Abstract
This study reports the preparation of a novel porous 3D scaffold from agarose-snail mucus (AGSMu) for cartilage tissue repair applications. AG is reported for its unique thermal and mechanical properties, biocompatibility, and biodegradability, making it suitable for biomedical applications. Still, it lacks the cell adhesion properties required for tissue engineering applications. SMu is a complex substance identified to contain glycosaminoglycans (GAGs) and other bioactive molecules that promote wound healing and reduce cartilage deterioration and inflammation. Hence, porous 3D blend scaffolds containing AG and SMu were prepared by the freeze-drying method, characterized, and investigated for bioactive effects on human chondrocyte (C28/I2) cells. The scaffolds had a microporous structure with an average pore size of 245 μm. FTIR spectroscopy showed that SMu was successfully incorporated into the scaffolds. The SMu increased the mechanical strength of the composite scaffolds by more than 80% compared to the pristine AG scaffold. The scaffolds were found to be biocompatible with tunable degradation. The human chondrocyte cells attached and proliferated well on the 3D scaffolds in a few days, demonstrating a marked improvement in adhesion due to the presence of SMu. Enhanced cell adhesion and mechanical properties of 3D porous AG scaffolds could make them suitable for articular cartilage repair and regeneration.

Abstract
Craniofacial defects and dental tissue loss have significant negative impacts on the structure and function of jaws and face, often resulting in psychological issues in patients, emphasizing the urgent need for effective craniofacial tissue reconstruction. Unfortunately, natural regeneration of these tissues is limited. Dental-derived mesenchymal stem cells (MSCs) have emerged as a promising resource for tissue engineering-based therapeutic approaches. However, the clinical outcomes of MSC-based transplantation have not met expectations due to various complex reasons, and cellular senescence is recognized as one of the potential mechanisms contributing to the suboptimal results. The quality of MSC decreases during large-scale in vitro expansion, and it is also influenced by the age and the health status of donors. To address these challenges, extensive efforts have been made to developing strategies to combat senescence in tissue engineering, leveraging on current knowledge of underlying mechanisms. This review aims to elucidate the impact of cell senescence in craniofacial and dental regeneration and provides an overview of state-of-the-art antisenescence strategies. We first discuss the potential factors that trigger cell senescence in craniofacial tissue engineering. Then we describe senescence biomarkers, monitoring methods for senescent MSCs, and their underlying molecular mechanisms. The primary focus of this review is on current strategies to inhibit and alleviate cell senescence in tissue engineering. We summarize the strategies concerning the prevention of cell senescence, senolysis, modulation of the senescent associated secretory phenotype, and reversal of senescent MSCs, offering promising opportunities to overcome the challenges associated with cell senescence in craniofacial tissue engineering.

Automated Nanodroplet Dispensing for Large-Scale Spheroid Generation via Hanging Drop and Parallelized Lossless Spheroid Harvesting. MICROMACHINES 2024; 15:231. [PMID: 38398960 PMCID: PMC10893090 DOI: 10.3390/mi15020231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 01/14/2024] [Accepted: 01/19/2024] [Indexed: 02/25/2024]
Abstract
Creating model systems that replicate in vivo tissues is crucial for understanding complex biological pathways like drug response and disease progression. Three-dimensional (3D) in vitro models, especially multicellular spheroids (MCSs), offer valuable insights into physiological processes. However, generating MCSs at scale with consistent properties and efficiently recovering them pose challenges. We introduce a workflow that automates large-scale spheroid production and enables parallel harvesting into individual wells of a microtiter plate. Our method, based on the hanging-drop technique, utilizes a non-contact dispenser for dispensing nanoliter droplets of a uniformly mixed-cell suspension. The setup allows for extended processing times of up to 45 min without compromising spheroid quality. As a proof of concept, we achieved a 99.3% spheroid generation efficiency and maintained highly consistent spheroid sizes, with a coefficient of variance below 8% for MCF7 spheroids. Our centrifugation-based drop transfer for spheroid harvesting achieved a sample recovery of 100%. We successfully transferred HT29 spheroids from hanging drops to individual wells preloaded with collagen matrices, where they continued to proliferate. This high-throughput workflow opens new possibilities for prolonged spheroid cultivation, advanced downstream assays, and increased hands-off time in complex 3D cell culture protocols.

