Abstract
This study aimed to assess effects of 3-dimensionally (3D) printed poly-d,l-lactin (PDLLA) on human alveolar bone-derived mesenchymal stem cell (h-ABMSC) osteogenic proliferation and differentiation. Human ABMSCs were cultured and identified using flow cytometry and morphological analysis. Control and PDLLA experimental groups were assessed using a Cell Counting Kit-8 (CCK-8) to detect cellular cytotoxicity and proliferative activity. Real-time quantitative polymerase chain reaction was used to determine expression levels of osteogenesis genes including alkaline phosphatase (ALP), Runt-related transcription factor 2 (Runx-2), osteopontin (OPN), and osteocalcin (OCN). The results showed that h-ABMSCs were successfully cultured and revealed by microscopic observation. Human ABMSCs were spindle-shaped, with clustered and fish-like primary cells. Cell surface markers were negative for CD34 and positive for CD44 and CD90. PDLLA had no cytotoxicity. Human ABMSCs proliferated normally, and osteogenic differentiation of the cells was observed on the surface of PDLLA. Cellular proliferative activity and expression levels of osteogenesis-related genes of PDLLA and control groups showed no significant difference, including ALP, Runx-2, OPN, and OCN. These results suggest that 3D-printed PDLLA has good cell compatibility and biological activity.

Shi P, Zhou W, Dong J, Li S, Lv P, Liu C. Scaffolds of bioactive glass (Bioglass®) combined with recombinant human bone morphogenetic protein -9 (rhBMP-9) for tooth extraction site preservation. Heliyon 2022; 8:e08796. [PMID: 35097232 PMCID: PMC8783125 DOI: 10.1016/j.heliyon.2022.e08796] [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: 04/11/2021] [Revised: 08/08/2021] [Accepted: 01/13/2022] [Indexed: 12/23/2022] Open
Abstract
Objective The study aimed to investigate the osteogenic ability of bioactive glass (bioglass) combined with recombinant human bone morphogenetic protein-9 (rhBMP-9) on rat bone marrow mesenchymal stem cells (BMSCs) in vitro. The study also compares bone regeneration using rhBMP9 soaked with different carrier systems, including bioglass or collagen membranes (BioGide, BG) in a rat alveolar bone site preservation model in vivo. Methods Scanning electron microscopy was employed to analyze bioglass surface. The absorption and release potential of rhBMP9 from bioglass were researched by ELISA. The cell viability, adhesion, proliferation, and differentiation were assessed for rhBMP9 soaked on bioglass by cck-8 kit, alkaline phosphatase (ALP) activity assay, alizarin red staining, and real-time PCR. Furthermore, prepared grafts (bioglass + BG, bioglass/rhBMP9+BG, and bioglass + BG/rhBMP9) were implanted into the maxillary right first incisor sockets of Sprague Dawley rats for 8 weeks, and new bone formation was quantified by micro-CT and histological analysis. Results Bioglass absorbed rhBMP9 dramatically and released it with a slow and stable speed within ten days by ELISA. When used with cck-8 kit detection, cell viability at 24 h, cell adhesion rate at 8 h, and cell proliferation at 1, 3, and 5 days were decreased in the bioglass alone group versus the control group but slightly increased with the addition of rhBMP9. Similarly, the effect of osteogenic differentiation on bioglass increased significantly when combined with rhBMP9 by upregulating the expression of ALP, mineralized matrix, and osteogenic related genes. Furthermore, both bioglass/rhBMP9+BG samples and bioglass + BG/rhBMP9 samples significantly improved several bone formation parameters compared with bioglass + BG samples. Interestingly, bioglass + BG/rhBMP9 samples demonstrated more bone regeneration in rat site preservation models. Conclusions Both bioglass and BG can be applied in GBR surgery as effective carriers of rhBMP9. However, BG may be more suitable than bioglass for investigating site preservation effect after tooth extraction when associated with rhBMP9 and provides a practical clinical solution to the problem of bone deficiency caused by alveolar bone atrophy.

