Abstract
Restoration of the 3-dimensional structure of the facial and calvarial skeleton after trauma or ablative oncologic surgeries serves as a framework for soft tissue reconstruction. In the present study, the authors aimed to evaluate the osteogenic effect of artificial dermis and epidermal growth factor treatment in critical-sized calvarial defects, which cannot be healed spontaneously. 8 mm calvarial defects were created in 28 male rats and filled with the artificial dermis, the artificial dermis and growth factor, growth factor or left untreated. Atomic absorption spectrometry was used to determine the amount of calcium, scanning electron microscopy was used to show the bone tissue in 3 dimensions, and immunohistochemistry was used to assess the bone formation and cell density. Histologic evaluation at 6 weeks showed incomplete bone regeneration in all groups. No statistical differences were found between the groups with regard to their scores for the following: inflammation, new bone formation, osteocyte density, resorption of bone at the edges of the defect, or fibrous tissue formation in the defect area. In conclusion, the predictability of bone formation in critical-size defects is not clear. Contrary to popular belief, the combined use of epidermal growth factor with artificial dermis or alone did not enhance the potential for osseous healing.

Abstract
Biomaterial-based therapies have been receiving attention for treating microbial infections mainly to overcome the increasing number of drug-resistant bacterial strains and off-target impacts of therapeutic agents by conventional strategies. A fibrous, non-soluble protein, collagen, is one of the most studied biopolymers for the development of antimicrobial biomaterials owing to its superior physicochemical, biomechanical, and biological properties. In this study, we reviewed the different approaches used to develop collagen-based antimicrobial devices, such as non-pharmacological, antibiotic, metal oxide, antimicrobial peptide, herbal extract-based, and combination approaches, with a particular focus on preclinical studies that have been published in the last decade.

Abstract
OBJECTIVE Coverage of upper and lower extremity wounds with exposed vital structures such as tendon and bone is reliant on pedicled and free flaps. However, a population of patients with medical comorbidities or other social issues may not be suitable for flap coverage. We present the first in patient clinical experience in the US with MatriDerm (Billerbeck, Germany) for treatment of difficult extremity wounds, all with exposed bone or tendon. METHOD MatriDerm dermal matrix has been popular in Europe for coverage of wounds. However, MatriDerm only received full approval for use by the US Food and Drug Administration (FDA) in 2021. Here we review our clinical experience. RESULTS Locations (n=11) treated included forearm (n=1), hand (n=4), leg (n=3), and feet (n=3). Vital structures in wounds exposed included bone (n=3), bone and tendon (n=1), and tendon (n=7). Mean area of the wound treated was 59.2cm2 (range: 2 to 230). In our series, eight out of 11 wounds healed, with MatriDerm only (n=6) or following delayed skin grafting (n=2). Mean time to healing in the patients treated only with MatriDerm was 49 days (range 7 to 84). Mean time to split-thickness skin grafting in the remaining two patients was 44.5 days (range 32 to 57). CONCLUSION MatriDerm has potential for treatment of complex extremity wounds, which would otherwise require flap coverage, in patients who are not good candidates for flap surgery.

Abstract
Hydrogel is in the spotlight as a useful biomaterial in the field of drug delivery and tissue engineering due to its similar biological properties to a native extracellular matrix (ECM). Herein, we proposed a ternary hydrogel of gellan gum (GG), silk fibroin (SF), and chondroitin sulfate (CS) as a biomaterial for cartilage tissue engineering. The hydrogels were fabricated with a facile combination of the physical and chemical crosslinking method. The purpose of this study was to find the proper content of SF and GG for the ternary matrix and confirm the applicability of the hydrogel in vitro and in vivo. The chemical and mechanical properties were measured to confirm the suitability of the hydrogel for cartilage tissue engineering. The biocompatibility of the hydrogels was investigated by analyzing the cell morphology, adhesion, proliferation, migration, and growth of articular chondrocytes-laden hydrogels. The results showed that the higher proportion of GG enhanced the mechanical properties of the hydrogel but the groups with over 0.75% of GG exhibited gelling temperatures over 40 °C, which was a harsh condition for cell encapsulation. The 0.3% GG/3.7% SF/CS and 0.5% GG/3.5% SF/CS hydrogels were chosen for the in vitro study. The cells that were encapsulated in the hydrogels did not show any abnormalities and exhibited low cytotoxicity. The biochemical properties and gene expression of the encapsulated cells exhibited positive cell growth and expression of cartilage-specific ECM and genes in the 0.5% GG/3.5% SF/CS hydrogel. Overall, the study of the GG/SF/CS ternary hydrogel with an appropriate content showed that the combination of GG, SF, and CS can synergistically promote articular cartilage defect repair and has considerable potential for application as a biomaterial in cartilage tissue engineering.

