Despite numerous experimental achievements and convincing preclinical outcomes, MSC-based cell sheets have yet to reach the stage of a clinically reproducible product. This gap reflects not so much the technological limitations of the method as an incomplete understanding of its biological nature. MSC-based cell sheets represent more than a vehicle for cell delivery; they are self-organizing systems governed by intrinsic biophysical and morphogenetic principles. Their structural maturation involves (1) cellular condensation, (2) extracellular matrix deposition, and (3) contractile remodeling-processes that mirror the early phases of granulation tissue formation. Viewing the cell sheet as an <i>in vitro</i> model of connective tissue regeneration opens new research avenues extending beyond its therapeutic applications. This review summarizes the key milestones in the development of MSC-derived cell sheet technology, identifies major challenges and conceptual inconsistencies, and discusses the potential of studying these constructs as autonomous biological systems. The integration of mechanobiology, spatial omics technologies, and tissue engineering approaches may help reconceptualize MSC-based cell sheets both as tools for translational therapy and as a fundamental model for studying self-organizing regenerative processes.</p>","PeriodicalId":23134,"journal":{"name":"Tissue Engineering.

This review highlights the recent advances in the application of DFSCs and biological scaffolds for regenerative medicine, with a focus on oral and craniofacial tissue. DFSCs exhibit key advantages for regenerative therapies, including high accessibility, robust self-renewal capacity, and multipotent differentiation potential, enabling their differentiation into odontogenic (dentin- and enamel-forming), osteogenic, and fibroblastic lineages. We discuss the embryonic origin of DFSCS and their unique ability to maintain stable cellular properties in long-term <i>in vitro culture</i>. Importantly, DFSCs play a pivotal role in tooth morphogenesis, periodontal tissue formation, and craniofacial bone regeneration, making them promising for functional oral tissue restoration. A critical aspect of DFSC-based regeneration is the integration with bioactive scaffolds, which provide structural support, promote cell adhesion, proliferation, and differentiation, and facilitate vascularization. We analyze how scaffold properties, such as biodegradability, porosity, and permeability, influence DFSC behavior and therapeutic outcomes. Finally, we explore future challenges and opportunities in optimizing DFSC-scaffold interaction, emphasizing advancements in biomaterial design and emerging bioengineering technologies. Preliminary evidence suggests that integrating DFSCs with engineered scaffold systems may offer potential benefits for personalized regenerative therapies, though further validation is required before clinical translation.

Dormant CRC cells disseminated following initial primary tumor resection or treatment often resurface years later to form aggressive, therapy-resistant tumors that result in high patient mortality. Routine imaging-based screenings often fail to detect dormant cancer cell clusters, and there are no overt symptomatic presentations, making dormant CRC a major clinical challenge to diagnose and treat. Tissue engineering approaches are ideally suited to model dormant cancer cells and enable the discovery of therapeutic vulnerabilities or unique mechanistic dependencies of dormant CRC. Emerging evidence suggests that tissue-engineered approaches have been successfully used to model dormant breast and lung cancer. With CRC responsible for the second most cancer-related deaths worldwide and CRC patients commonly experiencing recurrence, it is essential to expand dormancy models to understand this phenomenon in the context of CRC. Most published <i>in vitro</i> models of CRC dormancy simplify the complex tumor microenvironment with two-dimensional culture systems to elucidate dormancy-driving mechanisms. Building on this foundation, future research should apply tissue engineering methods to this growing field to generate competent three-dimensional models and increase mechanistic knowledge. This review summarizes the current state of <i>in vitro</i> CRC dormancy models, highlighting the techniques utilized to give rise to dormant CRC cells: nutrient depletion, anticancer drugs, physical extracellular matrix interactions, and genetic manipulation. The metrics used to validate dormancy within each model are also consolidated to demonstrate the lack of established standards and the ambiguity around comparing studies that have been validated differently. The methods of these studies are organized in this review to increase comprehensibility and identify needs and opportunities for future bioengineered <i>in vitro</i> models to address dormancy-driven mortality in patients with CRC liver metastasis.</p>","PeriodicalId":23134,"journal":{"name":"Tissue Engineering.

The pericellular matrix (PCM) is critical for transducing biophysical stimuli to the articular chondrocytes (ACs) that it envelops. Given the mechanobiological sensitivity of ACs, it is pivotal in maintaining the chondrogenic phenotype and the production of extracellular matrix (ECM) during articular cartilage tissue engineering. While the maintenance of the native PCM significantly improves the quality of neocartilage, current isolation methods are limited. A solution to this challenge is facilitating ACs to regenerate their PCM. However, the regulation of PCM synthesis remains poorly understood, hindering the development of effective tissue engineering strategies. This narrative review aims to provide a comprehensive analysis of the complex interplay between extracellular cues and intracellular pathways regulating PCM synthesis during articular cartilage tissue engineering. Our analysis reveals that mechanical cues, such as material stiffness and mechanical stimulation, are the primary regulators of PCM synthesis. Additionally, the use of scaffold-free techniques potentially affects the structuring of newly created PCM. Tuning these stimuli can significantly impact the quality of the formed PCM, ultimately influencing neocartilage quality. Furthermore, we highlight intracellular mechanisms involved in the transduction of these extracellular cues, including actin polymerization, yes-associated protein and transcriptional coactivator with PDZ-binding motif localization, and transforming growth factor beta-induced Smad signaling. Although the current literature suggests the involvement of these signaling pathways in regulating the synthesis of PCM components, we found that studies investigating these processes in ACs are lacking. Elucidating the relationships between extracellular stimuli, intracellular signaling, and the expression of PCM components could provide a framework for designing new cartilage tissue engineering approaches that facilitate proper PCM synthesis. Ultimately, this can improve ECM quality and advance articular cartilage regeneration.</p>","PeriodicalId":23134,"journal":{"name":"Tissue Engineering.