Evaluation of the Composite Skin Patch Loaded with Bioactive Functional Factors Derived from Multicellular Spheres of EMSCs for Regeneration of Full-thickness Skin Defects in Rats. Curr Stem Cell Res Ther 2024; 19:1142-1152. [PMID: 37694794 DOI: 10.2174/1574888x19666230908142426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 07/24/2023] [Accepted: 08/03/2023] [Indexed: 09/12/2023]
Abstract
BACKGROUND Transplantation of stem cells/scaffold is an efficient approach for treating tissue injury including full-thickness skin defects. However, the application of stem cells is limited by preservation issues, ethical restriction, low viability, and immune rejection in vivo. The mesenchymal stem cell conditioned medium is abundant in bioactive functional factors, making it a viable alternative to living cells in regeneration medicine. METHODS Nasal mucosa-derived ecto-mesenchymal stem cells (EMSCs) of rats were identified and grown in suspension sphere-forming 3D culture. The EMSCs-conditioned medium (EMSCs-CM) was collected, lyophilized, and analyzed for its bioactive components. Next, fibrinogen and chitosan were further mixed and cross-linked with the lyophilized powder to obtain functional skin patches. Their capacity to gradually release bioactive substances and biocompatibility with epidermal cells were assessed in vitro. Finally, a full-thickness skin defect model was established to evaluate the therapeutic efficacy of the skin patch. RESULTS The EMSCs-CM contains abundant bioactive proteins including VEGF, KGF, EGF, bFGF, SHH, IL-10, and fibronectin. The bioactive functional composite skin patch containing EMSCs-CM lyophilized powder showed the network-like microstructure could continuously release the bioactive proteins, and possessed ideal biocompatibility with rat epidermal cells in vitro. Transplantation of the composite skin patch could expedite the healing of the full-thickness skin defect by promoting endogenous epidermal stem cell proliferation and skin appendage regeneration in rats. CONCLUSION In summary, the bioactive functional composite skin patch containing EMSCs-CM lyophilized powder can effectively accelerate skin repair, which has promising application prospects in the treatment of skin defects.

Abstract
The main strategy of cancer cells for survival is uncontrolled cell division and escape from apoptosis. The use of anticancer agents inducing the production of reactive oxygen species (ROS) and controlling cell division might be a therapeutic approach to eradicate cancer cells. Herein, we examined the therapeutic effects of Auraptene on CT26 cells as well as on a mouse model of colorectal cancer (CRC). The spheroid assay was also conducted to analyze the anti-proliferative activity of Auraptene. We also assessed the in vitro analysis of ROS generation. The impact of Auraptene on oxidant/antioxidant markers, as well as the mRNA expression of Bax, Bcl-2, Nrf2, Cyclin D1, and Survivin genes, was evaluated by qPCR in tumor samples. As a result, Auraptene significantly reduced the size of CT26 spheroids at a dose of 200 µM. After 12 h, ROS levels were significantly elevated in CT26 cells. The administration of Auraptene induced apoptosis and the cell cycle arrest by modulating Bax, Bcl-2, Nrf2, Cyclin D1, and Survivin mRNA levels. Furthermore, our results demonstrated that Auraptene suppressed CAT, GSH (reduced Glutathione), and FRAP while increasing MDA in tissue homogenates which in turn could raise oxidative stress and stimulate apoptosis. Therefore, Auraptene may act as a powerful adjuvant therapy in CRC since it triggers apoptosis and cell cycle.

Abstract
The three-dimensional multicellular spheroid (3D MCS) model has been employed in cholangiocarcinoma research as it generates 3D architecture and includes more physiological relevance with the multicellular arrangement. However, it is also essential to explain the molecular signature in this microenvironment and its structural complexity. The results indicated that poorly differentiated CCA cell lines were unable to form 3D MCS due to the lack of cell adhesion molecules with more mesenchymal marker expression. The well-differentiated CCA and cholangiocyte cell lines were able to develop 3D MCSs with round shapes, smooth perimeter, and cell adhesion molecules that led to the hypoxic and oxidative microenvironment detected. For MMNK-1, KKU-213C, and KKU-213A MCSs, the proteo-metabolomic analysis showed proteins and metabolic products altered compared to 2D cultures, including cell-cell adhesion molecules, energy metabolism-related enzymes and metabolites, and oxidative-related metabolites. Therefore, the 3D MCSs provide different physiological states with different phenotypic signatures compared to 2D cultures. Considering the 3D model mimics more physiological relevance, it might lead to an alternate biochemical pathway, targeting to improve drug sensitivity for CCA treatment.

