Characterization of Five Collagenous Biomaterials by SEM Observations, TG-DTA, Collagenase Dissolution Tests and Subcutaneous Implantation Tests. MATERIALS 2022; 15:ma15031155. [PMID: 35161098 PMCID: PMC8839282 DOI: 10.3390/ma15031155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 01/24/2022] [Accepted: 01/30/2022] [Indexed: 11/25/2022]
Abstract
Collagenous biomaterials that are clinically applied in dentistry have dermis-type and membrane-type, both of which are materials for promoting bone and soft tissue formation. The properties of materials supplied with different types could affect their biodegradation periods. The purpose of this study was to characterize five of these products by four different methods: scanning electron microscopy (SEM) observation, thermogravimetry-differential thermal analysis (TG-DTA), 0.01 wt% collagenase dissolution test, and subcutaneous implantation test in vivo. SEM micrographs revealed that both dermis and membranous materials were fibrous and porous. The membranous materials had higher specific derivative thermal gravimetry (DTG) peak temperatures in TG-DTA at around 320 °C, longer collagenase dissolution time ranging from about 300 to 500 min, and more longevity in mice exceeding 9 weeks than the dermis materials. There existed a correlation between the peak temperature in TG-DTA and the collagenase dissolution time. It was considered that higher cross-link degree among collagen fibrils of the membrane-type collagenous materials might account for these phenomena. The experimental protocol and numerical results obtained could be helpful for selection and future development of fibrous collagenous biomaterials in clinical use.

Abstract
Despite the formation of mechanically inferior fibrocartilage, microfracture (MF) still remains the gold standard to repair the articular cartilage defects in clinical settings. To date, although many tissue-engineering scaffolds have been developed to enhance the MF outcome, the clinical outcomes remain inconsistent. Decellularized extracellular matrix (dECM) is among the most promising scaffold for cartilage repair due to its inheritance of the natural cartilage components. However, the impact of dECM from different developmental stages on cellular chondrogenesis and therapeutic effect remains elusive, as the development of native cartilage involves the distinct temporal dependency of the ECM components and various growth factors. Herein, we hypothesized that the immature cartilage dECM at various developmental stages was inherently different, and would consequently impact the chondrogenic potential BMSCs. In this study, we fabricated three different unidirectional collagen-dECM scaffolds sourced from neonatal, childhood, and adolescent rabbit cartilage tissues, and identified the age-dependent biological variations, including DNA, cartilage-specific proteins, and growth factors; along with the mechanical and degradation differences. Consequently, the different local cellular microenvironments provided by these scaffolds led to the distinctive cell morphology, circularity, proliferation, chondrogenic genes expression, and chondrogenesis of BMSCs in vitro, and the different gross morphology, cartilage-specific protein production, and subchondral bone repair when in combination with microfracture in vivo. Together, this work highlights the immature cartilage dECM at different developmental stages that would result in the diversified effects to BMSCs, and childhood cartilage would be considered the optimal dECM source for the further development of dECM-based tissue engineering scaffolds in articular cartilage repair.

Abstract
Localized cartilage lesions in early osteoarthritis and acute joint injuries are usually treated surgically to restore function and relieve pain. However, a persistent clinical challenge remains in how to repair the cartilage lesions. We expressed doublecortin (DCX) in human adipose-derived stromal/stem cells (hASCs) and engineered hASCs into cartilage tissues using an in vitro 96-well pellet culture system. The cartilage tissue constructs with and without DCX expression were implanted in the knee cartilage defects of rabbits (n = 42) and monkeys (n = 12). Cohorts of animals were euthanized at 6, 12, and 24 months after surgery to evaluate the cartilage repair outcomes. We found that DCX expression in hASCs increased expression of growth differentiation factor 5 (GDF5) and matrilin 2 in the engineered cartilage tissues. The cartilage tissues with DCX expression significantly enhanced cartilage repair as assessed macroscopically and histologically at 6, 12, and 24 months after implantation in the rabbits and 24 months after implantation in the monkeys, compared to the cartilage tissues without DCX expression. These findings suggest that hASCs expressing DCX may be engineered into cartilage tissues that can be used to treat localized cartilage lesions.

