Abstract
Mesenchymal stem cell (MSC) chondrogenesis in three-dimensional (3D) culture involves dynamic changes in cytoskeleton architecture during mesenchymal condensation before morphogenesis. However, the mechanism linking dynamic mechanical properties of matrix to cytoskeletal changes during chondrogenesis remains unclear. Here, we investigated how viscoelasticity, a time-dependent mechanical property of collagen hydrogel, coordinates MSC cytoskeleton changes at different stages of chondrogenesis. The viscoelasticity of collagen hydrogel was modulated by controlling the gelling process without chemical cross-linking. In slower-relaxing hydrogels, although a disordered cortical actin promoted early chondrogenic differentiation, persistent myosin hyperactivation resulted in Rho-associated kinase (ROCK)-dependent apoptosis. Meanwhile, faster-relaxing hydrogels promoted cell-matrix interactions and eventually facilitated long-term chondrogenesis with mitigated myosin hyperactivation and cell apoptosis, similar to the effect of ROCK inhibitors. The current work not only reveals how matrix viscoelasticity coordinates MSC chondrogenesis and survival in a ROCK-dependent manner but also highlights viscoelasticity as a design parameter for biomaterials for chondrogenic 3D culture.

Abstract
Optogenetics using light-sensitive proteins such as calcium transport channel rhodopsin (CatCh) opens up new possibilities for non-invasive remote manipulation of neural function. However, current optogenetic approaches for neurological disorder therapies rely on visible light excitation and are rarely applied to neurogenesis and nerve regeneration. Herein, we propose a new strategy for tissue engineering which combines optogenetic technology and biomimetic nerve scaffolds. Upconversion nanoparticles (UCNPs) were synthesized and integrated with oriented fibrillar PCL membranes with a collagen coating to establish neuro-matrix interfaces. Benefiting from the excellent bioactivity, oriented fibrillation and NIR-photoresponsivity, the CatCh-transfected PC12 cells on these interfaces exhibited enhanced cell elongation and neurite extension, as well as upregulated neurogenesis upon NIR excitation. Furthermore, a UCNP-integrated scaffold as an optogenetic actuator allowed NIR to penetrate dermal tissues to mediate neural activation, with an efficiency comparable to that of a 470 nm blue light. Compared with current visible light-excited optogenetics, our composite scaffold-mediated NIR stimulation addresses the problem of tissue penetration and will enable less-invasive neurofunctional manipulation, with the potential for remote therapy.

Abstract
Delivering electrical signals to neural cells and tissue has attracted increasing attention in the treatment of nerve injuries. Unlike traditional wired electrical stimulation, wireless and remote light stimulation provides less invasive and longer-lasting interfaces, holding great promise in the treatment of nerve injuries and neurodegenerative diseases, as well as human-computer interaction. Additionally, a bioactive matrix that bridges the injured gap and induces nerve regeneration is essential for injured nerve repair. However, it is still challenging to construct a 3D biomimetic cell niche with optoelectrical responsiveness. Herein, a bioactive platform for remote and wireless optoelectrical stimulation is established by incorporating hydrophilic poly(3-hexylthiophene) nanoparticles (P3HT NPs) into a biomimetic hydrogel matrix. Moreover, the hydrogel matrix is modified by varying the composition and/or the crosslinking degree to meet the needs of different application scenarios. When exposed to pulsed green light, P3HT NPs in hydrogels convert light signals into electrical signals, resulting in the generation of tens of picoampere photocurrent, which is proved to promote the growth of cortical neurons that covered by hydrogels and the neuronal differentiation of bone marrow mesenchymal stem cells (BMSCs) encapsulated in hydrogels. This work is of great significance for the design of next-generation neural electrodes and scaffolds.

Abstract
Hyaluronan (HA) provides a favorable environment for chondrogenesis of bone marrow mesenchymal stem cells (BMSCs). A previous report from our group indicated that addition of HA increases the chondro-inductive capacity of scaffolds. Therefore, this study aimed to investigate whether the Mw of the HA could affect chondrogenesis of BMSCs seeded on TCP-COL-HA scaffolds. Human BMSCs (hBMSCs) and rabbit BMSCs (rBMSCs) were isolated and expanded. TCP-COL scaffolds and TCP-COL-HA scaffolds with two different HA Mws were assessed for their capacity to induce cartilage regeneration from hBMSCs in vitro and in vivo. The results showed that about 96.96% of hBMSCs expressed CD44. Moreover, Hyal-1 and chondrogenic marker genes expressions were increased in hMSCs seeded on TCP-COL-HA scaffolds, and blocking the HA-CD44 interaction with an anti-CD44 antibody reduced the expression levels of Hyal-1 and chondrogenic marker genes. Additionally, TCP-COL-HA scaffolds with 2000 kDa Mw showed greater induction of BMSC chondrogenesis induction compared with those with 80 kDa Mw. Similar results were observed in an ectopic implantation nude mouse model. In a rabbit osteochondral defect repair model, rBMSCs seeded on TCP-COL-HA scaffolds with 2000 kDa Mw showed greater cartilage regeneration than those seeded with 80 kDa Mw. In addition, hBMSC-seeded TCP-COL-HA scaffolds with 2000 kDa Mw showed a significantly higher mechanical strength than those with 80 kDa Mw. Collectively, these results indicate that the Mw of HA could affect chondrogenesis of BMSCs seeded on TCP-COL-HA scaffolds. The TCP-COL-HA scaffolds might be used as allogenic off the shelf products in cartilage tissue engineering in future.

