Abstract
Meniscus injuries are very common and still pose a challenge for the orthopedic surgeon. Meniscus injuries in the inner two-thirds of the meniscus remain incurable. Tissue-engineered meniscus strategies seem to offer a new approach for treating meniscus injuries with a combination of seed cells, scaffolds, and biochemical or biomechanical stimulation. Cell- or scaffold-based strategies play a pivotal role in meniscus regeneration. Similarly, biochemical and biomechanical stimulation are also important. Seed cells and scaffolds can be used to construct a tissue-engineered tissue; however, stimulation to enhance tissue maturation and remodeling is still needed. Such stimulation can be biomechanical or biochemical, but this review focuses only on biochemical stimulation. Growth factors (GFs) are one of the most important forms of biochemical stimulation. Frequently used GFs always play a critical role in normal limb development and growth. Further understanding of the functional mechanism of GFs will help scientists to design the best therapy strategies. In this review, we summarize some of the most important GFs in tissue-engineered menisci, as well as other types of biological stimulation.

Abstract
Background Treatment strategies for meniscal injury are shifting from meniscectomy to repair, especially cell-based therapy. Delivering selected genes to donor cells can modify differentiation and proliferation. Efficiency of gene transfection and expression may relate to cell type. Material/Methods Full-length hIGF-1 cDNA was cloned into eukaryotic expression vector by PCR. Human BMSCs and meniscal fibrochondrocytes were isolated and cultured in vitro and hIGF-1 gene was transfected by FuGene 6. Expression of EGFP and hIGF-1 were determined. Biological activity of the hIGF-1 in medium was assessed by MTT chromatometry. Real-time quantitative PCR and Western blot were used to assess the expression of exogenous genes. Efficacy of gene transfection was detected by immunohistochemistry staining and flow cytometry. Results Sequences of hIGF-1 were verified by sequence analysis. Expression of EGFP increased gradually and reached peak intensity 48 h after transfection. Transfection efficiency of BMSCs was higher than meniscal fibrochondrocytes. The population doubling time was decreased in both cell types. Peak concentration of hIGF-1 in the medium of BMSCs and meniscal cells was 32.5±4.8 ng/ml and 24.5±4.6 ng/ml, respectively. Secreted hIGF-1 possessed the ability to enhance proliferation of the cell line. Results of qPCR and Western blot confirmed the expression of hIGF-1. Type II collagen appeared within the cells, and percentage of cells in S stage was increased in both cell types after transfection. Conclusions hIGF-1 cDNA can be transfected into BMSCs and meniscal fibrochondrocytes, resulting in gene expression. Expression efficiency in BMSCs was higher than that in fibrochondrocytes.

Abstract
Vascular tissue engineering relies on the combination of patient-derived cells and biomaterials to create new vessels. For clinical application, data regarding the function and behavior of patient-derived cells are needed. We investigated cell growth and functional characteristics of human venous endothelial cells (HVECs) from coronary arterial bypass graft (CABG), chronic kidney disease (CKD), and control patients. HVECs were isolated from venous specimens that were obtained during elective surgical procedures by means of collagenase digestion. Gene expression, proliferation, migration, secretory functions, and thrombogenic characteristics were evaluated using high-throughput assays. A total of 48 cell batches (14 control, 19 CABG, and 15 CKD subjects) were assessed. Proliferation, population doubling times, and migration of HVECs derived from CABG and CKD patients did not differ from controls. Thrombomodulin expression was higher in CABG-HVECs compared with controls. HVEC-induced thrombin formation in plasma did not differ between groups, and the contact activation pathway was the major contributor to coagulation. Patient-derived HVECs were able to attach and survive on polycaprolactone scaffolds that were coated with fibrin. HVECs from cardiovascular-diseased and CKD patients showed comparable functional characteristics with HVECs derived from uncompromised patients. We, therefore, conclude that endothelial cells from aged patients with comorbidities can be safely used for isolation and in vitro expansion for vascular tissue engineering.