Abstract
BACKGROUND In periodontal patients with jawbone resorption, the autologous bone graft is considered a "gold standard" procedure for the placing of dental prosthesis; however, this procedure is a costly intervention and poses the risk of clinical complications. Thanks to the use of adult mesenchymal stem cells, smart biomaterials, and active biomolecules, regenerative medicine and bone tissue engineering represent a valid alternative to the traditional procedures. AIMS In the past, mesenchymal stem cells isolated from periodontally compromised gingiva were considered a biological waste and discarded during surgical procedures. This study aims to test the osteoconductive activity of FISIOGRAFT Bone Granular® and Matriderm® collagen scaffolds on mesenchymal stem cells isolated from periodontally compromised gingiva as a low-cost and painless strategy of autologous bone tissue regeneration. MATERIALS AND METHODS We isolated human mesenchymal stem cells from 22 healthy and 26 periodontally compromised gingival biopsy tissues and confirmed the stem cell phenotype by doubling time assay, colony-forming unit assay, and expression of surface and nuclear mesenchymal stem cell markers, respectively by cytofluorimetry and real-time quantitative PCR. Healthy and periodontally compromised gingival mesenchymal stem cells were seeded on FISIOGRAFT Bone Granular® and Matriderm® scaffolds, and in vitro cell viability and bone differentiation were then evaluated. RESULTS Even though preliminary, the results demonstrate that FISIOGRAFT Bone Granular® is not suitable for in vitro growth and osteogenic differentiation of healthy and periodontally compromised mesenchymal stem cells, which, instead, are able to grow, homogeneously distribute, and bone differentiate in the Matriderm® collagen scaffold. CONCLUSION Matriderm® represents a biocompatible scaffold able to support the in vitro cell growth and osteodifferentiation ability of gingival mesenchymal stem cells isolated from waste gingiva, and could be employed to develop low-cost and painless strategy of autologous bone tissue regeneration.

Abstract
La fibroína de Bombyx mori L., es un biomaterial que se ha utilizado por sus características físico/químicas que la hacen útil para la curación de múltiples tejidos. En el contexto de la medicina regenerativa caracterizar a nivel físico y biológico nuevos soportes preparados a partir de fibroína de seda y evaluar su capacidad para la proliferación de fibroblastos humanos, brinda una gran oportunidad para encontrar nuevos biomateriales con aplicaciones favorables en la curación de heridas. Se utilizó fibroína regenerada al 17% para la fabricación de matrices. Estas fueron caracterizadas teniendo en cuenta: estabilidad en condiciones de cultivo, ultraestructura, porosidad, ángulo de contacto y propiedades mecánicas. El grosor promedio de las matrices de fibroína fue 30,1µm, con una estabilidad superior a 4 semanas en condiciones de cultivo, porosidad del 51% y una capacidad de retención de líquidos del 95%, un ángulo de contacto de 44,5° y un módulo de elasticidad de aproximadamente 200 MPa. Finalmente se evaluó la capacidad del andamio para soportar el crecimiento de fibroblastos humanos. Identificando que los andamios permiten la multiplicación celular, mostrando bajos índices de citotoxicidad (<5%); las células establecieron interacciones fuertes con el andamio, mediante la producción de filopodios y la producción de matriz extracelular propia. Concluyendo esto, que es un andamio compatible de fibroblastos humanos en los procesos para el crecimiento y multiplicación celular en procesos de medicina regenerativa.