Abstract
BACKGROUND To regenerate tissue-engineered cartilage as a source of material for the restoration of cartilage defects, we used a human fetal cartilage progenitor cell pellet to improve chondrogenesis and modulation of the immune response in an in vivo bioreactor (IVB) system. METHODS IVB was buried subcutaneously in the host and then implanted into a cartilage defect. The IVB was composed of a silicone tube and a cellulose nano pore-sized membrane. First, fetal cartilage progenitor cell pellets were cultured in vitro for 3 days, then cultured in vitro, subcutaneously, and in an IVB for 3 weeks. First, the components and liquidity of IVB fluid were evaluated, then the chondrogenesis and immunogenicity of the pellets were evaluated using gross observation, cell viability assays, histology, biochemical analysis, RT-PCR, and Western blots. Finally, cartilage repair and synovial inflammation were evaluated histologically. RESULTS The fluid color and transparency of the IVB were similar to synovial fluid (SF) and the components were closer to SF than serum. The IVB system not only promoted the synthesis of cartilage matrix and maintained the cartilage phenotype, it also delayed calcification compared to the subcutaneously implanted pellets. CONCLUSION The IVB adopted to study cell differentiation was effective in preventing host immune rejection.

Abstract
OBJECTIVE To regenerate functional cartilage-mimicking ectopic cartilage as a source for the restoration of cartilage defects, we used a previously synthesized three-phase collagen, chondroitin sulfate and hyaluronic acid (CCH) hydrogel for the encapsulation of allogeneic chondrocytes with a diffusion chamber system that was buried subcutaneously in the host for 4 weeks and then implanted into a cartilage defect. METHODS The CCH hydrogel was prepared and seeded with allogeneic chondrocytes from new-born rabbits, prior to being enveloped in a diffusion chamber that prevents cell ingrowth and vascular invasion of the host, as described previously. A collagen hydrogel (C) was used as the control. The diffusion chamber was embedded subcutaneously in an adult rabbit. 4 weeks later, the regenerated tissue was harvested from the diffusion chamber and then further used for cartilage repair in the same host. To evaluate the regenerated tissue, cell viability assay using calcein-acetoxymethyl (calcein-AM)/propidium iodide (PI) staining, biochemical analysis by examination of total DNA and GAG content, gene expression detection using RT-PCR for Col 1a1, Col 2a1, Acan, and Sox9, biomechanical detection and histological evaluation were implemented. RESULTS Analysis of the cell activity and biochemical evaluation in vitro showed that cell proliferation, GAG secretion and gene/protein expression of cartilage specific markers were much higher in the CCH group than those in the C group. The CCH constructed ectopic cartilage tissue in vivo showed the typical characteristics of hyaline cartilage with higher expression of cartilage matrix markers compared with the C groups, as evidenced by morphological and histological findings as well as RT-PCR analysis. Furthermore, ectopic cartilage from CCH successfully facilitated the cartilage restoration, with higher morphological and histological scores and greater mechanical strength than that from C. CONCLUSION The three-phase CCH hydrogel, which is closer to natural cartilage matrix and is stiffer than collagen, may replace collagen as the "gold standard" for cartilage tissue engineering. This study may provide a new insight for cartilage repair using ectopic cartilage reconstructed from functional materials and allogeneic cells.

Abstract
Injectable and self-crosslinkable hydrogels have drawn much attention for their potential application as cell delivery carriers to deliver cells to the injury site of arbitrary shape. In this study, injectable and self-crosslinkable hydrogels were designed and fabricated based on collagen type I (Col I) and activated chondroitin sulfate (CS-sNHS) by physical and chemical crosslinking without the addition of any catalysts. The physical properties of hydrogels, including mechanical properties, swelling and degradation properties, were investigated. The results demonstrated that the physical properties of hydrogels, especially the stiffness of hydrogels, were readily tuned by varying the degree of substitution (DS) of CS-sNHS without changing the concentration of collagen-based precursor. Chondrocytes were encapsulated into hydrogels to investigate the effects of hydrogels on the survival, proliferation and extracellular matrix (ECM) secretion of cells by FDA/PI staining, CCK-8 test and histological staining. The results suggested that all of these hydrogels supported the survival and ECM secretion of chondrocytes, while there was more ECM secretion around chondrocytes encapsulated in hydrogel Col I/CS-sNHS56% in which the DS of CS-sNHS was 56%. When the neutral precursor solution for hydrogel of Col I or Col I/CS-sNHS56% was subcutaneously injected into SD rats, hydrogels both displayed acceptable biocompatibility in vivo. These results imply that these injectable and self-crosslinkable hydrogels are suitable candidates for applications in the fields of cell delivery and tissue engineering.