Abstract
BACKGROUND Human mesenchymal stem cells are being used for various regenerative applications in past decades. This study chronicled a temporal profile of the transcriptional pattern and promoter methylation status of the osteogenic related gene in dental pulp stem cells (DPSCs) derived from 3-dimensional spheroid culture (3D) vis a vis 2-dimensional (2D) monolayer culture upon osteogenic induction. METHODS Biomimetic properties of osteogenesis were determined by alkaline phosphatase assay and alizarin red staining. Gene expression and promoter methylation status of osteogenic genes such as runt-related transcription factor-2, collagen1α1, osteocalcin (OCN), and DLX5 (distal-homeobox) were performed by qPCR assay and bisulfite sequencing, respectively. Furthermore, µ-Computed tomography (micro-CT) was performed to examine the new bone formation in critical-sized rat calvarial bone defect model. RESULTS Our results indicated a greater inclination of spheroid culture-derived DPSCs toward osteogenic lineage than the monolayer culture. The bisulfite sequencing of the promoter region of osteogenic genes revealed sustenance of low methylation levels in DPSCs during the progression of osteogenic differentiation. However, the significant difference in the methylation pattern between 2D and 3D derived DPSCs were identified only for OCN gene promoter. We observed differences in the mRNA expression pattern of epigenetic writers such as DNA methyltransferases (DNMTs) and methyl-cytosine dioxygenases (TET) between the two culture conditions. Further, the DPSC spheroids showed enhanced new bone formation ability in an animal model of bone defect compared to the cells cultivated in a 2D platform which further substantiated our in-vitro observations. CONCLUSION The distinct cellular microenvironment induced changes in DNA methylation pattern and expression of epigenetic regulators such as DNMTs and TETs genes may lead to increase expression of osteogenic markers in 3D spheroid culture of DPSCs which make DPSCs spheroids suitable for osteogenic regeneration compared to monolayers.

Different Expression of Thyroid-Specific Proteins in Thyroid Cancer Cells between 2-Dimensional (2D) and 3-Dimensional (3D) Culture Environment. Cells 2022; 11:cells11223559.

Abstract
The two-dimensional (2D) monolayer culture as a conventional method has been widely applied in molecular biology fields, but it has limited capability to recapitulate real cell environments, being prone to misinterpretation with poor prediction of in vivo behavior. Recently, the three-dimensional (3D) spheroid culture has been studied extensively. Spheroids are self-assembled cell aggregates that have biomimicry capabilities. The behavior of thyroid cancer under the 3D spheroid culture environment has been studied; however, there are no reports regarding differences in the degree of thyroid cancer cell differentiation under 2D and 3D culture conditions. This study investigated the expression of thyroid differentiation proteins related to iodide-metabolizing mechanisms in thyroid cancer cells under different culture conditions. Four thyroid cancer cell lines and one thyroid follicular epithelial cell line were grown in adherent 2D cell culture and 3D spheroid culture with agarose-coated plates. We observed changes in proliferation, hypoxia, extracellular matrix (ECM), cytoskeleton, thyroid-specific proteins, and thyroid transcription factors. All cell lines were successfully established in the spheroid following cell aggregation. Proliferation considerably decreased, while hypoxia-inducible factor 1-α(HIF1-α) was promoted in 3D spheroids; moreover, 3D spheroids with thyroid cancers showed diminished thyroid differentiation markers, but thyroid follicular epithelial cells revealed either a maintenance or weak decline of protein expression. We verified that the 3D spheroid culture environment can be similar to in vivo conditions because of its alterations in numerous cellular and functional activities, including morphology, cellular proliferation, viability, hypoxia, ECM, cytoskeleton, and thyroid differentiation, compared to the conventional 2D monolayer culture environment. An in vitro experimental study using 3D spheroid culture is ideal for the faster discovery of new drugs.

