The pig is an ideal species for use in tissue engineering studies of bone and cartilage defect repair. Novel collagen-glycosaminoglycan hydrogel (CG) scaffolds have shown promise for supporting bone and cartilage growth from mesenchymal stem cells. In order to determine the suitability of these scaffolds for use in porcine models for bone and cartilage tissue engineering, we have begun to investigate the behaviour of porcine mesenchymal stem cells on this material. The purpose of this study was to determine if mesenchymal stem cells from fat (ASC) or bone marrow (BMSC) displayed better adherence and penetration into the CG scaffold material. The BMSC and ASC isolated from young adult Yorkshire pigs were cultured in DMEM with 10% fetal bovine serum. The ASC and BMSC were then trypsinized and used to seed ~3 mm diameter CG scaffolds with 140,000 cells/scaffold. Scaffolds were then cultured for 10 days by 3 different methods: roller culture, free-floating non-adherent dishes (floating), or attached to tissue culture-treated dishes (static). At the conclusion of the incubation period, the scaffold pieces were then fixed with 4% paraformaldehyde, embedded for cryosectioning, and sliced into 10 µm cryosections. Sections were stained for vimentin and 4’,6-diamidino-2-phenylindole (DAPI) to label cells. Stained sections were observed on a Leica DMB4200 microscope (Leica Microsystems, Wetzlar, Germany) and images acquired using ImagePro Plus software (Media Cybernetics Inc., Rockville, MD, USA). The DAPI-stained cells were counted to determine cell density and expressed as average number of nuclei per millimeter squared for each cell and culture type. Data were analysed by ANOVA utilising a post hoc Holm multiple comparison analysis. Samples from roller cultures did not display adhered cells for either BMSC or ASC. In contrast, floating and static culture allowed both ASC and BMSC to adhere to the scaffold and migrate to the centre of the scaffold equally well. However, significant differences in cell densities were noted between ASC and BMSC on CG scaffolds, with BMSC growing to higher densities than ASC in both floating and static culture. For floating cultures, BMSC-loaded scaffolds exhibited a cell density of 105.7 compared with 53.3 cells/mm2 for ASC (n = 4; P < 0.05). For static cultures, BMSC-loaded scaffolds exhibited a cell density of 128.3 compared with 36.8 cells/mm2 for ASC-loaded samples (n = 3; P < 0.01). Thus, BMSC grow to greater densities more rapidly than ASC and may be more efficient for use in forming bone and cartilage on these scaffolds. Current experiments underway will compare osteogenic and chondrogenic differentiation potential of ASC and BMSC on CG scaffolds, and will attempt to engineer osteochondral interface tissue on CG scaffolds from co-cultures of chondrocytes and stem cells.

The Impact

Defects in articular cartilage injury and chronic osteoarthritis are very widespread and common, and the ability of injured cartilage to repair itself is limited. Stem cell-based cartilage tissue engineering provides a promising therapeutic option for articular cartilage damage. However, the application of the technique is limited by the number, source, proliferation, and differentiation of stem cells. The co-culture of mesenchymal stem cells and chondrocytes is available for cartilage tissue engineering, and mechanical stimulation is an important factor that should not be ignored. A combination of these two approaches, i.e., co-culture of mesenchymal stem cells and chondrocytes under mechanical stimulation, can provide sufficient quantity and quality of cells for cartilage tissue engineering, and when combined with scaffold materials and cytokines, this approach ultimately achieves the purpose of cartilage repair and reconstruction. In this review, we focus on the effects of co-culture and mechanical stimulation on mesenchymal stem cells and chondrocytes for articular cartilage tissue engineering. An in-depth understanding of the impact of co-culture and mechanical stimulation of mesenchymal stem cells and chondrocytes can facilitate the development of additional strategies for articular cartilage tissue engineering.

Abstract Cartilage tissue engineering, particularly micropattern, can influence the biophysical properties of mesenchymal stem cells (MSCs) leading to chondrogenesis. In this research, human Wharton’s jelly MSCs (hWJ-MSCs) were grown on a striped micropattern containing spider silk protein (spidroin) from Argiope appensa. This research aims to direct hWJ-MSCs chondrogenesis using micropattern made of spidroin bioink as opposed to fibronectin that often used as the gold standard. Cells were cultured on striped micropattern of 500 µm and 1000 µm width sizes without chondrogenic differentiation medium for 21 days. The immunocytochemistry result showed that spidroin contains RGD sequences and facilitates cell adhesion via integrin β1. Chondrogenesis was observed through the expression of glycosaminoglycan, type II collagen, and SOX9. The result on glycosaminoglycan content proved that 1000 µm was the optimal width to support chondrogenesis. Spidroin micropattern induced significantly higher expression of SOX9 mRNA on day-21 and SOX9 protein was located inside the nucleus starting from day-7. COL2A1 mRNA of spidroin micropattern groups was downregulated on day-21 and collagen type II protein was detected starting from day-14. These results showed that spidroin micropattern enhances chondrogenic markers while maintains long-term upregulation of SOX9, and therefore has the potential as a new method for cartilage tissue engineering.