Abstract
The discovery of osteoinductivity of calcium phosphate (Ca-P) ceramics has set an enduring paradigm of conferring biological regenerative activity to materials with carefully designed structural characteristics. The unique phase composition and porous structural features of osteoinductive Ca-P ceramics allow it to interact with signaling molecules and extracellular matrices in the host system, creating a local environment conducive to new bone formation. Mounting evidence now indicate that the osteoinductive activity of Ca-P ceramics is linked to their physicochemical and three-dimensional structural properties. Inspired by this conceptual breakthrough, many laboratories have shown that other materials can be also enticed to join the rank of tissue-inducing biomaterials, and besides the bones, other tissues such as cartilage, nerves and blood vessels were also regenerated with the assistance of biomaterials. Here, we give a brief historical recount about the discovery of the osteoinductivity of Ca-P ceramics, summarize the underlying material factors and biological characteristics, and discuss the mechanism of osteoinduction concerning protein adsorption, and the interaction with different types of cells, and the involvement of the vascular and immune systems.

Abstract
As the seed cells, the immune properties of the mesenchymal stem cells are important for the tissue engineering restoring effect. But the in vivo research model is lacking. In the study, based on a dialyzer pocket model, changes in immunological properties and the differentiation of seeded mesenchymal stem cells (MSCs) in collagen hydrogel were studied in muscle and articular cavity implantation, respectively. The results showed that collagen hydrogel can induce MSCs to form cartilage tissue, followed by alteration of immunological properties. In muscle implantation, relatively low expression of major histocompatibility complex (MHC) molecules and low level of one-way mixed lymphocyte reactions (MLR) on the seeded MSCs were observed, but only a little cartilage tissue formed. In articular cavity implantation, more cartilage tissue formed, but higher MHC expressions and MLR level were found. Results indicated that the immunomodulation and the cartilage formation of the seeded MSCs will be impacted by the scaffold and the environment of the in vivo implanted site. The dialyzer pocket model can be used for the in vivo research for the MSC-based strategy of the tissue engineering, especially for the optimization of the immunomodulation.

Lu Z, Lei D, Jiang T, Yang L, Zheng L, Zhao J. Nerve growth factor from Chinese cobra venom stimulates chondrogenic differentiation of mesenchymal stem cells. Cell Death Dis 2017; 8:e2801. [PMID: 28518137 PMCID: PMC5520725 DOI: 10.1038/cddis.2017.208] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Revised: 03/29/2017] [Accepted: 04/06/2017] [Indexed: 01/08/2023]
Abstract
Growth factors such as transforming growth factor beta1 (TGF-β1), have critical roles in the regulation of the chondrogenic differentiation of mesenchymal stem cells (MSCs), which promote cartilage repair. However, the clinical applications of the traditional growth factors are limited by their high cost, functional heterogeneity and unpredictable effects, such as cyst formation. It may be advantageous for cartilage regeneration to identify a low-cost substitute with greater chondral specificity and easy accessibility. As a neuropeptide, nerve growth factor (NGF) was involved in cartilage metabolism and NGF is hypothesized to mediate the chondrogenic differentiation of MSCs. We isolated NGF from Chinese cobra venom using a three-step procedure that we had improved upon from previous studies, and investigated the chondrogenic potential of NGF on bone marrow MSCs (BMSCs) both in vitro and in vivo. The results showed that NGF greatly upregulated the expression of cartilage-specific markers. When applied to cartilage repair for 4, 8 and 12 weeks, NGF-treated BMSCs have greater therapeutic effect than untreated BMSCs. Although inferior to TGF-β1 regarding its chondrogenic potential, NGF showed considerably lower expression of collagen type I, which is a fibrocartilage marker, and RUNX2, which is critical for terminal chondrocyte differentiation than TGF-β1, indicating its chondral specificity. Interestingly, NGF rarely induced BMSCs to differentiate into a neuronal phenotype, which may be due to the presence of other chondrogenic supplements. Furthermore, the underlying mechanism revealed that NGF-mediated chondrogenesis may be associated with the activation of PI3K/AKT and MAPK/ERK signaling pathways via the specific receptor of NGF, TrkA. In addition, NGF is easily accessed because of the abundance and low price of cobra venom, as well as the simplified methods for separation and purification. This study was the first to demonstrate the chondrogenic potential of NGF, which may provide a reference for cartilage regeneration in the clinic.

