Background. Evaluation of any material that is utilised for clinical applications is essential in order to ensure that it acquires physical, mechanical and biocompatible properties required for its proposed function. Understanding of the conditions that regulate the mechanical and physical characteristics of a material particularly biopolymers is crucial in the field of cell and tissue engineering. The aim of this work is to assemble some polymers and crosslink with each other using β-glycerophosphate to produce a scaffolding which is suitable for in vitro tissue regeneration.Materials and methods. The experimental procedures in this project involved the culturing of cells in different suspensions containing control, CSG hydrogel, fibronectin, and hydrogel with fibronectin. The aim of the conducted experiment was to find the cell viability and cytotoxicity analysis of CSG hydrogel, and to study how the cells interact with CSG hydrogel as a possible candidate for articular cartilage repair. Another aim of this work was to find out whether the cells can grow and survive in CSG hydrogel for a period of 24 hours. Results and conclusions. The results obtained from series of tests proved that CSG3 has the most optimum properties, as it presented the highest viscosity at 37°C, the highest stability during temperature changes, and an enhanced elastic behaviour at the physiological temperature.

Horses are widely used as large animal preclinical models for cartilage repair studies, and hence, there is an interest in using equine synovial fluid-derived mesenchymal stem cells (SFMSCs) in research and clinical applications. Since, we have previously reported that similar to bone marrow-derived MSCs (BMMSCs), SFMSCs may also exhibit donor-to-donor variations in their stem cell properties; the current study was carried out as a proof-of-concept study, to compare the in vivo potential of equine BMMSCs and SFMSCs in articular cartilage repair. MSCs from these two sources were isolated from the same equine donor. In vitro analyses confirmed a significant increase in COMP expression in SFMSCs at day 14. The cells were then encapsulated in neutral agarose scaffold constructs and were implanted into two mm diameter full-thickness articular cartilage defect in trochlear grooves of the rat femur. MSCs were fluorescently labeled, and one week after treatment, the knee joints were evaluated for the presence of MSCs to the injured site and at 12 weeks were evaluated macroscopically, histologically, and then by immunofluorescence for healing of the defect. The macroscopic and histological evaluations showed better healing of the articular cartilage in the MSCs’ treated knee than in the control. Interestingly, SFMSC-treated knees showed a significantly higher Col II expression, suggesting the presence of hyaline cartilage in the healed defect. Data suggests that equine SFMSCs may be a viable option for treating osteochondral defects; however, their stem cell properties require prior testing before application.

Abstract Background Given the limited regenerative capacity of injured articular cartilage, the absence of suitable therapeutic options has encouraged tissue-engineering approaches for its regeneration or replacement. Sources of data Published articles in any language identified in PubMed and Scopus electronic databases up to August 2019 about the in vitro and in vivo properties of cartilage engineered constructs. A total of 64 articles were included following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Areas of agreement Regenerated cartilage lacks the biomechanical and biological properties of native articular cartilage. Areas of controversy There are many different approaches about the development of the architecture and the composition of the scaffolds. Growing points Novel tissue engineering strategies focus on the development of cartilaginous biomimetic materials able to repair cartilage lesions in association to cell, trophic factors and gene therapies. Areas timely for developing research A multi-layer design and a zonal organization of the constructs may lead to achieve cartilage regeneration.

The histological features of cartilage call attention to the fact that cartilage has a little capacity to repair itself owing to the lack of a blood supply, nerves, or lymphangion. Stem cells have emerged as a promising option in the field of cartilage tissue engineering and regenerative medicine and could lead to cartilage repair. Much research has examined cartilage regeneration utilizing stem cells. However, both the potential and the limitations of this procedure remain controversial. This review presents a summary of emerging trends with regard to using stem cells in cartilage tissue engineering and regenerative medicine. In particular, it focuses on the characterization of cartilage stem cells, the chondrogenic differentiation of stem cells, and the various strategies and approaches involving stem cells that have been used in cartilage repair and clinical studies. Based on the research into chondrocyte and stem cell technologies, this review discusses the damage and repair of cartilage and the clinical application of stem cells, with a view to increasing our systematic understanding of the application of stem cells in cartilage regeneration; additionally, several advanced strategies for cartilage repair are discussed.

Introduction: In Islamic practice, the use of Qur’anic recitation in treatment can be traced back to the times of Prophet Muhammad (PBUH). This preliminary study aims to identify the potential of Qur’anic recitation of Surah Al-Fatihah on the proliferation of chondrocytes derived from rabbit articular cartilage. Cartilage tissue engineering offers an alternative way to facilitate cartilage regeneration in-vitro. Materials and Methods: The cellular model was established using a serially cultured and expanded chondrocytes in-vitro. The model was assigned into three groups. The first group was exposed to the Surah Al-Fatihah, recited 17 times based on the five times daily prayer unit (Raka’ah) obligated upon Muslims. The second group was exposed to an Arabic poem recitation. The third group was not exposed to any sound and served as the control. All groups were subjected to the growth profile analysis. The analysis was conducted at different passages starting from passage 0 to passage 3. Results: The results showed that the cells proliferation based on the growth kinetic analysis is higher for the cells exposed with Qur’anic recitation as compared to the Arabic poem and control groups. Conclusions: The proliferation process of the rabbit articular cartilage might be influenced with the use of Qur’anic recitation and as well as Arabic poem recitation. Exposure to the Western poem recitation and mute sound will be added for future study. It is hoped that this study could shed some light on the potential use of the Qur’anic recitation to facilitate cartilage regeneration in tissue engineering studies.

