Multiomics analysis of cultured mouse periodontal ligament cell-derived extracellular matrix. Sci Rep 2024; 14:354. [PMID: 38172274 PMCID: PMC10764881 DOI: 10.1038/s41598-023-51054-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Accepted: 12/29/2023] [Indexed: 01/05/2024] Open
Abstract
A comprehensive understanding of the extracellular matrix (ECM) is essential for developing biomimetic ECM scaffolds for tissue regeneration. As the periodontal ligament cell (PDLC)-derived ECM has shown potential for periodontal tissue regeneration, it is vital to gain a deeper understanding of its comprehensive profile. Although the PDLC-derived ECM exhibits extracellular environment similar to that of periodontal ligament (PDL) tissue, details of its molecular composition are lacking. Thus, using a multiomics approach, we systematically analyzed cultured mouse PDLC-derived ECM and compared it to mouse PDL tissue as a reference. Proteomic analysis revealed that, compared to PDL tissue, the cultured PDLC-derived ECM had a lower proportion of fibrillar collagens with increased levels of glycoprotein, corresponding to an immature ECM status. The gene expression signature was maintained in cultured PDLCs and was similar to that in cells from PDL tissues, with additional characteristics representative of naturally occurring progenitor cells. A combination of proteomic and transcriptomic analyses revealed that the cultured mouse PDLC-derived ECM has multiple advantages in tissue regeneration, providing an extracellular environment that closely mimics the environment in the native PDL tissue. These findings provide valuable insights for understanding PDLC-derived ECM and should contribute to the development of biomimetic ECM scaffolds for reliable periodontal tissue regeneration.

calvarial bone defect reconstruction: An adipose
tissue‐based
developmental engineering approach. Bioeng Transl Med 2022; 7:e10312. [PMID: 36176620 PMCID: PMC9472001 DOI: 10.1002/btm2.10312] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Revised: 02/17/2022] [Accepted: 03/04/2022] [Indexed: 02/05/2023] Open
Abstract
Developmental engineering of living implants from different cell sources capable of stimulating bone regeneration by recapitulating endochondral ossification (ECO) is a promising strategy for large bone defect reconstruction. However, the clinical translation of these cell‐based approaches is hampered by complex manufacturing procedures, poor cell differentiation potential, and limited predictive in vivo performance. We developed an adipose tissue‐based developmental engineering approach to overcome these hurdles using hypertrophic cartilaginous (HyC) constructs engineered from lipoaspirate to repair large bone defects. The engineered HyC constructs were implanted into 4‐mm calvarial defects in nude rats and compared with decellularized bone matrix (DBM) grafts. The DBM grafts induced neo‐bone formation via the recruitment of host cells, while the HyC pellets supported bone regeneration via ECO, as evidenced by the presence of remaining cartilage analog and human NuMA‐positive cells within the newly formed bone. However, the HyC pellets clearly showed superior regenerative capacity compared with that of the DBM grafts, yielding more new bone formation, higher blood vessel density, and better integration with adjacent native bone. We speculate that this effect arises from vascular endothelial growth factor and bone morphogenetic protein‐2 secretion and mineral deposition in the HyC pellets before implantation, promoting increased vascularization and bone formation upon implantation. The results of this study demonstrate that adipose‐derived HyC constructs can effectively heal large bone defects and present a translatable therapeutic option for bone defect repair.

Abstract
Different approaches to develop engineered scaffolds for periodontal tissues regeneration have been proposed. In this review, innovations in stem cell technology and scaffolds engineering focused primarily on Periodontal Ligament (PDL) regeneration are discussed and analyzed based on results from pre-clinical in vivo studies and clinical trials. Most of those developments include the use of polymeric materials with different patterning and surface nanotopography and printing of complex and sophisticated multiphasic composite scaffolds with different compartments to accomodate for the different periodontal tissues' architecture. Despite the increased effort in producing these scaffolds and their undoubtable efficiency to guide and support tissue regeneration, appropriate source of cells is also needed to provide new tissue formation and various biological and mechanochemical cues from the Extraccellular Matrix (ECM) to provide biophysical stimuli for cell growth and differentiation. Cell sheet engineering is a novel promising technique that allows obtaining cells in a sheet format while preserving ECM components. The right combination of those factors has not been discovered yet and efforts are still needed to ameliorate regenerative outcomes towards the functional organisation of the developed tissues.

Abstract
Numerous treatment methods have been developed to modify the surface of dental implants to improve cell migration and proliferation, removal torque, and osseointegration. Recent studies have constructed cell sheet-implant complexes with enhanced osteogenic capabilities. However, these complexes have some limitations, such as requirements for complex preparation processes, cell vitality maintenance, strict preservation conditions, and the induction of immunogenicity. Extracellular matrix (ECM) sheets without cells may be a more desirable material. To date, the effect of ECM sheets on implant osseointegration has not been reported. In this study, we fabricated ECM sheet-implant complexes through the combination of rat bone marrow mesenchymal stem cell (BMSC)-derived ECM sheets with sandblasted, large-grit, acid-etched (SLA) implants. These complexes were characterized by light microscopy, scanning electron microscopy (SEM), and immunofluorescence (IF) assays. The adhesion, proliferation, and osteogenic differentiation of BMSCs cultured on ECM sheets were detected in vitro. Then, the ECM sheet-implant complexes were transplanted into the metaphysis of the tibias of rats to evaluate the implant osseointegration in vivo. The results showed that ECM sheets were successfully constructed and showed significantly improved adhesion and proliferation. BMSCs cultured on ECM sheets upregulated the expression levels of the osteogenic-related genes alkaline phosphatase (ALP), bone morphogenetic protein 2 (BMP2), and runt-related transcription factor 2 (Runx2) compared to controls. In vivo, ECM sheet-implant complexes demonstrated superior new bone formation. Our findings proved that the BMSC-derived ECM sheets promoted osseointegration in vitro and in vivo. The current study indicated that the ECM sheet could be an ideal tissue engineering material, and ECM sheet-implant complexes could provide a strategy with low immunogenicity and easy storage and transportation. This research provides a novel strategy for the development of implant surface modification approaches.