Enhanced articular cartilage by human mesenchymal stem cells in enzymatically mediated transiently RGDS-functionalized collagen-mimetic hydrogels. Acta Biomater 2017; 51:75-88. [PMID: 28087486 PMCID: PMC5360098 DOI: 10.1016/j.actbio.2017.01.028] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2016] [Revised: 01/09/2017] [Accepted: 01/09/2017] [Indexed: 12/14/2022]
Abstract
Recapitulation of the articular cartilage microenvironment for regenerative medicine applications faces significant challenges due to the complex and dynamic biochemical and biomechanical nature of native tissue. Towards the goal of biomaterial designs that enable the temporal presentation of bioactive sequences, recombinant bacterial collagens such as Streptococcal collagen-like 2 (Scl2) proteins can be employed to incorporate multiple specific bioactive and biodegradable peptide motifs into a single construct. Here, we first modified the backbone of Scl2 with glycosaminoglycan-binding peptides and cross-linked the modified Scl2 into hydrogels via matrix metalloproteinase 7 (MMP7)-cleavable or non-cleavable scrambled peptides. The cross-linkers were further functionalized with a tethered RGDS peptide creating a system whereby the release from an MMP7-cleavable hydrogel could be compared to a system where release is not possible. The release of the RGDS peptide from the degradable hydrogels led to significantly enhanced expression of collagen type II (3.9-fold increase), aggrecan (7.6-fold increase), and SOX9 (5.2-fold increase) by human mesenchymal stem cells (hMSCs) undergoing chondrogenesis, as well as greater extracellular matrix accumulation compared to non-degradable hydrogels (collagen type II; 3.2-fold increase, aggrecan; 4-fold increase, SOX9; 2.8-fold increase). Hydrogels containing a low concentration of the RGDS peptide displayed significantly decreased collagen type I and X gene expression profiles, suggesting a major advantage over either hydrogels functionalized with a higher RGDS peptide concentration, or non-degradable hydrogels, in promoting an articular cartilage phenotype. These highly versatile Scl2 hydrogels can be further manipulated to improve specific elements of the chondrogenic response by hMSCs, through the introduction of additional bioactive and/or biodegradable motifs. As such, these hydrogels have the possibility to be used for other applications in tissue engineering. Statement of Significance Recapitulating aspects of the native tissue biochemical microenvironment faces significant challenges in regenerative medicine and tissue engineering due to the complex and dynamic nature of the tissue. The ability to take advantage of, mimic, and modulate cell-mediated processes within novel naturally-derived hydrogels is of great interest in the field of biomaterials to generate constructs that more closely resemble the biochemical microenvironment and functions of native biological tissues such as articular cartilage. Towards this goal, the temporal presentation of bioactive sequences such as RGDS on the chondrogenic differentiation of human mesenchymal stem cells is considered important as it has been shown to influence the chondrogenic phenotype. Here, a novel and versatile platform to recreate a high degree of biological complexity is proposed, which could also be applicable to other tissue engineering and regenerative medicine applications.

Abstract
UNLABELLED : The regeneration of tissue-engineered cartilage in an immunocompetent environment usually fails due to severe inflammation induced by the scaffold and their degradation products. In the present study, we compared the tissue remodeling and the inflammatory responses of engineered cartilage constructed with bone marrow mesenchymal stem cells (BMSCs), chondrocytes, or both and scaffold group in pigs. The cartilage-forming capacity of the constructs in vitro and in vivo was evaluated by histological, biochemical, and biomechanical analyses, and the inflammatory response was investigated by quantitative analysis of foreign body giant cells and macrophages. Our data revealed that BMSC-based engineered cartilage suppressed in vivo inflammation through the alteration of macrophage phenotype, resulting in better tissue survival compared with those regenerated with chondrocytes alone or in combination with BMSCs. To further confirm the macrophage phenotype, an in vitro coculture system established by engineered cartilage and macrophages was studied using immunofluorescence, enzyme-linked immunosorbent assay, and gene expression analysis. The results demonstrated that BMSC-based engineered cartilage promoted M2 polarization of macrophages with anti-inflammatory phenotypes including the upregulation of CD206, increased IL-10 synthesis, decreased IL-1β secretion, and alterations in gene expression indicative of M1 to M2 transition. It was suggested that BMSC-seeded constructs have the potential to ameliorate scaffold-induced inflammation and improve cartilaginous tissue regeneration through M2 polarization of macrophages. SIGNIFICANCE Finding a strategy that can prevent scaffold-induced inflammation is of utmost importance for the regeneration of tissue-engineered cartilage in an immunocompetent environment. This study demonstrated that bone marrow mesenchymal stem cell (BMSC)-based engineered cartilage could suppress inflammation by increasing M2 polarization of macrophages, resulting in better tissue survival in a pig model. Additionally, the effect of BMSC-based cartilage on the phenotype conversion of macrophages was further studied through an in vitro coculture system. This study could provide further support for the regeneration of cartilage engineering in immunocompetent animal models and provide new insight into the interaction of tissue-engineered cartilage and macrophages.

Abstract
This study was undertaken to explore the synergistic effect of scaffold materials and a cartilage-like environment on the chondrogenic differentiation of stem cells. Because stem cells encapsulated in a cartilage scaffold will be induced by scaffold molecules as well as permeable molecules from the surroundings, it is impossible to optimize a chondro-inducible scaffold without considering environmental sensitivity. How do we know if a designed scaffold will be sufficient prior to implantation? In this study, bone marrow mesenchymal stem cells (bMSCs) were seeded in various scaffolds, including collagen hydrogel, collage/sodium alginate hydrogel, collagen sponge and silk fibroin sponge. The cell-scaffold complex was encapsulated in a filter pocket to avoid direct contact with co-cultured chondrocytes. Scaffolds differed in the ability to adsorb inducible molecules expressed by chondrocytes, as evidenced by various expressions of cartilage specific proteins and genes. Collagen hydrogel unexpectedly supported chondrogenic differentiation in an environment filled with chondrocytes secretion better than other reinforced scaffolds, which is consistent with the previous experiment in vivo. This result indicated that the environmental sensitivity of a scaffold is important for in vivo chondro-induction. This in vitro scaffold-filter model may be useful as a precursor to investigate the chondro-inducing potential of various scaffolds for cartilage repair.

