Repair of cartilage defects associated with injury or pathology is a clinically relevant problem. Chondral tissue, especially articular cartilages, has a poor regenerative potential. Inflammation triggers the growth of connective tissue, which cannot exert the normal function of the hyaline cartilage. This contributes to the progression of the pathology and eventually raises the need for surgery. At present, there are no pharmaceutical drugs capable of restoring the damaged cartilage. However, advances in cell-based technology hold promise for regenerative medicine. Reports describing fabrication of autologous cartilage transplants pose a special interest. A registration dossier of a biomedical cell product must contain the product’s specifications, presenting the basic characteristics of the product that can be used to assess its quality. This review looks at a few basic parameters that can be used to verify the authenticity of the cell product derived from autologous chondrocytes and describe its specifications.

Investigation of the efficacy of collagen membranes used in the full-thickness hyaline cartilage defect surgery is extremely urgent from the point of view of everyday healthcare. However, there is no information about the collagen membrane transformation timeframe, patterns and type of tissue the membrane transforms into, nor on the quality of the newly formed cartilage, which hinders the use of collagen membranes in clinical practice. This study aimed to investigate the biological potential of collagen membranes and their capacity to transform into cartilage tissue. The study involved four pigs as subjects. We induced a full-thickness cartilage defect on their right hind limb joint and implanted an Ortokeep collagen membrane to remedy it. Two full-thickness cartilage defects were induced on the left hind limb joints of the animals, one was treated with an implanted Chondro-Gide collagen membrane, the other remained without a membrane. The animals were withdrawn from the experiment at 2, 3, 4, 6 months after the operation. This report contains results of the macroscopic and microscopic analyses revealing the character of cartilage tissue regeneration at various timepoints post-surgery. The collagen membranes proved to have a high biological potential and a capacity to transform into cartilage tissue. The cartilages were identifiable from the 3rd month of the study. Their thickness was growing significantly (p < 0.05) up to the 4th month post-surgery, gaining 18.7% in group 1 and 12.8% in group 2; afterwards, the formed tissue "matured". We have shown that the AMIC technique allows significant (p < 0.05) reduction of the bone tissue destruction area.

Migration Response

Strategies for cartilage tissue engineering and repair have recently focused on cell sources from the surrounding joint tissue as an alternative to chondrocytes. Synovium-derived stem cells (SDSCs) are found in the intimal layer of the synovium, the thin overlying capsule surrounding the joint space [1] and have been found to exhibit a greater chondrogenic potential than stem cells from other origins such as bone marrow stem cells or adipose derived stem cells [2–4]. Under directed cues, these cells have been shown to be capable of migrating from the synovium membrane into articular cartilage defects, though the mechanism behind such movement is unclear. As a first step, we have previously shown that SDSCs expanded in 2D monolayer culture in a growth factor cocktail of TGF-β1, FGF, and PDGF-ββ exhibit directed cathodal migration with perpendicular alignment when under the influence of an applied DC electric field [5]. As cellular behavior and response to an external stimulus can change with exposure to growth factors and passage number, we look here to characterize the effects of passaging on the migration response of SDSCs to an applied electric field. We hypothesize that if these cells develop more chondrocyte-like characteristics with growth factor passaging, their response will mimic that which has previously been reported for chondrocytes, notably directed cathodal (negative pole) migration and perpendicular realignment of the long axis to the direction of applied field [6].

Abstract Background Cartilage injury and pathological degeneration are reported in millions of patients globally. Cartilages such as articular hyaline cartilage are characterized by poor self-regeneration ability due to lack of vascular tissue. Current treatment methods adopt foreign cartilage analogue implants or microfracture surgery to accelerate tissue repair and regeneration. These methods are invasive and are associated with the formation of fibrocartilage, which warrants further exploration of new cartilage repair materials. The present study aims to develop an injectable modified gelatin hydrogel. Method The hydrogel effectively adsorbed proteoglycans secreted by chondrocytes adjacent to the cartilage tissue in situ, and rapidly formed suitable chondrocyte survival microenvironment modified by ε-poly-L-lysine (EPL). Besides, dynamic covalent bonds were introduced between glucose and phenylboronic acids (PBA). These bonds formed reversible covalent interactions between the cis−diol groups on polyols and the ionic boronate state of PBA. PBA-modified hydrogel induced significant stress relaxation, which improved chondrocyte viability and cartilage differentiation of stem cells. Further, we explored the ability of these hydrogels to promote chondrocyte viability and cartilage differentiation of stem cells through chemical and mechanical modifications. Results In vivo and in vitro results demonstrated that the hydrogels exhibited efficient biocompatibility. EPL and PBA modified GelMA hydrogel (Gel-EPL/B) showed stronger activity on chondrocytes compared to the GelMA control group. The Gel-EPL/B group induced the secretion of more extracellular matrix and improved the chondrogenic differentiation potential of stem cells. Finally, thus hydrogel promoted the tissue repair of cartilage defects. Conclusion Modified hydrogel is effective in cartilage tissue repair.