[PMID: 34055053 PMCID: PMC8138271 DOI: 10.3892/etm.2021.10168] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Accepted: 03/19/2021] [Indexed: 12/22/2022] Open
Abstract
Bcl-xL is a transmembrane molecule in the mitochondria, with apoptosis-related and pro-metabolic functions, that also plays a role in chondrogenesis and differentiation. A Bcl-xL mutant, in which the GRI sequence is replaced by ELN, has no anti-apoptotic effect, while other biological functions of this mutant remain unchanged. The present study investigated the impact of this Bcl-xL mutant on cartilage differentiation and the expression levels of TGF-β and bone morphogenetic protein (BMP). Human bone marrow mesenchymal stem cells (BMSCs) were transfected with Bcl-xL and Bcl-xL mutant (∆Bcl-xL) overexpression vectors. The cells were divided into four groups: Control (not subjected to any transfection), EV (empty pcDNA3.1-Bcl-xL vector), OV (Bcl-xL overexpression) and ∆OV (∆Bcl-xL overexpression). Saffron and toluidine blue staining was performed to observe cartilage tissue formation. Flow cytometry was conducted to measure BMSC apoptosis. The expression levels of TGF-β and BMP were evaluated using reverse transcription-quantitative PCR (RT-qPCR) and western blotting. Compared with that in the control group, the expression levels of Bcl-xL in the OV group increased significantly (P<0.05). Western blotting and RT-qPCR results revealed that OV and ∆OV treatment increased the expression levels of TGF-β and BMP in transfected cells, compared to their expression in the control and EV groups (P<0.05). Saffron and toluidine blue staining results showed that cartilage formation was increased in the ∆OV and ∆OV + Bax-/Bak-groups to similar degrees. Cell apoptosis in the ∆OV group did not change compared with that in the control group. The Bcl-xL mutant promoted cartilage differentiation of BMSCs and upregulated TGF-β/BMP expression. This enhancement of chondrogenic differentiation was not related to the expression of Bax and Bak. Taken together, these findings provided for improved application of bone tissue engineering technology in the treatment of articular cartilage defects.

Periodontal Tissues, Maxillary Jaw Bone, and Tooth Regeneration Approaches: From Animal Models Analyses to Clinical Applications. NANOMATERIALS (BASEL, SWITZERLAND) 2018; 8:E337. [PMID: 29772691 PMCID: PMC5977351 DOI: 10.3390/nano8050337] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/24/2018] [Revised: 05/14/2018] [Accepted: 05/15/2018] [Indexed: 12/13/2022]
Abstract
This review encompasses different pre-clinical bioengineering approaches for periodontal tissues, maxillary jaw bone, and the entire tooth. Moreover, it sheds light on their potential clinical therapeutic applications in the field of regenerative medicine. Herein, the electrospinning method for the synthesis of polycaprolactone (PCL) membranes, that are capable of mimicking the extracellular matrix (ECM), has been described. Furthermore, their functionalization with cyclosporine A (CsA), bone morphogenetic protein-2 (BMP-2), or anti-inflammatory drugs' nanoreservoirs has been demonstrated to induce a localized and targeted action of these molecules after implantation in the maxillary jaw bone. Firstly, periodontal wound healing has been studied in an induced periodontal lesion in mice using an ibuprofen-functionalized PCL membrane. Thereafter, the kinetics of maxillary bone regeneration in a pre-clinical mouse model of surgical bone lesion treated with BMP-2 or BMP-2/Ibuprofen functionalized PCL membranes have been analyzed by histology, immunology, and micro-computed tomography (micro-CT). Furthermore, the achievement of innervation in bioengineered teeth has also been demonstrated after the co-implantation of cultured dental cell reassociations with a trigeminal ganglia (TG) and the cyclosporine A (CsA)-loaded poly(lactic-co-glycolic acid) (PLGA) scaffold in the jaw bone. The prospective clinical applications of these different tissue engineering approaches could be instrumental in the treatment of various periodontal diseases, congenital dental or cranio-facial bone anomalies, and post-surgical complications.