Abstract
Adipose-derived stem cells (ASCs) and mesenchymal stem cells are promising for tissue repair because of their multilineage differentiation capacity. Our previous data confirmed that the implantation of mixed ASCs and chondrocytes into cartilage defects induced desirable in vivo healing outcomes. However, the paracrine action of ASCs on chondrocytes needs to be further elucidated. In this study, we established a co-culture system to achieve cell-to-cell and cell-to-tissue crosstalk and explored the soluble growth factors in both ASCs and chondrocytes supplemented with 1% fetal bovine serum to mimic the physiological microenvironment. In ASCs, we screened for growth factors by semi-quantitative PCR and quantitative real-time PCR and found that the expression of bone morphogenetic protein 2 (BMP-2), vascular endothelial growth factor B (VEGFB), hypoxia inducible factor-1α (HIF-1α), fibroblast growth factor-2 (FGF-2), and transforming growth factor-β1 significantly increased after co-culture in comparison with mono-culture. In chondrocytes, VEGFA was significantly enhanced after co-culture. Unexpectedly, the expression of collagen II and aggrecan was significantly down-regulated in the co-culture group compared with the mono-culture group. Meanwhile, among all the growth factors screened, we found that the BMP family members BMP-2, BMP-4, and BMP-5 were down-regulated and that VEGFB, HIF-1α, FGF-2, and PDGF were significantly decreased after co-culture. These results suggest that crosstalk between ASCs and chondrocytes is a pathway through the regulated growth factors that might have potential in cartilage repair and regeneration and could be useful for tissue engineering.

Abstract
Articular cartilage is the load-bearing tissue found inside all articulating joints of the body. It vastly reduces friction and allows for smooth gliding between contacting surfaces. The structure of articular cartilage matrix and cellular composition is zonal and is important for its mechanical properties. When cartilage becomes injured through trauma or disease, it has poor intrinsic healing capabilities. The spectrum of cartilage injury ranges from isolated areas of the joint to diffuse breakdown and the clinical appearance of osteoarthritis. Current clinical treatment options remain limited in their ability to restore cartilage to its normal functional state. This review focuses on the evolution of biomaterial scaffolds that have been used for functional cartilage tissue engineering. In particular, we highlight recent developments in multiscale biofabrication approaches attempting to recapitulate the complex 3D matrix of native articular cartilage tissue. Additionally, we focus on the application of these methods to engineering each zone of cartilage and engineering full-thickness osteochondral tissues for improved clinical implantation. These methods have shown the potential to control individual cell-to-scaffold interactions and drive progenitor cell differentiation into a chondrocyte lineage. The use of these bioinspired nanoengineered scaffolds hold promise for recreation of structure and function on the whole tissue level and may represent exciting new developments for future clinical applications for cartilage injury and restoration.

Abstract
PURPOSE For scaffolds in cartilage tissue engineering, it is the principle to design the materials with both favorable mechanical and biological property. METHODS In this article, collagen hydrogels modified by two ways to improve mechanical strength were applied for in vivo cartilage reconstruction: one is collagen-alginate hydrogel (CAH) representative of mixture, the other is collagen hydrogel crosslinked by genipin (CGH). To investigate the biological activities of the two materials, it was designed as: scaffolds loaded with allogenous chondrocytes were encased in diffusion chamber, and then implanted subcutaneously in SD rats for 8 weeks. RESULTS Histologic, immunohistochemical, and RT-PCR results showed that collagen type Ⅱ and GAG, indicator of cartilage extracellular matrix (ECM) was highly expressed in constructs of chondrocyte-CAH. Significantly lower cell density and expression of cartilage specific protein were shown in constructs of chondrocyte-CGH than that in chondrocyte-CAH. This demonstrated that CAH may provide a more favorable environment for cartilage reconstruction. In addition, the model with diffusion chamber technique was viable for evaluation of scaffolds in vivo cartilage engineering in immunocompetent host. Instead, directly reconstruction of ectopic cartilage without diffusion chamber suffered from damaged tissue and less neo-cartilage matrix formed. CONCLUSIONS In conclusion, CAH is realistic as scaffold for in vivo cartilage tissue engineering with both satisfactory mechanical properties and biomimetic activity. And the model with diffusion chamber to reconstruct ectopic cartilage in immunocompetent animals is promising for evaluation of scaffolds. This study provided a new insight for in vivo cartilage tissue engineering.

