Abstract
Cells and tissues are the foundation of translational medicine. At present, one of the main technological obstacles is their preservation for long-term usage while maintaining adequate viability and function. Optimized storage techniques must be developed to make them safer to use in the clinic. Cryopreservation is the most common long-term preservation method to maintain the vitality and function of cells and tissues. But, the formation of ice crystals in cells and tissues is considered to be the main mechanism that could harm cells and tissues during freezing and thawing. To reduce the formation of ice crystals, cryoprotective agents (CPAs) must be added to the cells and tissues to achieve the cryoprotective effect. However, conventional cryopreservation of cells and tissues often needs to use toxic organic solvents as CPAs. As a result, cryopreserved cells and tissues may need to go through a time-consuming washing process to remove CPAs for further applications in translational medicine, and multiple valuable cells are potentially lost or killed. Currently, trehalose has been researched as a nontoxic CPA due to its cryoprotective ability and stability during cryopreservation. Nevertheless, trehalose is a nonpermeable CPA, and the lack of an effective intracellular trehalose delivery method has become the main obstacle to its use in cryopreservation. This article illustrated the properties, mechanisms, delivery methods, and applications of trehalose, summarized the benefits and limits of trehalose, and summed up the findings and research direction of trehalose in biomedical cryopreservation.

Optimization of chondrocyte isolation from human articular cartilage to preserve the chondrocyte transcriptome. Front Bioeng Biotechnol 2022; 10:1046127.

Abstract
The isolation of chondrocytes from human articular cartilage for single-cell RNA sequencing requires extensive and prolonged tissue digestion at 37 C. Modulations of the transcriptional activity likely take place during this period such that the transcriptomes of isolated human chondrocytes no longer match their original status in vivo. Here, we optimized the human chondrocyte isolation procedure to maximally preserve the in vivo transcriptome. Cartilage tissues were transferred into a hypoxia chamber (4% O2) immediately after being removed from OA patients and minced finely. Collagenase II at concentrations of 0.02%, 0.1%, 0.25%, 0.5%, 1%, and 2% was applied for 0.5, 1, 2, 4, and 18 h to digest the minced tissue. Actinomycin D (ActD) was added to test its capacity in stabilizing the transcriptome. Cell yield, viability, cell size, and transcriptome were determined using counter chamber, flow cytometry, and RNA sequencing (RNA-seq). Collagenase II at 2% concentration released small chondrocytes from cartilage matrix during the first digestion hour and started to release large cells thereafter, reaching a complete release at 4 h. During 4-h digestions, collagenase II at 2% and 1% but not at lower concentrations yielded maximal release also of the large chondrocyte population. RNA-seq analysis revealed that a 4-h digestion period with 1% or 2% collagenase II plus Actinomycin D optimally preserved the transcriptome. Thus, this study provides an isolation protocol for single chondrocytes from human articular cartilage optimized for transcriptome preservation and RNA-seq analysis.

Abstract
Background Dimethyl sulfoxide (DMSO) cryoprotectant can effectively alleviate the damage to single tissue during cryopreservation and restore its physiological activity after rewarming. However, studies have not been successful for preserving large tissue. This study aimed to investigate the application conditions of DMSO in large composite-tissue by performing femoral artery perfusion and soaking in a rabbit hind-limb model. Material/Methods A microdialysis-freezing point osmometer was used to detect the minimum time required for effective perfusion of 10% v/v perfusion and 20% v/v perfusion group. Magnetic resonance spectroscopy (MRS) was used to detect the area under the spectrum peak of DMSO in perivascular, intramuscular, subcutaneous areas, and compare the area under the spectrum peak in the 20% vascular perfusion group and other whole immersion groups. Results The minimum time required for effective perfusion of muscle in the 10% v/v group was 30 minutes, the DMSO concentration was stable at 5% v/v; In the 20% v/v group the minimum time was at 20 minutes, stable at 12% v/v. There was a statistically difference of the area under the spectrum peak in the 10% group and the 20% v/v group after vascular perfusion in different tissue locations (P<0.05). The 20% vascular perfusion group and the different concentration of DMSO in the large tissue soaking group were statistically different (P<0.05). There was a significant difference in the 20% v/v vascular perfusion group compared to the low concentration immersion group, but no difference compared to the 50% immersion group. Conclusions The effect of blood perfusion on cryopreservation in large tissue by using DMSO was slightly better than overall soaking, especially in preservation of skin and subcutaneous tissue.

Abstract
For the cartilage repair, the cell sources currently adopted are primarily chondrocytes or mesenchymal stem cells (MSCs). Due to the fact that chondrocytes dedifferentiate during 2-dimensional (2D) expansion, MSCs are generally more studied and considered to have higher potential for cartilage repair purposes. Here we question if the dedifferentiated chondrocytes can regain the chondrogenic potential, to find potential applications in cartilage repair. For this we chose chondrocytes at passage 12 (considered to have sufficiently dedifferentiated) and the expression of chondrogenic phenotypes and matrix syntheses were examined over 14 days. In particular, the chondrogenic potential of MSCs was also compared. Results showed that the dedifferentiated chondrocytes proliferated actively over 14 days with almost 2.5-fold increase relative to MSCs. Moreover, the chondrogenic ability of chondrocytes was significantly higher than that of MSCs, as confirmed by the expression of a series of mRNA levels and the production of cartilage extracellular matrix molecules in 2D-monolayer and 3-dimensional (3D)-spheroid cultures. Of note, the significance was higher in 3D-culture than in 2D-culture. Although more studies are needed such as the use of different cell passages and human cell source, and the chondrogenic confirmation under in vivo conditions, this study showing that the dedifferentiated chondrocytes can also be a suitable cell source for the cell-based cartilage repair, as a counterpart of MSCs, will encourage further studies regarding this issue.