Bilayered scaffold with 3D printed stiff subchondral bony compartment to provide constant mechanical support for long-term cartilage regeneration. J Orthop Translat 2021; 30:112-121. [PMID: 34722154 PMCID: PMC8526903 DOI: 10.1016/j.jot.2021.09.001] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 08/29/2021] [Accepted: 09/02/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND/OBJECTIVE We seek to figure out the effect of stable and powerful mechanical microenvironment provided by Ti alloy as a part of subchondral bone scaffold on long-term cartilage regeneration.Methods: we developed a bilayered osteochondral scaffold based on the assumption that a stiff subchondral bony compartment would provide stable mechanical support for cartilage regeneration and enhance subchondral bone regeneration. The subchondral bony compartment was prepared from 3D printed Ti alloy, and the cartilage compartment was created from a freeze-dried collagen sponge, which was reinforced by poly-lactic-co-glycolic acid (PLGA). RESULTS In vitro evaluations confirmed the biocompatibility of the scaffold materials, while in vivo evaluations demonstrated that the mechanical support provided by 3D printed Ti alloy layer plays an important role in the long-term regeneration of cartilage by accelerating osteochondral formation and its integration with the adjacent host tissue in osteochondral defect model at rabbit femoral trochlea after 24 weeks. CONCLUSION Mechanical support provided by 3D printing Ti alloy promotes cartilage regeneration by promoting subchondral bone regeneration and providing mechanical support platform for cartilage synergistically. TRANSLATIONAL POTENTIAL STATEMENT The raw materials used in our double-layer osteochondral scaffolds are all FDA approved materials for clinical use. 3D printed titanium alloy scaffolds can promote bone regeneration and provide mechanical support for cartilage regeneration, which is very suitable for clinical scenes of osteochondral defects. In fact, we are conducting clinical trials based on our scaffolds. We believe that in the near future, the scaffold we designed and developed can be formally applied in clinical practice.

Abstract
The bone-ligament interface transitions from a highly organized type I collagen rich matrix to a nonmineralized fibrocartilage region and finally to a mineralized fibrocartilage region that interfaces with the bone. Therefore, engineering the bone-ligament interface requires a biomaterial substrate capable of maintaining or directing the spatially defined differentiation of multiple cell phenotypes. To date the appropriate combination of biophysical and biochemical factors that can be used to engineer such a biomaterial substrate remain unknown. Here we show that microfiber scaffolds functionalized with tissue-specific extracellular matrix (ECM) components can direct the differentiation of MSCs toward the phenotypes seen at the bone-ligament interface. Ligament-ECM (L-ECM) promoted the expression of the ligament-marker gene tenomodulin (TNMD) and higher levels of type I and III collagen expression compared to functionalization with commercially available type I collagen. Functionalization of microfiber scaffolds with cartilage-ECM (C-ECM) promoted chondrogenesis of MSCs, as evidenced by adoption of a round cell morphology and increased SRY-box 9 (SOX9) expression in the absence of exogenous growth factors. Next, we fabricated a multiphasic scaffold by controlling the spatial presentation of L-ECM and C-ECM along the length of a single electrospun microfiber construct, with the distal region of the C-ECM coated fibers additionally functionalized with an apatite layer (using simulated body fluid) to promote endochondral ossification. These ECM functionalized scaffolds promoted spatially defined differentiation of MSCs, with higher expression of TNMD observed in the region functionalized with L-ECM, and higher expression of type X collagen and osteopontin (markers of endochondral ossification) observed at the end of the scaffold functionalized with C-ECM and the apatite coating. Our results demonstrate the utility of tissue-specific ECM derived components as a cue for directing MSC differentiation when engineering complex multiphasic interfaces such as the bone-ligament enthesis.

Abstract
Ideal tissue-engineering cartilage scaffolds should possess the same nanofibrous structure as the microstructure of native cartilage as well as the same biological function provided by the microenvironment for neocartilage regeneration. In the present study, three-dimensional composite biomimetic scaffolds with different concentration ratios of electrospun gelatin-polycaprolactone (gelatin-PCL) nanofibers and decellularized cartilage extracellular matrix (DCECM) were fabricated. The nanofibers with the biomimetic microarchitecture of native cartilage served as a skeleton with excellent mechanical properties, and the DCECM served as a biological functionalization platform for the induction of cell response and the promotion of cartilage regeneration. Experimental results showed that the composite nanofiber/DCECM (NF/DCECM) scaffolds had stronger mechanical properties and structural stability in wet state compared with those of DCECM scaffolds. In vitro experiments demonstrated that all scaffolds had good biocompatibility, but the chondrocyte proliferation rate of the composite NF/DCECM scaffolds was higher than that of the NF scaffolds. In vitro and in vivo cartilage regeneration results indicated that the DCECM component of the composite scaffolds facilitated early maturation of the cartilage lacuna and the secretion of collagen and glycosaminoglycan. The macroscopic and histological results at 12 weeks postsurgery exhibited that the composite NF/DCECM scaffolds yielded better cartilage repair outcomes than those of the nontreated group and NF scaffolds group. Overall, the present study demonstrated that the structurally and functionally biomimetic NF/DCECM scaffold is a promising tissue engineering scaffold for cartilage regeneration and cartilage defect repair.