Abstract
Certain materials may mimic natural cartilage to provide an amenable cellular microenvironment for the chondrogenic differentiation of mesenchymal stem cells. The chondrogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) has been demonstrated to be induced by collagen-based hydrogels in vivo, but whether the induction is material-driven or self-differentiation has not been elucidated. In the present study, BMSCs were encapsulated in porous materials, namely, a biphasic calcium phosphate ceramic (BCP), silk fibroin protein matrix (SFP) and collagen sponge (CS), to further study the chondrogenic effects of various materials. Diffusion chambers that allow the body fluid to permeate and deter the host cells from invasion were also loaded with the cell-scaffold constructs. Chambers containing the scaffold-BMSC composites were implanted subcutaneously in the dorsa of rabbits. The specimens in the chamber were harvested for histological and immunohistochemical analyses eight weeks after implantation. The results showed that no chondrogenic differentiation of the BMSCs occurred when the BMSCs were encapsulated in BCP, SFP and CS, indicating that chondrogenesis induced by materials is material-dependent and that these particular porous materials are not suitable for inducing chondrogenesis. However, the diffusion chamber was effective in preventing host immune rejection, host cell invasion and vascular invasion. The results are likely to serve as a valuable clinical reference when selecting an appropriate scaffold for cartilage repair.

Abstract
Chondrocytes (CH) and bone marrow stem cells (BMSCs) are sources that can be used in cartilage tissue engineering. Co-culture of CHs and BMSCs is a promising strategy for promoting chondrogenic differentiation. In this study, articular CHs and BMSCs were encapsulated in PCL-PEG-PCL photocrosslinked hydrogels for 4 weeks. Various ratios of CH:BMSC co-cultures were investigated to identify the optimal ratio for cartilage formation. The results thus obtained revealed that co-culturing CHs and BMSCs in hydrogels provides an appropriate in vitro microenvironment for chondrogenic differentiation and cartilage matrix production. Co-culture with a 1:4 CH:BMSC ratio significantly increased the synthesis of GAGs and collagen. In vivo cartilage regeneration was evaluated using a co-culture system in rabbit models. The co-culture system exhibited a hyaline chondrocyte phenotype with excellent regeneration, resembling the morphology of native cartilage. This finding suggests that the co-culture of these two cell types promotes cartilage regeneration and that the system, including the hydrogel scaffold, has potential in cartilage tissue engineering.

J Biomed Mater Res A 2013; 102:2725-35.

Abstract
Application of chondrogenic growth factors is a routine strategy to induce chondrogenesis of hMSCs, but they have economic and safety problems in the long term. It is expected that scaffold material itself could play an important role in chondrogenesis of hMSCs. In this study we tested whether a novel tricalcium phosphate-collagen-hyaluronan scaffold (TCP-COL-HA) had inherent chondro-inductive capacity for chondrogenesis of both ATDC5 and hMSCs without any exogenous growth factors in vitro. hMSCs and ATDC5 were seeded onto TCP-COL-HA scaffolds and cultured in basal medium for 3 weeks to investigate whether the TCP-COL-HA scaffold itself had differentiation-inductive capacity in basal culture. With hMSCs-seeded scaffold in chondrogenic medium (including TGF-β1) as positive control, we then compared the chondrogenic induction of TCP-COL-HA in basal culture and in chondrogenic culture. The chondrogenic differentiation was evaluated by sulfated glycosaminoglycans (GAGs) quantification, type II collagen immunohistochemistry, and RT-PCR. Mechanical strength was evaluated by compression test and the cell death rate of hMSCs was assessed with TUNEL assay. The results showed TCP-COL-HA scaffold itself could efficiently induce chondrogenic differentiation of both ATDC5 and hMSCs after 3 weeks in basal culture. The accumulation of GAGs and the expression of chondrocyte marker genes were all significantly increased. In addition, hMSCs-seeded scaffold showed a significantly higher mechanical strength after 3 weeks in basal culture. The chondrogenic induction of TCP-COL-HA scaffolds in basal medium were almost similar to that in chondrogenic medium on hMSCs. The chondrogenesis-inducing capacity of TCP-COL-HA scaffold might help to improve cartilage tissue engineering with economic and safe benefits.

Abstract
A collagen type I hydrogel was constructed and used as the scaffold for cartilage tissue engineering. Neonatal rabbit chondrocytes were seeded into the hydrogel, and the constructs were cultured in vitro for 7, 14, and 28 days. The immunomodulatory effect of the hydrogel on seeded chondrocytes was carefully investigated. The expressions of major histocompatibility complex classes I and II of seeded chondrocytes increased with the time, which indicated that the immunogenicity also increased with the time. Meanwhile, the properly designed collagen type I hydrogel could prompt the chondrogenesis of engineered cartilage. The extracellular matrix (ECM) synthesis ability of seeded chondrocytes and the accumulated ECM in the constructs continuously increased with the culture time. Both the isolation and protection, which come from formed ECM and hydrogel scaffold, can effectively control the adverse immunogenicity of seeded chondrocytes and even help to lessen the immunogenicity of the whole engineered cartilage. As the result, the levels of mixed lymphocyte chondrocyte reactions of seed cells and the constructs decreased gradually. The stimulation on allogeneic lymphocytes of the whole constructs was obviously lower than that of the retrieved cells from the constructs. Therefore, properly designed collagen type I hydrogel can give certain immunogenicity-reducing effects on engineered cartilage based on chondrocytes, and it may be a potential immunomodulatory biomaterial in tissue engineering.