Abstract
Background Since the treatments of long tracheal lesions are associated with some limitations, tissue engineered trachea is considered as an alternative option. This study aimed at preparing a composite scaffold, based on natural and synthetic materials for tracheal tissue engineering. Methods Nine chitosan silk-based scaffolds were fabricated using three freezing rates (0.5, 1, and 2°C/min) and glutaraldehyde (GA) concentrations (0, 0.4, and 0.8 wt%). Samples were characterized, and scaffolds having mechanical properties compatible with those of human trachea and proper biodegradability were selected for chondrocyte cell seeding and subsequent biological assessments. Results The pore sizes were highly influenced by the freezing rate and varied from 135.3×372.1 to 37.8×83.4 µm. Swelling and biodegradability behaviors were more affected by GA rather than freezing rate. Tensile strength raised from 120 kPa to 350 kPa by an increment of freezing rate and GA concentration. In addition, marked stiffening was demonstrated by increasing elastic modulus from 1.5 MPa to 12.2 MPa. Samples having 1 and 2°C/min of freezing rate and 0.8 wt% GA concentration made a non-toxic, porous structure with tensile strength and elastic modulus in the range of human trachea, facilitating the chondrocyte proliferation. The results of 21-day cell culture indicated that glycosaminoglycans content was significantly higher for the rate of 2°C/min (12.04 µg/min) rather than the other (9.6 µg/min). Conclusion A homogenous porous structure was created by freeze drying. This allows the fabrication of a chitosan silk scaffold cross-linked by GA for cartilage tissue regeneration with application in tracheal regeneration.

Abstract
This in vitro study investigated the metabolism of human osteoarthritic (OA) chondrocytes encapsulated in a spherical matrix enriched of chitosan. Human OA chondrocytes were encapsulated and cultured for 28 days either in chitosan-alginate beads or in alginate beads. The beads were formed by slowly passing dropwise either the chitosan 0.6%-alginate 1.2% or the alginate 1.2% solution through a syringe into a 102 mM CaCl2 solution. Beads were analyzed histologically after 28 days. Interleukin (IL)-6 and -8, prostaglandin (PG) E2, matrix metalloproteinases (MMPs), hyaluronan and aggrecan were quantified directly in the culture supernatant by specific ELISA and nitric oxide (NO) by using a colorimetric method based on the Griess reaction. Hematoxylin and eosin staining showed that chitosan was homogeneously distributed through the matrix and was in direct contact with chondrocytes. The production of IL-6, IL-8 and MMP-3 by chondrocytes significantly decreased in chitosan-alginate beads compared to alginate beads. PGE2 and NO decreased also significantly but only during the first three days of culture. Hyaluronan and aggrecan production tended to increase in chitosan-alginate beads after 28 days of culture. Chitosan-alginate beads reduced the production of inflammatory and catabolic mediators by OA chondrocytes and tended to stimulate the synthesis of cartilage matrix components. These particular effects indicate that chitosan-alginate beads are an interesting scaffold for chondrocytes encapsulation before transplantation to repair cartilage defects.

Abstract
Cell therapy of the degenerated intervertebral disc is limited by the lack of appropriate cell sources, thus new strategies for the differentiation of stem cells towards a nucleus pulposus (NP)-like phenotype need investigation. In the current study, it is hypothesized that spherical niche-like structures composed of type II collagen and hyaluronan (HA) mimic the NP microenvironment and promote the differentiation of adipose-derived stem cells (ADSCs) towards an NP-like phenotype. ADSCs are embedded in microgels of different concentrations of collagen II/HA. Cells' response to the different environments is studied by characterizing differences in cells' viability, morphology, and gene expression. After 21 days of culture, ADSCs maintain ± 80% viability in all the conditions tested. Moreover, microgels with higher concentration of collagen are stable and maintain cells in a rounder shape. In presence of differentiation media, cells are able to differentiate in all the conditions tested, but in a more pronounced manner in the microgel with a higher concentration of collagen. By tuning microgels' properties, it is possible to influence ADSCs' phenotype and ability to differentiate. Indeed, when cultured in high concentrations of collagen, ADSCs expresses high levels of collagen II, aggrecan, SOX9, and low levels of collagen I.