Abstract
Cartilage repair using tissue engineering is the most advanced clinical application in regenerative medicine, yet available solutions remain unsuccessful in reconstructing native cartilage in its proprietary form and function. Previous investigations have suggested that the combination of specific bioactive elements combined with a natural polymer could generate carrier matrices that enhance activities of seeded stem cells and possibly induce the desired matrix formation. The present study sought to clarify this by assessing whether a chitosan-hyaluronic-acid-based biomimetic matrix in conjunction with adipose-derived stem cells could support articular hyaline cartilage formation in relation to a standard chitosan-based construct. By assessing cellular development, matrix formation, and key gene/protein expressions during in vitro cultivation utilizing quantitative gene and immunofluorescent assays, results showed that chitosan with hyaluronic acid provides a suitable environment that supports stem cell differentiation towards cartilage matrix producing chondrocytes. However, on the molecular gene expression level, it has become apparent that, without combinations of morphogens, in the chondrogenic medium, hyaluronic acid with chitosan has a very limited capacity to stimulate and maintain stem cells in an articular chondrogenic state, suggesting that cocktails of various growth factors are one of the key features to regenerate articular cartilage, clinically.

Abstract
OBJECTIVE The objective of this study was to describe the mechanism of healing of osteochondral defects of the distal femur in the sheep, a commonly used translational model. Information on the healing mechanism be useful to inform the design of tissue engineering devices for joint surface defect repair. DESIGN A retrospective study was conducted examining 7-mm diameter osteochondral defects made in the distal medial femoral condyle of 40 adult female sheep, comprising control animals from 3 separate structures. The healing of the defects was studied at post mortem at up to 26 weeks. RESULTS Osteochondral defects of the distal femur of the sheep heal through endochondral ossification as evidenced by chondrocyte hypertrophy and type X collagen expression. Neocartilage is first formed adjacent to damaged cartilage and then streams over the damaged underlying bone before filling the defect from the base upward. No intramembranous ossification or isolated mesenchymal stem cell aggregates were detected in the healing tissue. No osseous hypertrophy was detected in the defects. CONCLUSIONS Osteochondral defects of the medial femoral condyle of the sheep heal via endochondral ossification, with neocartilage first appearing adjacent to damaged cartilage. Unlike the mechanism of healing in fracture repair, neocartilage is eventually formed directly onto damaged bone. There was most variability between animals between 8 and 12 weeks postsurgery. These results should be considered when designing devices to promote defect healing.

Abstract
INTRODUCTION Human spontaneous osteonecrosis of the knee (SPONK) is still challenging as the current treatments do not allow the production of hyaline cartilage tissue. The aim of the present study was to explore the therapeutic potential of cartilage regeneration using a new biphasic scaffold (type I collagen/hydroxyapatite) previously loaded or not with concentrated bone marrow cells. MATERIAL AND METHODS Female rabbits were operated of one knee to create articular lesions of the trochlea (three holes of 4 × 4mm). The holes were left empty in the control group or were filled with the scaffold alone or the scaffold previously loaded with concentrated bone marrow cells. After two months, rabbits were sacrificed and the structure of the newly formed tissues were evaluated by macroscopic, MRI, and immunohistochemistry analyses. RESULTS Macroscopic and MRI evaluation of the knees did not show differences between the three groups (p > 0.05). However, histological analysis demonstrated that a higher O'Driscoll score was obtained in the two groups treated with the scaffold, as compared to the control group (p < 0.05). The number of cells in treated area was higher in scaffold groups compared to the control group (p < 0.05). There was no difference for intensity of collagen type II between the groups (p > 0.05) but subchondral bone repair was significantly thicker in scaffold-treated groups than in the control group (1 mm for the control group vs 2.1 and 2.6 mm for scaffold groups). Furthermore, we observed that scaffolds previously loaded with concentrated bone marrow were more reabsorbed (p < 0.05). CONCLUSION The use of a biphasic scaffold previously loaded with concentrated bone marrow significantly improves cartilage lesion healing.