Abstract
Cell therapy has emerged as a potential therapeutic strategy in regenerative disease. Among different cell types, mesenchymal stem/stromal cells have been wildly studied in vitro, in vivo in animal models and even used in clinical trials. However, while clinical applications continue to increase markedly, the understanding of their physiological properties and interactions raises many questions and drives the necessity of more caution and supervised strategy in their use.

Abstract
Tissue engineering scaffolds are commonly formed using proteins extracted from animal tissues, such as bovine hide. Risks associated with the use of these materials include hypersensitivity and pathogenic contamination. Human-derived proteins lower the risk of hypersensitivity, but possess the risk of disease transmission. Methods engineering recombinant human proteins using plant material provide an alternate source of these materials without the risk of disease transmission or concerns regarding variability. To investigate the utility of plant-derived human collagen (PDHC) in the development of engineered skin (ES), PDHC and bovine hide collagen were formed into tissue engineering scaffolds using electrospinning or freeze-drying. Both raw materials were easily formed into two common scaffold types, electrospun nonwoven scaffolds and lyophilized sponges, with similar architectures. The processing time, however, was significantly lower with PDHC. PDHC scaffolds supported primary human cell attachment and proliferation at an equivalent or higher level than the bovine material. Interleukin-1 beta production was significantly lower when activated THP-1 macrophages where exposed to PDHC electrospun scaffolds compared to bovine collagen. Both materials promoted proper maturation and differentiation of ES. These data suggest that PDHC may provide a novel source of raw material for tissue engineering with low risk of allergic response or disease transmission.

Abstract
OBJECTIVE To investigate whether icariin, which is a widely used pharmacological constituent in traditional Chinese herbal medicine, can be a potential promoting compound for cartilage tissue engineering. DESIGN Icariin was added into cell-hydrogel constructs derived from neonatal rabbit chondrocytes and collagen type I. The chondrogenic gene expressions and the synthesis of cartilage matrix of the seeded cells were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Biochemical assay. The effects of icariin-added cell-hydrogel constructs on the restoration of supercritical-sized osteochondral defects of adult rabbit were investigated by histological observation. The cell-hydrogel constructs without Icariin were set for controls. RESULTS Icariin obviously up-regulate the expressions included aggrecan, sox9, and collagen type II of seeded chondrocytes from 99.7% to 248%. It increases the synthesis of glycosaminoglycan and collagen type II about fourfold to fivefolds from week 1 to week 4, and accelerates the formation of chondroid tissue in the cell-hydrogel constructs. Even, it improves the restoration efficiency of supercritical-sized osteochondral defects in adult rabbit model, and enhances the integration of new-formed cartilage with subchondral bone. CONCLUSIONS Icariin can be a potential promoting compound for cartilage tissue engineering, and it can be a substitute for the use of some growth factors. The long history and extensive cases of safe use in China, Japan and Korea make it more attractive.

Abstract
It is controversial whether a biomaterial itself, rather than addition of any exogenous growth factor, could induce mesenchymal stem cells (MSCs) to differentiate into chondrogenic lineage, further to regenerate cartilage. Previous studies have shown that collagen-based hydrogel could induce MSCs to differentiate into chondrocytes in vivo but the in vitro studies only have a few reports. The evidence that biomaterials could induce chondrogenesis is not adequate. In this study, we tried to address whether type I collagen hydrogel has chondro-inductive capability in vitro and how this scaffold induces MSCs to generate cartilage tissue without exogenous growth factors in the culture medium. We encapsulated neonatal rabbit bone marrow mesenchymal stem cells (BMSCs) in type I collagen hydrogel homogeneously or implanted cell aggregates in hydrogel, and cultured them in nonchondrogenic inductive media. After at least 28 days culture, cells in the homogeneous group were tending to chondrogenic differentiation while cell density was high, and cells in the aggregate group have almost gone through chondrogenesis and formed neo-cartilage tissue with abundant specific extracellular matrix (ECM) deposition. These results indicate collagen hydrogel has inherent inductivity for the chondrogenic differentiation of BMSCs, and the optimum specification and tissue formation were accompanied with local high cell density. This research suggests a feasible strategy to induce the chondro differentiation of BMSCs independent of exogenous growth factors, which may greatly contribute to clinical cartilage regeneration.