Abstract
OBJECTIVE This study aimed to evaluate the structural benefit of a new biomaterial composed of alginate-chitosan (AC) beads dispersed in a hydrogel (H) derived from chitosan on the development of osteoarthritis (OA) in rabbit. DESIGN OA was induced by the surgical transection of the anterior cruciate ligament in rabbits. Animals received a single intra-articular injection (900 μl) of AC beads in H hydrogel, H hydrogel alone or saline a week after surgery. OA development was followed by X-rays. Blood samples were collected throughout the study to measure biological markers (Prostaglandins E2 - PGE2 and C reactive protein - CRP). Macroscopic observation and histological evaluation of articular cartilage and synovial membrane were performed 6 weeks after surgery. RESULTS AC beads in H hydrogel prevented from the development of OA based on the reduction of the Kellgren & Lawrence (K&L) score. It also significantly reduced the histological score of cartilage lesion severity. This effect was homogenous on every joint compartment. It was due to a significant effect on cartilage structure and cellularity scores. The injection of AC beads in H hydrogel also tended to reduce the synovial membrane inflammation. No significant variation of biological markers was noted. CONCLUSIONS The present pilot study provides interesting and promising results for the use of AC beads in H hydrogel in animal. It indeed prevented the development of OA cartilage lesions without inflammatory signs. The potencies of this biomaterial to protect OA joint should be further documented. It could then represent a new alternative for viscosupplementation in human OA management.

In vitro generation of osteochondral differentiation of human marrow mesenchymal stem cells in novel collagen-hydroxyapatite layered scaffolds. Acta Biomater 2011; 7:3999-4006.

Abstract
Integrated, layered osteochondral (OC) composite materials and/or engineered OC grafts are considered as promising strategies for the treatment of OC damage. A novel biomimetic collagen-hydroxyapatite (COL-HA) OC scaffold with different integrated layers has been generated by freeze-drying. The capacity of the upper COL layer and the lower COL/HA layer to promote the growth and differentiation of human mesenchymal stem cells (hMSCs) into chondrocytes and osteoblasts respectively was evaluated. Cell viability and proliferation on COL and COL/HA scaffolds were assessed by the MTT test. The chondrogenic differentiation of hMSCs on both scaffolds was evaluated by glucosaminoglycan (GAG) quantification, alcian blue staining, type II collagen immunocytochemistry assay and real-time polymerase chain reaction in chondrogenic medium for 21 days. Osteogenic differentiation was evaluated by alkaline phosphatase activity assay, type I collagen immunocytochemistry staining, alizarin S staining and mRNA expression of osteogenic gene for 14 days in osteogenic medium. The results indicated that hMSCs on both COL and COL/HA scaffolds were viable and able to proliferate over time. The COL layer was more efficient in inducing hMSC chondrogenic differentiation than the COL/HA layer, while the COL/HA layer possessed the superiority on promoting hMSC osteogenic induction over either COL layer or pure HA. In conclusion, the layered OC composite materials can effectively promote cartilage and bone tissue generation in vitro and are potentially usable for OC tissue engineering.

Abstract
The use of cell-scaffold constructs is a promising tissue engineering approach to repair cartilage defects and to study cartilaginous tissue formation. In this study, silk fibroin/chitosan blended scaffolds were fabricated and studied for cartilage tissue engineering. Silk fibroin served as a substrate for cell adhesion and proliferation while chitosan has a structure similar to that of glycosaminoglycans, and shows promise for cartilage repair. We compared the formation of cartilaginous tissue in silk fibroin/chitosan blended scaffolds seeded with bovine chondrocytes and cultured in vitro for 2 weeks. The constructs were analyzed for cell viability, histology, extracellular matrix components glycosaminoglycan and collagen types I and II, and biomechanical properties. Silk fibroin/chitosan scaffolds supported cell attachment and growth, and chondrogenic phenotype as indicated by Alcian Blue histochemistry and relative expression of type II versus type I collagen. Glycosaminoglycan and collagen accumulated in all the scaffolds and was highest in the silk fibroin/chitosan (1:1) blended scaffolds. Static and dynamic stiffness at high frequencies was higher in cell-seeded constructs than non-seeded controls. The results suggest that silk/chitosan scaffolds may be a useful alternative to synthetic cell scaffolds for cartilage tissue engineering.