Social Significance

Degenerative pathology of the musculoskeletal system is one of the main reasons for decreased mobility in patients of the older age group. Increasing the life expectancy leads to predominance non-epidemic pathology in all developed countries. Therefore, degenerative diseases of musculoskeletal system have not only medical significance but also social significance. Objective is studying the morphological features of synovial environment of the decompensated osteoarthritic (OA) knee joint. Structural features of subchondral bone, hyaline cartilage of the femur and tibia, the articular capsule, menisci and ligamentous apparatus of the knee joint were studied in 64 patients who underwent total knee arthroplasty at the Department of Traumatology and Orthopedics Bashkirian State Medical University in the period from 2015 to 2020. Material selection, preparation of histological samples, staining with hematoxylin-eosin, microscopy was performed. Adaptive signs of articular cartilage of the femoral condyles manifest in the form of cartilage tissue rearrangement, which are most pronounced in the central zone of the cartilage. At the same time, the phenomena of decompensation and significant areas of destruction are noted. Also, the subchondral bone was replaced with connective tissue with subsequent sclerosis. This sclerosis subsequently led to the decompensation of structures of the hyaline cartilage in the deep and middle zones. Destructive and dystrophic processes were noted in the knee joint menisci. Articular cartilage was replaced with granulation tissue with subsequent invasion of blood vessels. Cruciate ligaments in patients with OA show signs of adaptation due to expansion of endothenonium layers between bundles of collagen fibers and an increase in the diameter of blood vessels.

Plga Microspheres

Repair of articular cartilage defects is a challenging aspect of clinical treatment. Kartogenin (KGN), a small molecular compound, can induce the differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) into chondrocytes. Here, we constructed a scaffold based on chondrocyte extracellular matrix (CECM) and poly(lactic-co-glycolic acid) (PLGA) microspheres (MP), which can slowly release KGN, thus enhancing its efficiency. Cell adhesion, live/dead staining, and CCK-8 results indicated that the PLGA(KGN)/CECM scaffold exhibited good biocompatibility. Histological staining and quantitative analysis demonstrated the ability of the PLGA(KGN)/CECM composite scaffold to promote the differentiation of BMSCs. Macroscopic observations, histological tests, and specific marker analysis showed that the regenerated tissues possessed characteristics similar to those of normal hyaline cartilage in a rabbit model. Use of the PLGA(KGN)/CECM scaffold may mimic the regenerative microenvironment, thereby promoting chondrogenic differentiation of BMSCs in vitro and in vivo. Therefore, this innovative composite scaffold may represent a promising approach for acellular cartilage tissue engineering.

Chondrocytes are used in cell-based therapies such as autologous chondrocyte implantation (ACI) and matrix-associated cartilage implantation (MACI). To transport the cartilage tissue to the laboratory for in vitro culturing, phosphate-buffered saline (PBS), Euro-Collins solution (ECS) and Dulbecco Modified Eagle Medium (DMEM) are commonly employed at 4-8 deg C. In this study, eight samples of human cartilage biopsy tissues from elderly patients with severe osteoarthritis undergoing arthroscopy, which would otherwise have been discarded, were used. The cartilage tissue samples were compared to assess the cell yield between two transportation groups: i) a thermo-reversible gelation polymer (TGP) based method without cool preservation (~25 deg C) and ii) ECS transport at 4 deg C. These samples were subjected to in vitro culture in a two-dimensional (2D) monolayer for two weeks and subsequently in a three-dimensional (3D) TGP scaffold for six weeks. The cell count obtained from the tissues transported in TGP was higher (0.2 million cells) than those transported in ECS (0.08 million cells) both after initial processing and after in vitro culturing for 2 weeks in 2D (18 million cells compared with 10 million cells). In addition, mRNA quantification demonstrated significantly higher expression of Col2a1 and SOX-9 in 3D-TGP cultured cells and lower expression of COL1a1 in RT-PCR, characteristic of the hyaline cartilage phenotype, than in 2D culture. This study confirms that the TGP cocktail is suitable for both the transport of human cartilage tissue and for in vitro culturing to yield better-quality cells for use in regenerative therapies.

The use of mesenchymal stromal cells (MSCs) for tissue engineering of hyaline cartilage is a topical area of regenerative medicine that has already entered clinical practice. The key stage of this procedure is to create conditions for chondrogenic differentiation of MSCs, increase the synthesis of hyaline cartilage extracellular matrix proteins by these cells and activate their proliferation. The first such works consisted in the indirect modification of cells, namely, in changing the conditions in which they are located, including microfracturing of the subchondral bone and the use of 3D biodegradable scaffolds. The most effective methods for modifying the cell culture of MSCs are protein and physical, which have already been partially introduced into clinical practice. Genetic methods for modifying MSCs, despite their effectiveness, have significant limitations. Techniques have not yet been developed that allow studying the effectiveness of their application even in limited groups of patients. The use of MSC modification methods allows precise regulation of cell culture proliferation, and in combination with the use of a 3D biodegradable scaffold, it allows obtaining a hyaline-like regenerate in the damaged area. This review is devoted to the consideration and comparison of various methods used to modify the cell culture of MSCs for their use in regenerative medicine of cartilage tissue.