Abstract
Osteochondral defects in weight-bearing regions must be repaired with cartilage and subchondral bone support simultaneously, as well as the integration between the 2, particularly in young, active patients. In this study, a new method called mix-mosaicplasty was used to reconstruct large osteochondral defects (6-mm diameter) in the weight-bearing region of the femoral condyle of goats. Two periosteum-bone plugs and 1 osteochondral plug harvested from the proximal tibia and intertrochlea groove were assembled to fill the defects in a mosaic mode. The goats were euthanized 16 weeks postoperatively, and the result of the repair process was assessed using macroscopy, morphologic analysis, electron microscope observation, glycosaminoglycan assay, and magnetic resonance imaging. Sixteen weeks postoperatively, the superficial surface of the defective region was covered with regenerated cartilage, and the periosteum-bone plugs were combined with each other. However, cleavage between cartilage plugs was noted. The donor site, which was filled with periosteum-bone plugs, was regenerated with fibrocartilage-like tissue. The repaired tissue was composed of small chondrocyte-like cells arranged tightly within an evenly distributed extracellular matrix containing type II collagen. Cells of the regenerated tissue in periosteum-bone plugs were smaller and distributed more densely. Electron microscopy demonstrated regular matrix fibers and abundant organelles within the repaired tissue. No significant differences of glycosaminoglycan content were observed between reconstructed tissue and normal hyaline cartilage. Magnetic resonance imaging revealed the healing process between plugs other than the control group. The new technique of mix-mosaicplasty can reconstruct full-thickness osteochondral compound defects in the weight-bearing region of the femoral condyle.

Abstract
Articular cartilage defects do not regenerate. Transplantation of autologous articular chondrocytes, which is clinically being performed since several decades, laid the foundation for the transplantation of genetically modified cells, which may serve the dual role of providing a cell population capable of chondrogenesis and an additional stimulus for targeted articular cartilage repair. Experimental data generated so far have shown that genetically modified articular chondrocytes and mesenchymal stem cells (MSC) allow for sustained transgene expression when transplanted into articular cartilage defects in vivo. Overexpression of therapeutic factors enhances the structural features of the cartilaginous repair tissue. Combined overexpression of genes with complementary mechanisms of action is also feasible, holding promises for further enhancement of articular cartilage repair. Significant benefits have been also observed in preclinical animal models that are, in principle, more appropriate to the clinical situation. Finally, there is convincing proof of concept based on a phase I clinical gene therapy study in which transduced fibroblasts were injected into the metacarpophalangeal joints of patients without adverse events. To realize the full clinical potential of this approach, issues that need to be addressed include its safety, the choice of the ideal gene vector system allowing for a long-term transgene expression, the identification of the optimal therapeutic gene(s), the transplantation without or with supportive biomaterials, and the establishment of the optimal dose of modified cells. As safe techniques for generating genetically engineered articular chondrocytes and MSCs are available, they may eventually represent new avenues for improved cell-based therapies for articular cartilage repair. This, in turn, may provide an important step toward the unanswered question of articular cartilage regeneration.

Enhanced regeneration of the ligament-bone interface using a poly(L-lactide-co-ε-caprolactone) scaffold with local delivery of cells/BMP-2 using a heparin-based hydrogel. Acta Biomater 2011; 7:244-57.

Abstract
Recently, the ligament-bone (LTB) junction has been emphasized for the effective transmission of mechanical force and the reduction in stress concentration between the soft ligament and hard bone tissue. The aim of this study was to regenerate an integrated LTB interface by inoculating LTB-relevant cells, isolated from fibrocartilage (FC) or ligament (LIG), separately into each designated region in a single porous cylindrical PLCL scaffold. An injectable, heparin-based hydrogel that has proved to be effective in the culture of chondrocytes as well as the sustained release of growth factor was employed to locally deliver fibrochondrocytes and osteoinductive bone morphogenetic protein-2 (BMP-2) into the FC region, to promote FC regeneration. In in vitro experiments the hydrogel-combined FC systems produced significantly larger amounts of calcium and glycosaminoglycans (GAGs), but less collagen and DNA than FC samples without the hydrogel and all LIG samples. After in vivo subcutaneous implantation in mice for 8 weeks the secreted calcium and GAG contents of the hydrogel-containing FC samples were superior or similar to those of the in vitro hydrogel-containing FC samples at 6 weeks. As a result of the enhanced production of calcium and GAG, the in vivo hydrogel-containing FC samples produced the highest compressive modulus among all samples. Histological and immunofluorescence analysis as well as elemental analysis also confirmed a denser and more homogeneous distribution of calcium, GAG, osteocalcin and neovascularization marker in the in vitro/in vivo hydrogel-containing FC systems than those without hydrogel. These results also show the beneficial effects of BMP-2 added using the hydrogel. In summary, the use of a heparin-based hydrogel for the local delivery of fibrochondrocytes and BMP-2 could accelerate the maturation and differentiation of LTB-specific FC tissues, and it was also possible to recreate the unique stratification of calcified FC and LIG tissues in a single porous PLCL scaffold in terms of both biochemical and biomechanical properties.