This chapter reviews the structure and function of articular cartilage and the pathogenesis of Osteoarthritis (OA) before exploring the challenges associated with cartilage repair and regeneration. Surgical techniques for cartilage repair are critically reviewed and special emphasis is placed upon arthroscopic lavage and debridement, microfracture, bone marrow stimulation, and autologous osteochondral allografting. Biomimetic models of cartilage relevant to cartilage regeneration and tissue engineering research are reviewed along with microenvironmental approaches that preserve the chondrocyte phenotype using a combination of biomimetic 3-dimensional cell culture systems and growth factor supplementation. Future refinement of tissue-engineering approaches for cartilage repair will benefit significantly from advances in cell-based repair strategies. The authors provide their own perspectives by highlighting and prioritizing areas for future investigation.

Mesenchymal stromal cells (MSCs) have shown a high potential for cartilage repair. Collagen-based scaffolds are used to deliver and retain cells at the site of cartilage damage. The aim of the work was a comparative analysis of the capacity of the MSCs from human adipose tissue to differentiate into chondrocytes in vitro and to stimulate the regeneration of articular cartilage in an experimental model of rabbit knee osteoarthrosis when cultured on microheterogenic collagen-based hydrogel (MCH) and the microparticles of decellularized porcine articular cartilage (DPC). The morphology of samples was evaluated using scanning electron microscopy and histological staining methods. On the surface of the DPC, the cells were distributed more uniformly than on the MCH surface. On day 28, the cells cultured on the DPC produced glycosaminoglycans more intensely compared to the MCH with the synthesis of collagen type II. However, in the experimental model of osteoarthrosis, the stimulation of the cartilage regeneration was more effective when the MSCs were administered to the MCH carrier. The present study demonstrates the way to regulate the action of the MSCs in the area of cartilage regeneration: the MCH is more conducive to stimulating cartilage repair by the MSCs, while the DPC is an inducer for a formation of a cartilage-like tissue by the MSCs in vitro.

AbstractArticular cartilage is susceptible to damage but hard to self-repair due to its avascular nature. Traditional treatment methods are not able to produce satisfactory effects. Mesenchymal stem cells (MSCs) have shown great promise in cartilage repair. However, the therapeutic effect of MSCs is often unstable partly due to their heterogeneity. Understanding the heterogeneity of MSCs and the potential of different types of MSCs for cartilage regeneration will facilitate the selection of superior MSCs for treating cartilage damage. This review provides an overview of the heterogeneity of MSCs at the donor, tissue source and cell immunophenotype levels, including their cytological properties, such as their ability for proliferation, chondrogenic differentiation and immunoregulation, as well as their current applications in cartilage regeneration. This information will improve the precision of MSC-based therapeutic strategies, thus maximizing the efficiency of articular cartilage repair.

Here we reported a combined technique for articular cartilage repair, consisting of bone arrow mesenchymal stem cells (BMMSCs) and poly (dl-lactide-co-glycolide-b-ethylene glycol-b-dl-lactide-co-glycolide) (PLGA-PEG-PLGA) triblock copolymers carried with tissue growth factor (TGF-belat1). In the present study, BMMSCs seeded on PLGA-PEG-PLGA with were incubated in vitro, carried or not TGF-belta1, Then the effects of the composite on repair of cartilage defect were evaluated in rabbit knee joints in vivo. Full-thickness cartilage defects (diameter: 5 mm; depth: 3 mm) in the patellar groove were either left empty (n=18), implanted with BMMSCs/PLGA (n=18), TGF-belta1 modified BMMSCs/PLGA-PEG-PLGA. The defect area was examined grossly, histologically at 6, 24 weeks postoperatively. After implantation, the BMMSCs /PLGA-PEG-PLGA with TGF-belta1 group showed successful hyaline-like cartilage regeneration similar to normal cartilage, which was superior to the other groups using gross examination, qualitative and quantitative histology. These findings suggested that a combination of BMMSCs/PLGA-PEG-PLGA carried with tissue growth factor (TGF-belat1) may be an alternative treatment for large osteochondral defects in high loading sites.

Hydrogels are used as scaffolds for tissue engineering in vitro & in vivo because their three-dimensional network structure and viscoelasticity are similar to those of the macromolecular-based extracellular matrix (ECM) in living tissue. Especially, the synthetic hydrogels with controllable and reproducible properties were used as scaffolds to study the behaviors of cells in vitro and implanted test in vivo. In this review, two different structurally designed hydrogels, single-network (SN) hydrogels and double-network (DN) hydrogels, were used as scaffolds. The behavior of two cell types, anchorage-dependent cells and anchorage-independent cells, and the differentiation behaviors of embryoid bodies (EBs) were investigated on these hydrogels. Furthermore, the behavior of chondrocytes on DN hydrogels in vitro and the spontaneous cartilage regeneration induced by DN hydrogels in vivo was examined.