Abstract
Articular cartilage lacks a blood supply and nerves. Hence, articular cartilage regeneration remains a major challenge in orthopedics. Decellularized extracellular matrix- (ECM-) based strategies have recently received particular attention. The structure of native cartilage exhibits complex zonal heterogeneity. Specifically, the development of a tissue-engineered scaffold mimicking the aligned structure of native cartilage would be of great utility in terms of cartilage regeneration. Previously, we fabricated oriented PLGA/ACECM (natural, nanofibrous, articular cartilage ECM) composite scaffolds. In vitro, we found that the scaffolds not only guided seeded cells to proliferate in an aligned manner but also exhibited high biomechanical strength. To detect whether oriented cartilage regeneration was possible in vivo, we used mesenchymal stem cell (MSC)/scaffold constructs to repair cartilage defects. The results showed that cartilage defects could be completely regenerated. Histologically, these became filled with hyaline cartilage and subchondral bone. Moreover, the aligned structure of cartilage was regenerated and was similar to that of native tissue. In conclusion, the MSC/scaffold constructs enhanced the structure-specific regeneration of hyaline cartilage in a rabbit model and may be a promising treatment strategy for the repair of human cartilage defects.

Abstract
Microfracture surgery may be improved by the implantation of unidirectional collagen scaffolds that provide a template for mesenchymal stem cells to regenerate cartilage. Incorporation of growth factors in unidirectional scaffolds may further enhance cartilage regeneration. In scaffolds, immobilization of growth factors is required to prolong in vivo activity, to limit diffusion and to reduce the amount of growth factor needed for safe clinical application. We investigated the immobilization of bone morphogenetic protein 2 (BMP2) to unidirectional collagen scaffolds and the effect on in vitro chondrogenesis. C3H10T1/2 cells were seeded on unidirectional collagen scaffolds with and without covalently attached heparin, and with and without incubation with BMP2 (1 and 10 μg), or with BMP2 present in the culture medium (10-200 ng ml-1). Culturing was for 2 weeks and readout parameters included histology, immunohistochemistry, biochemical analysis and molecular biological analysis. The unidirectional pores facilitated the distribution of C3H10T1/2 cells and matrix formation throughout scaffolds. The effective dose of medium supplementation with BMP2 was 100 ng ml-1 (total exposure 1 μg BMP2), and similar production of cartilage-specific molecules chondroitin sulfate (CS) and type II collagen was found for scaffolds pre-incubated with 10 μg BMP2. Pre-incubation with 1 μg BMP2 resulted in less cartilage matrix formation. The conjugation of heparin to the scaffolds resulted in more CS and less type II collagen deposition compared to scaffolds without heparin. In conclusion, unidirectional collagen scaffolds pre-incubated with 10 μg BMP2 supported chondrogenesis in vitro and may be suitable for prolonged cartilage matrix synthesis in vivo.

Improved cartilage regeneration by implantation of acellular biomaterials after bone marrow stimulation: a systematic review and meta-analysis of animal studies. PeerJ 2016; 4:e2243.

Abstract
Microfracture surgery may be applied to treat cartilage defects. During the procedure the subchondral bone is penetrated, allowing bone marrow-derived mesenchymal stem cells to migrate towards the defect site and form new cartilage tissue. Microfracture surgery generally results in the formation of mechanically inferior fibrocartilage. As a result, this technique offers only temporary clinical improvement. Tissue engineering and regenerative medicine may improve the outcome of microfracture surgery. Filling the subchondral defect with a biomaterial may provide a template for the formation of new hyaline cartilage tissue. In this study, a systematic review and meta-analysis were performed to assess the current evidence for the efficacy of cartilage regeneration in preclinical models using acellular biomaterials implanted after marrow stimulating techniques (microfracturing and subchondral drilling) compared to the natural healing response of defects. The review aims to provide new insights into the most effective biomaterials, to provide an overview of currently existing knowledge, and to identify potential lacunae in current studies to direct future research. A comprehensive search was systematically performed in PubMed and EMBASE (via OvidSP) using search terms related to tissue engineering, cartilage and animals. Primary studies in which acellular biomaterials were implanted in osteochondral defects in the knee or ankle joint in healthy animals were included and study characteristics tabulated (283 studies out of 6,688 studies found). For studies comparing non-treated empty defects to defects containing implanted biomaterials and using semi-quantitative histology as outcome measure, the risk of bias (135 studies) was assessed and outcome data were collected for meta-analysis (151 studies). Random-effects meta-analyses were performed, using cartilage regeneration as outcome measure on an absolute 0–100% scale. Implantation of acellular biomaterials significantly improved cartilage regeneration by 15.6% compared to non-treated empty defect controls. The addition of biologics to biomaterials significantly improved cartilage regeneration by 7.6% compared to control biomaterials. No significant differences were found between biomaterials from natural or synthetic origin or between scaffolds, hydrogels and blends. No noticeable differences were found in outcome between animal models. The risk of bias assessment indicated poor reporting for the majority of studies, impeding an assessment of the actual risk of bias. In conclusion, implantation of biomaterials in osteochondral defects improves cartilage regeneration compared to natural healing, which is further improved by the incorporation of biologics.