Abstract
Periodontal ligament stem cells (PDLSCs), as potential "seed cells" for periodontal tissue repair and regeneration, require to be expanded in vitro for a large scale. Senescence of PDLSCs occurred during long-term culture may compromise the therapeutic effects of PDLSCs. Medium supplements may be useful in antisenescence. However, the effects and mechanisms of vitamin C (Vc) treatment on PDLSCs during long-term culture are still unclear. In this study, we identified that Vc-treated PDLSCs cells maintained a slender morphology, higher growth rate and migration capacity, stemness, and osteogenic differentiation capability during a long-term culture. Moreover, we also identified that Notch3 was significantly upregulated during the cell senescence, and Vc treatment alleviated the senescence of PDLSCs through inhibition of Notch3 during long-term culture. In summary, Vc treatment suppressed PDLSCs senescence by reducing the expression of Notch3 and might be a simple and useful strategy to inhibit cellular senescence during the cell long-term culture.

Abstract
OBJECTIVE Colorectal cancer (CRC) is the 3rd most common cancer worldwide. Recently, long non-coding RNAs (lncRNAs) were found to be critical modulators in the CRC progression. The aim of this study is to investigate the potential roles of lncRNA P73 antisense RNA 1T (TP73-AS1) in CRC development and progression. METHODS Quantitative real-time PCR (qRT-PCR) was performed to determine relevant gene expression levels; western blot was performed to determine protein expression levels; CCK-8, colony formation, wound healing and Transwell invasion assays were used to determined CRC cell proliferation, migration and invasion; in vivo tumor growth was assessed in xenograft mice model. RESULTS TP73-AS1 was up-regulated in both CRC tissues and CRC cell lines. Overexpression of TP73-AS1 was associated with metastasis and advanced clinical stages in CRC patients. Overexpression of TP73-AS1 promoted CRC cell growth, proliferation, migration and invasion in vitro; and knockdown of TP73-AS1 significantly inhibited CRC cell growth, proliferation, migration and invasion in vitro as well as tumor growth in vivo. Bioinformatics analysis and luciferase reporter assay indicated that TP73-AS1 could bind directly with miR-194, and TP73-AS1 negatively regulated the expression of miR-194 in CRC cells. Further study indicated that miR-194 negatively regulated the downstream target of transforming growth factor alpha (TGFα) via targeting its 3' untranslated region, and TP73-AS1 positively regulated the expression of TGFα in CRC cells. Moreover, overexpression of miR-194 suppressed CRC cell proliferation and invasion, and attenuated the effects of TP73-AS1 overexpression on CRC cell proliferation and invasion. Silence of TGFα inhibited CRC cell proliferation and invasion, and also reversed the effects of TP73-AS1 overexpression on CRC cell proliferation and invasion. CONCLUSIONS this study demonstrated that TP73-AS1 regulated CRC progression by acting as a competitive endogenous RNA to sponge miR-194 to modulate the expression of TGFα.

Abstract
As the theory of cancer stem cells (CSCs) is maturing, CSC-targeted therapy is emerging as an important therapeutic strategy and seeking the ideal method for rapid enrichment and purification of CSCs has become crucial. So far, based on the known CSC phenotypes and biological characteristics, the methods for enrichment CSCs mainly include low adhesion culture, low oxygen culture, chemotherapy drug stimulation and side population (SP) sorting but these methods cannot realize quick enrichment of the desired CSCs. Herein, we adopt a novel method that efficiently enriches a certain amount of CSCs through agarose multi-well dishes using rubber micro-molds to make cancer cells into cell spheroids (3D). These 3D cancer cell spheroids in the proportions of expression of CSC biomarkers (single stain of CD44, CD44v6 and CD133 or double stain of both CD44 and CD133) were significantly higher than those of the conventional adherent culture (2D) using flow cytometry analysis. In addition, the expression levels of stemness transcription factors such as OCT4, NANOG and SOX2 in 3D were also significantly higher than that in 2D through Western blot (WB) and quantitative polymerase chain reaction (qPCR) assays. In addition, the CSCs in 3D could form colonies with different sizes in soft agar. In conclusion, we developed a new method to enrich some kinds of CSCs, which might be a benefit for future CSC-targeted therapy studies and anti-CSC drug screening applications.

Abstract
Periodontal disease is a widespread disease, which without proper treatment, may lead to tooth loss in adults. Because stem cells from the inflammatory microenvironment created by periodontal disease exhibit impaired regeneration potential even under favorable conditions, it is difficult to obtain satisfactory therapeutic outcomes using traditional treatments, which only focus on the control of inflammation. Therefore, a new stem cell-based therapy known as cell aggregates/cell sheets technology has emerged. This approach provides sufficient numbers of stem cells with high viability for treating the defective site and offers new hope in the field of periodontal regeneration. However, it is not sufficient for regenerating periodontal tissues by delivering cell aggregates/cell sheets to the impaired microenvironment in order to suppress the function of resident cells. In the present review, we summarize some promising bioactive molecules that act as cellular signals, which recreate a favorable microenvironment for tissue regeneration, recruit endogenous cells into the defective site and enhance the viability of exogenous cells.