Abstract
Despite the many advances in tissue engineering approaches, scientists still face significant challenges in trying to repair and replace soft tissues. Nature-inspired routes involving the creation of polymer-based systems of natural origins constitute an interesting alternative route to produce novel materials. The interest in these materials comes from the possibility of constructing multi-component systems that can be manipulated by composition allowing one to mimic the tissue environment required for the cellular regeneration of soft tissues. For this purpose, factors such as the design, choice, and compatibility of the polymers are considered to be key factors for successful strategies in soft tissue regeneration. More recently, polysaccharide-protein based systems have being increasingly studied and proposed for the treatment of soft tissues. The characteristics, properties, and compatibility of the resulting materials investigated in the last 10 years, as well as commercially available matrices or those currently under investigation are the subject matter of this review.

Abstract
Injury of articular cartilage due to trauma or pathological conditions is the major cause of disability worldwide, especially in North America. The increasing number of patients suffering from joint-related conditions leads to a concomitant increase in the economic burden. In this review article, we focus on strategies to repair and replace knee joint cartilage, since knee-associated disabilities are more prevalent than any other joint. Because of inadequacies associated with widely used approaches, the orthopedic community has an increasing tendency to develop biological strategies, which include transplantation of autologous (i.e., mosaicplasty) or allogeneic osteochondral grafts, autologous chondrocytes (autologous chondrocyte transplantation), or tissue-engineered cartilage substitutes. Tissue-engineered cartilage constructs represent a highly promising treatment option for knee injury as they mimic the biomechanical environment of the native cartilage and have superior integration capabilities. Currently, a wide range of tissue-engineering-based strategies are established and investigated clinically as an alternative to the routinely used techniques (i.e., knee replacement and autologous chondrocyte transplantation). Tissue-engineering-based strategies include implantation of autologous chondrocytes in combination with collagen I, collagen I/III (matrix-induced autologous chondrocyte implantation), HYAFF 11 (Hyalograft C), and fibrin glue (Tissucol) or implantation of minced cartilage in combination with copolymers of polyglycolic acid along with polycaprolactone (cartilage autograft implantation system), and fibrin glue (DeNovo NT graft). Tissue-engineered cartilage replacements show better clinical outcomes in the short term, and with advances that have been made in orthopedics they can be introduced arthroscopically in a minimally invasive fashion. Thus, the future is bright for this innovative approach to restore function.

Abstract
Systematic variation of solution conditions reveals that the elastic modulus (E) of individual collagen fibrils can be varied over a range of 2-200 MPa. Nanoindentation of reconstituted bovine Achilles tendon fibrils by atomic force microscopy (AFM) under different aqueous and ethanol environments was carried out. Titration of monovalent salts up to a concentration of 1 M at pH 7 causes E to increase from 2 to 5 MPa. This stiffening effect is more pronounced at lower pH where, at pH 5, e.g., there is an approximately 7-fold increase in modulus on addition of 1 M KCl. An even larger increase in modulus, up to approximately 200 MPa, can be achieved by using increasing concentrations of ethanol. Taken together, these results indicate that there are a number of intermolecular forces between tropocollagen monomers that govern the elastic response. These include hydration forces and hydrogen bonding, ion pairs, and possibly the hydrophobic effect. Tuning of the relative strengths of these forces allows rational tuning of the elastic modulus of the fibrils.

