanical demands of the joint. As such, the field of tissue engineering aims to develop multiphasic implants that replace pathological cartilage and bone tissue and restore mechanical functionality to the joint. Recent bone physiology investigations have demonstrated that osteoclast (OC) lineage cells are inextricably involved in osteoblastic bone formation through an extensive network of anabolic signaling pathways, and so the codelivery OC and osteoblast (OB) lineage cells within scaffolds is being actively explored for bone tissue engineering purposes. However, it remains unclear how these cells can be incorporated into the design of multiphasic osteochondral scaffolds to potentially enhance subchondral bone formation and subsequent implant osseointegration. To explore this question, we examined direct surface seeding and hydrogel encapsulation as potential scaffold cellularization strategies. First, we examined how OC precursor cells and peripheral blood monocytes (PBMCs) influence early-stage bone matrix development and osteogenesis in 2D coculture. Then, we evaluated the osteogenic potential of mesenchymal stem cells (MSCs) and PBMCs cocultures encapsulated within a gelatin methacrylate (GelMA) hydrogel system. Our findings demonstrate that coculturing PBMCs with MSCs in 2D cultures significantly enhanced cell proliferation, early bone matrix deposition, and the formation of cell clusters by Day 28. However, we observed no significant difference in type I collagen deposition between GelMA hydrogel scaffolds cultured in basal and OC conditions during the same period. In addition, we found that the GelMA hydrogel system with MSC/PBMC cocultures in OC conditions exhibited decreased osteogenic activity by Day 28. Collectively, our findings support the osteogenic potential of OC-lineage cells in 2D culture conditions, and the potential benefits of surface-seeding for the codelivery of OC-lineage cells and MSCs in osteo-scaffolds for enhanced osteochondral regeneration and broader bone tissue engineering purposes.</p>","PeriodicalId":23154,"journal":{"name":"Tissue engineering.