Abstract
PURPOSE Abnormal growth of vertebral growth plate (VGP) was considered as one of the etiologic factors in adolescent idiopathic scoliosis (AIS). Previous studies described that estrogen played an important role in the pathogenesis of AIS. The present study was aimed to investigate the effect of estrogen/estrogen receptor axis on mouse VGP chondrocytes in vitro. METHODS Chondrocytes were isolated from mouse VGP and treated with or without 17β-estradiol (E2). Cell proliferation was measured by the cell growth rate assay. Gene expression of collagen type II and aggrecan were evaluated by real-time PCR. Expression of the proliferating cell nuclear antigen (PCNA), Sox9, and Smad4 were detected by Western blotting. RESULTS Estradiol inhibited the proliferation of VGP chondrocytes and the gene expression of collagen type II and aggrecan and downregulated the protein expression of PCNA, Sox9, and Smad4. In addition, the inhibitory effect of estradiol was reversed by ERβ small interfering RNA (siRNA) or PHTPP, an ERβ antagonist. CONCLUSIONS Estradiol via estrogen/estrogen receptor β axis inhibits the proliferation and differentiation of VGP chondrocytes, which might give some new insight into the regulatory mechanism of bone development.

Abstract
Increasing numbers of individuals are suffering from osteoarthritis every year, and the directed intra-articular injection of bone marrow stem cells has provided a promising treatment strategy for osteoarthritis. Although a number of studies have demonstrated that intra-articular injection of bone marrow stem cells produced desirable results, the mechanism underlying this effect has not been elucidated. In the current study, the effect of bone marrow stem cells on chondrocytes from patients with osteoarthritis was observed in a co-culture system. Human chondrocytes were obtained from patients with osteoarthritis who underwent surgical procedures and bone marrow stem cells were obtained from bone marrow aspirates, and then the chondrocytes were then cultured alone or cocultured with bone marrow stem cells in 0.4-µm Transwell inserts. The differentiation and biological activity of chondrocytes in the culture system were measured, and the inflammatory factors and OA-associated markers were also measured. The results indicated that coculture with human bone marrow stem cells increases cell proliferation of chondrocytes and inhibits inflammatory activity in osteoarthritis.

Abstract
Current protocols for chondrocyte isolation are inconsistent, resulting in suboptimal cell yield and compromised cell quality. Thus, there is a need for an improved isolation protocol that is able to give a maximum yield with optimal cell viability while preserving the chondrocyte phenotype. In light of this, we developed an improved isolation protocol based on enzymatic digestion using 0.1% (w/v) collagenase II. Different from existing methods of digesting minced cartilage for a prolonged period (usually 14-16 h), we performed two additional digestions, with a 5- and 3-h interval in between. The results showed that this multiple digestion method was able to yield a total number of cells that are more than a fivefold increase as compared to any of the common isolation protocols. More importantly, a high percentage of the isolated cells remained viable. Furthermore, an evaluation of the effect of additional digestions on chondrocyte phenotype indicated that cells harvested from the second and third digestion showed a comparable or higher proliferative capacity than the first digestion and all the cells expressed chondrocyte-specific markers tested, with cells from the third digestion showing exceptionally high gene expression levels for collagen type II (Col II), aggrecan, and COMP. Additionally, their ability to produce collagen type II as well as their morphology were not affected by the two additional digestions. Taken together, the results suggested that the use of this isolation protocol resulted in a higher cell yield and the quality of the isolated cells was maintained. Hence, we recommend this isolation protocol to be employed for more efficient cell harvesting especially from limited biopsied cartilage tissue samples.

Abstract
Cartilage tissue engineering is arising as a technique for the repair of cartilage lesions in clinical applications. However, fibrocartilage formation weakened the mechanical functions of the articular, which compromises the clinical outcomes. Due to the low proliferation ability, dedifferentiation property and low production of cartilage-specific extracellular matrix (ECM) of the chondrocytes, the cartilage synthesis in vitro has been one of the major limitations for obtaining high-quality engineered cartilage constructs. This review discusses cells, biomaterial scaffolds and stimulating factors that can facilitate the cartilage-specific ECM production and accumulation in the in vitro culture system. Special emphasis has been put on the factors that affect the production of ECM macromolecules such as collagen type II and proteoglycans in the review, aiming at providing new strategies to improve the quality of tissue-engineered cartilage.

Abstract
Temporo-mandibular joint disc disorders are highly prevalent in adult populations. Autologous chondrocyte implantation is a well-established method for the treatment of several chondral defects. However, very few studies have been carried out using human fibrous chondrocytes from the temporo-mandibular joint (TMJ). One of the main drawbacks associated to chondrocyte cell culture is the possibility that chondrocyte cells kept in culture tend to de-differentiate and to lose cell viability under in in-vitro conditions. In this work, we have isolated human temporo-mandibular joint fibrochondrocytes (TMJF) from human disc and we have used a highly-sensitive technique to determine cell viability, cell proliferation and gene expression of nine consecutive cell passages to determine the most appropriate cell passage for use in tissue engineering and future clinical use. Our results revealed that the most potentially viable and functional cell passages were P5–P6, in which an adequate equilibrium between cell viability and the capability to synthesize all major extracellular matrix components exists. The combined action of pro-apoptotic (TRAF5, PHLDA1) and anti-apoptotic genes (SON, HTT, FAIM2) may explain the differential cell viability levels that we found in this study. These results suggest that TMJF should be used at P5–P6 for cell therapy protocols.