Abstract
Fetal bovine serum (FBS) has been reported to affect chondrocyte biosynthesis in monolayer culture. Insulin-Transferrin-Selenium (ITS) was investigated as a partial replacement for FBS during in vitro culture of rabbit articular chondrocytes in three-dimensional alginate scaffold. Chondrocyte-seeded alginate hydrogels were cultured in Dulbecco's modified Eagle's medium plus 10% FBS, 1% ITS plus 2% FBS, 1% ITS plus 4% FBS, or 1% ITS plus 8% FBS. At designed time point, the Chondrocyte-seeded alginate hydrogels were harvested and evaluated with histological staining, immunohistochemistry, and quantitative gene expression analysis. Viable cell density and cell division were also evaluated. Chondrocytes biosynthesis and cell division in 1% ITS with 2% FBS medium were similar to that in medium added with 10% FBS. For a total culture of 3 weeks, phenotypic gene expression in chondrocyte-seeded hydrogels was maintained at high levels in medium with 1% ITS plus 2% FBS, while it was decreased to varying degrees in the other groups. In conclusion, with 1% ITS, medium with 2% FBS could promote chondrocyte biosynthesis and cell division, and prevented cell dedifferentiation in three-dimensional alginate scaffolds.

Abstract
This article provides an up-to-date review on the applications of natural polymers, i.e., proteins, as materials for tissue engineering. Proteins are one of the important candidates for tissue engineering materials based on their superior biocompatibility, biodegradation, bioresorbability, and so on. However, their inferior mechanical properties limit their broad application. Currently-available proteins for application in tissue engineering or drug delivery systems, such as fibrin, collagen, zein, silk fibroin, keratin, casein and albumin, and the biodegradation of tissue-engineered substitutes based on proteins are presented. Techniques of scaffold fabrication are also mentioned. Problems and future possibilities for development of protein-based tissue-engineered substitutes are also introduced in this review.

Abstract
The gelatin-based haemostyptic compound Spongostan was tested as a three-dimensional (3D) chondrocyte matrix in an in vitro model for autologous chondrocyte transplantation using cells harvested from bovine knees. In a control experiment of monolayer cultures, the proliferation or de-differentiation of bovine chondrocytes was either not or only marginally influenced by the presence of Spongostan (0.3 mg/ml). In monolayers and 3-D Minusheet culture chambers, the cartilage-specific differentiation markers aggrecan and type-II collagen were ubiquitously present in a cell-associated fashion and in the pericellular matrix. The Minusheet cultures usually showed a markedly higher mRNA expression than monolayer cultures irrespective of whether Spongostan had been present or not during culture. Although the de-differentiation marker type-I collagen was also present, the ratio of type-I to type-II collagen or aggrecan to type-I collagen remained higher in Minusheet 3-D cultures than in monolayer cultures irrespective of whether Spongostan had been included in or excluded from the monolayer cultures. The concentration of GAG in Minusheet cultures reached its maximum after 14 days with a mean of 0.83 ± 0.8 μg/106 cells; mean ±, sem, but remained considerably lower than in monolayer cultures with/without Spongostan. Our results suggest that Spongostan is in principle suitable as a 3-D chondrocyte matrix, as demonstrated in Minusheet chambers, in particular for a culture period of 14 days. Clinically, differentiating effects on chondrocytes, simple handling and optimal formability may render Spongostan an attractive 3-D scaffold for autologous chondrocyte transplantation.

Abstract
Given the inadequacies of existing repair strategies for cartilage injuries, tissue engineering approach using biomaterials and stem cells offers new hope for better treatments. Recently, we have fabricated injectable collagen-human mesenchymal stem cell (hMSC) microspheres using microencapsulation. Apart from providing a protective matrix for cell delivery, the collagen microspheres may also act as a bio-mimetic matrix facilitating the functional remodeling of hMSCs. In this study, whether the encapsulated hMSCs can be pre-differentiated into chondrogenic phenotype prior to implantation has been investigated. The effects of cell seeding density and collagen concentration on the chondrogenic differentiation potential of hMSCs have been studied. An in vivo implantation study has also been conducted. Fabrication of cartilage-like tissue micro-masses was demonstrated by positive immunohistochemical staining for cartilage-specific extracellular matrix components including type II collagen and aggrecan. The meshwork of collagen fibers was remodeled into a highly ordered microstructure, characterized by thick and parallel bundles, upon differentiation. Higher cell seeding density and higher collagen concentration favored the chondrogenic differentiation of hMSCs, yielding increased matrix production and mechanical strength of the micro-masses. These micro-masses were also demonstrated to integrate well with the host tissue in NOD/SCID mice.