Abstract
Tissue engineering is a technique by which a live tissue can be re-constructed and one of its main goals is to associate cells with biomaterials. Electrospinning is a technique that facilitates the production of nanofibers and is commonly used to develop fibrous scaffolds to be used in tissue engineering. In the present study, a different approach for cell incorporation into fibrous scaffolds was tested. Mesenchymal stem cells were extracted from the wall of the umbilical cord and mononuclear cells from umbilical cord blood. Cells were re-suspended in a 10% polyvinyl alcohol solution and subjected to electrospinning for 30 min under a voltage of 21 kV. Cell viability was assessed before and after the procedure by exclusion of dead cells using trypan blue staining. Fiber diameter was observed by scanning electron microscopy and the presence of cells within the scaffolds was analyzed by confocal laser scanning microscopy. After electrospinning, the viability of mesenchymal stem cells was reduced from 88 to 19.6% and the viability of mononuclear cells from 99 to 8.38%. The loss of viability was possibly due to the high viscosity of the polymer solution, which reduced the access to nutrients associated with electric and mechanical stress during electrospinning. These results suggest that the incorporation of cells during fiber formation by electrospinning is a viable process that needs more investigation in order to find ways to protect cells from damage.

Abstract
Engineered implants derived from neonatal rabbit chondrocytes and collagen type I hydrogel, were loaded in dialyzer pockets and implanted in muscle and articular cavity of rabbits to simulate different stress and tissue fluid micro-environments. After 4 and 12 weeks, the expressions of main histocompatibility complex (MHC) molecules as well as the mixed lymphocyte chondrocytes reactions (MLChR) levels of the seeded cells were detected. The results indicated that with stress and synovial fluid microenvironment, the formation of chondroid tissue was prominently promoted in articular cavity. It gave the seeded chondrocytes lower and gradually decreasing levels of allogeneic lymphocytes activation, however, with the higher cell mortality, the MHC molecules expression, especially MHC-I were up-regulated obviously in early stage. These results are very different to those seen in muscle and prove that stress and tissue fluid micro-environments can greatly impact the differentiation and immunological properties of the engineered cartilage. From the perspective of avoiding severe rejection, to promote the formation of the matrix as fast and select scaffold with higher "isolation" ability may be meaningful. Furthermore, the suitably treated dialyzer pockets model can be used for the study of the differentiation and immunological properties of the tissue engineered cartilage.

Abstract
Allogeneic mesenchymal stem cells (MSCs) are regarded as promising seed cells for engineering cartilage. However, few researches have covered the immune properties of seeded MSCs. Collagen has been considered as good scaffold, whether it has inherent chondrogenic inducibility for MSCs is still in debate. In this study, engineering grafts are constructed by neonatal rabbit MSCs and collagen Type I hydrogel. After periods of culture, the appearance of chondroid tissue in the grafts and the cartilage matrix-specific genes expressions of seeded cells prove the inducibility of collagen hydrogel, even if the growth factors are absence. With the differentiation, immunological properties of MSCs are changing. The expressions of main histocompatibility complex (MHC) molecules increase and the ability to inhibit the proliferation of activated lymphocytes may be declined. But to a large extent, it keeps the low stimulating to allogeneic lymphocytes and the small absolute value of MHCs. The changes are adverse for avoiding inflammation and rejection. Therefore, suitable scaffold and engineering strategies should be selected. For the grafts based on Collagen I hydrogel and MSCs, a longer culture period might not be necessary. To maintain the immune regulation, a higher initial MSCs density in engineering grafts may be more meaningful.

Abstract
Recent progress in cell therapy research has raised the need for non-invasive monitoring of transplanted cells. Magnetic resonance imaging (MRI) of superparamagnetic iron oxide (SPIO) labeled cells have been widely used for high resolution monitoring of the biodistribution of cells after transplantation. Here we report that self-assembly of amphiphilic polyethylenimine (PEI)/SPIO nanocomposites can lead to the formation of ultrasensitive MRI probes, which can be used to label chondrocyte cells with good biocompatibility. The labeled cells display strong signal contrast compared to unlabeled ones in a clinical MRI scanner. This probe may be useful for noninvasive MR tracking of implanted cells for tissue regeneration.

Abstract
OBJECTIVE Our goal was to test the recombinant human type II collagen (rhCII) material as a gel-like scaffold for chondrocytes in a nude mouse model in vivo. DESIGN Isolated bovine chondrocytes (6x10(6)) were seeded into rhCII gels (rhCII-cell) and injected subcutaneously into the backs of nude mice. For comparison, chondrocytes (6x10(6)) in culture medium (Med-cell) and cell-free rhCII gels (rhCII-gel) were similarly injected (n=24 animals, total of three injections/animal). After 6 weeks, the tissue constructs were harvested and analyzed. RESULTS Chondrocytes with or without rhCII-gel produced white resilient tissue, which in histological sections had chondrocytes in lacunae-like structures. Extracellular matrix stained heavily with toluidine blue stain and had strongly positive collagen type II immunostaining. The tissue did not show any evidence of vascular invasion or mineralization. The cell-free rhCII-gel constructs showed no signs of cartilage tissue formation. Cartilage tissue produced by Med-cell was thin and macroscopically uneven, while the rhCII-cell construct was smooth and rounded piece of neotissue. RhCII-cell constructs were statistically thicker than Med-cell ones. However, no statistical differences were found between the groups in terms of glycosaminoglycan (GAG) content or biomechanical properties. CONCLUSIONS These results show that rhCII-gel provides good expansion and mechanical support for the formation of cartilage neotissue. RhCII material may allow favorable conditions in the repair of chondral lesions.