Tabibzadeh S. Repair, regeneration and rejuvenation require un-entangling pluripotency from senescence. Ageing Res Rev 2022; 80:101663. [PMID: 35690382 DOI: 10.1016/j.arr.2022.101663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 05/27/2022] [Accepted: 06/04/2022] [Indexed: 11/16/2022]
Abstract
There is a notion that pluripotency and senescence, represent two extremes of life of cells. Pluripotent cells display epigenetic youth, unlimited proliferative capacity and pluripotent differentiating potential whereas cells that reach the Hayflick limit, transit to senescence, undergo permanent inhibition of cell replication and create an aging tissue landscape. However, pluripotency and senescence appear to be intimately linked and are jointly generated in many different contexts such as during embryogenesis or formation of tissue spheroids, in stem cell niches, cancer, or by induction of a pluripotent state (induced pluripotency). Tissue damage and senescence provide signals that are critical to generation of a pluripotent state and, in turn, pluripotency, induces senescence. Thus, it follows, that precisely timed control of senescence is required for harnessing the full benefits of both senescence and its associated pluripotency during tissue regeneration or rejuvenation.

Morsczeck C. Mechanisms during Osteogenic Differentiation in Human Dental Follicle Cells. Int J Mol Sci 2022; 23:ijms23115945. [PMID: 35682637 PMCID: PMC9180518 DOI: 10.3390/ijms23115945] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 05/19/2022] [Accepted: 05/23/2022] [Indexed: 12/22/2022] Open
Abstract
Human dental follicle cells (DFCs) as periodontal progenitor cells are used for studies and research in regenerative medicine and not only in dentistry. Even if innovative regenerative therapies in medicine are often considered the main research area for dental stem cells, these cells are also very useful in basic research and here, for example, for the elucidation of molecular processes in the differentiation into mineralizing cells. This article summarizes the molecular mechanisms driving osteogenic differentiation of DFCs. The positive feedback loop of bone morphogenetic protein (BMP) 2 and homeobox protein DLX3 and a signaling pathway associated with protein kinase B (AKT) and protein kinase C (PKC) are presented and further insights related to other signaling pathways such as the WNT signaling pathway are explained. Subsequently, some works are presented that have investigated epigenetic modifications and non-coding ncRNAs and their connection with the osteogenic differentiation of DFCs. In addition, studies are presented that have shown the influence of extracellular matrix molecules or fundamental biological processes such as cellular senescence on osteogenic differentiation. The putative role of factors associated with inflammatory processes, such as interleukin 8, in osteogenic differentiation is also briefly discussed. This article summarizes the most important insights into the mechanisms of osteogenic differentiation in DFCs and is intended to be a small help in the direction of new research projects in this area.

Effect of Photobiomodulation Therapy on Differentiation of Mesenchymal Stem Cells Derived from Impacted Third Molar Tooth into Neuron-like Cells. Photochem Photobiol 2022; 98:1434-1440. [PMID: 35363889 DOI: 10.1111/php.13627] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 03/28/2022] [Indexed: 11/29/2022]
Abstract
Peripheral nerve damages are among the most important consequences of dental and maxillofacial procedures. Tissue engineering using mesenchymal stem cells (MSCs) is a promising method to manage such injuries. Moreover, photobiomodulation therapy (PBMT) can enhance this treatment. The present study aimed to investigate the effect of PBMT on differentiation of MSCs derived from dental follicle (DF) into neurons. MSCs were isolated from an impacted tooth follicle by digestion method. The stem cells were cultured, and differentiated into neurons. The cells received two sessions of PBMT with 810 or 980nm diode laser (100 mW, 4 J/cm2 ) in either DMEM or neural inductive medium . Phenotypic characterization of the cells was determined using Flow cytometry. In addition, β-tubulin and MAP2 genes expression level changes were analyzed using RT-PCR and western blot technique. After 14 days, Flow cytometry analysis confirmed the mesenchymal nature of cells. RT-PCR and western blot affirmed the expression of β-tubulin and MAP2 genes and proteins, respectively. PBMT with both wavelengths significantly increased β-tubulin and MAP2 expression in neural inductive medium with highest expression mean in 980-nm group. PBMT with 810 and 980-nm lasers could be a promising adjunctive method in differentiation of DF-originated MSCs into neural cells.