Abstract
Colominic acid (CA) is a homopolymer of sialic acid residues and is solely composed of polymerised units of alpha-2,8-linked N-acetylneuraminic acid. CA is a specific derivative of polysialic acid (PSA), produced as the capsular polysaccharide of Escherichia coli K1 derived molecule of PSA. PSA in vivo plays a significant role in synaptic plasticity and neural development. The use of collagen materials doped with defined CA is presented for the cultivation of various cell lines relevant for possible applications in Tissue Engineering. First, the release behaviour under culture conditions of the collagen-based (C-CA) materials was investigated by thiobarbituric acid assay. Additionally, the established cell lines, PC-12 and immortalised Schwann cells (ISC), used for neurobiological and neurochemical studies and the model liver cell line Hep-G2 as indicator for biocompatibility testing, were cultured on the C-CA matrix. Cell proliferation (MTT-test) and cell adhesion (DAPI-staining) of the cell lines on the matrices were observed. Likewise, gene expression of the marker genes thyrosine hydroxylase for the PC-12 cells, and albumin, transferrin and CYP3A4 for the Hep-G2 cells was evaluated via RT-PCR. The results indicate that CA integration in established biomaterial constructs enhances cell proliferation and offers promising features as conduits additive in regarding peripheral nerve regeneration.

Abstract
The use of three-dimensional biodegradable matrices is one major issue in tissue engineering. Numerous materials, fabrication techniques, and modifications have been used and tested in different areas of tissue engineering recently. But nevertheless, technology is far from being optimized and optimal constructs with bioidentical and mechanical properties have not been described in the literature so far. Hence, there is great demand of new suitable biomaterials for tissue engineering applications. In this study, a fast and efficient screening system for initial testing of biomaterials for cell culture application was developed. The set up for the screening system and the decision criteria applied for the determination of suitability of new materials are presented. Hep-G2 and PC-12 cells were seeded onto different matrices and cultured over a period of 2 weeks. The viability of the cells was monitored via the MTT assay. Cell spreading was investigated by DAPI-staining of cell nuclei. Furthermore, the adhesion of the cells on the different matrices was examined by counting the number of attached cells. With these general assays a classification of materials is possible with regard to their suitability. Optimal cell models must be chosen for the defined applications and at least two cell lines are necessary for a differentiating interpretation.

Abstract
This study describes the development and application of a novel strategy to tissue engineer musculoskeletal cartilages with human embryonic stem cells (hESCs). This work expands the presently limited understanding of how to chondrogenically differentiate hESCs through the use of chondrogenic medium alone (CM) or CM with two growth factor regimens: transforming growth factor (TGF)-beta3 followed by TGF-beta1 plus insulin-like growth factor (IGF)-I or TGF-beta3 followed by bone morphogenic protein (BMP)-2. It also extends the use of the resulting chondrogenically differentiated cells for cartilage tissue engineering through a scaffoldless approach called self-assembly, which was conducted in two modes: with (a) embryoid bodies (EBs) or (b) a suspension of cells enzymatically dissociated from the EBs. Cells from two of the differentiation conditions (CM alone and TGF-beta3 followed by BMP-2) produced fibrocartilage-like constructs with high collagen I content, low collagen II content, relatively high total collagen content (up to 24% by dry weight), low sulfated glycosaminoglycan content (approximately 4% by dry weight), and tensile properties on the order of megapascals. In contrast, hESCs treated with TGF-beta3 followed by TGF-beta1 + IGF-I produced constructs with no collagen I. Results demonstrated significant differences among the differentiation conditions in terms of other biochemical and biomechanical properties of the self-assembled constructs, suggesting that distinct growth factor regimens differentially modulate the potential of the cells to produce cartilage. Furthermore, this work shows that self-assembly of cells obtained by enzymatic dissociation of EBs is superior to self-assembly of EBs. Overall, the results of this study raise the possibility of manipulating the characteristics of hESC-generated tissue toward specific musculoskeletal cartilage applications.
