Bone Morphogenic Protein 7

Alginate-poloxamer (ALG-POL) copolymer with optimal POL content was synthesized, and it was combined with silk fibroin (SF) for building ALG-POL/SF dual network hydrogels. Hyaluronic acid(HA)/chitosan-poly(dioxanone)(CH-PDO) complex nanoparticles (NPs) with optimized composition and high encapsulation efficiency were employed as a vehicle for loading bone morphogenic protein-7 (BMP-7). BMP-7-loaded HA/CH-PDO NPs were incorporated into ALG-POL/SF hydrogel for constructing composite gels to achieve controlled release of BMP-7. These gels showed thermosensitive sol-gel transitions near physiological temperature and pH; and they were tested to be elastic, tough and strong. Some gels exhibited abilities to administer the BMP-7 release in nearly linear manners for a few weeks. Synovium-derived mesenchymal stem cells (SMSCs) were seeded into optimally fabricated gels for assessing their chondrogenic differentiation potency. Real-time PCR analyses showed that the blank ALG-POL/SF gels were not able to induce the chondrogenic differentiation of SMSCs, whereas SMSCs were detected to significantly express cartilage-related genes once they were seeded in the BMP-7-loaded ALG-POL/SF gel for two weeks. The synthesis of cartilaginous matrix components further confirmed that SMSCs seeded in the BMP-7-loaded ALG-POL/SF gel differentiated toward chondrogenesis. Results suggest that BMP-7-loaded ALG-POL/SF composite gels can function as a promising biomaterial for cartilage tissue engineering applications.

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.

There is a great need for bioengineered cartilage because of the lack of medical or surgical therapies to improve articular cartilage healing. We hypothesised that porcine adipose-derived stem cells (pASC) can be induced to undergo chondrogenic differentiation within hyaluronic acid (HA) hydrogels. The objective of this study was to develop UV-curable pASC-laden HA hydrogels aimed at application in cartilage tissue engineering. HA was treated with glycidyl methacrylate (GM) to allow chemical gelation of the polymer upon exposure to UV light. 2% HAGM hydrogel was obtained by mixing HAGM with chondrogenic medium consisting of TGFβ, ascorbic acid, ITS+ premix (insulin, transferrin, selenous acid; Cat. No. 354352, BD Biosciences, Franklin Lakes, NJ), sodium pyruvate, and dexamethasone. Passage three-pASC were resuspended in 2% HAGM hydrogel with 2 × 107 cells mL–1. Twelve-and-one-half (12.5)-μL droplets (micromasses) of this suspension containing 250 000 pASC were placed in 24-well culture plates and incubated for 2 h at 37°C and 5% CO2 to allow for cell attachment. Subsequently, the cell-laden hydrogels were cured with ~10 mW cm–2 365-nm UV light for 10 min, covered with 500 μL of chondrogenic medium, and cultured for up to 11 days at 37°C and 5% CO2. Additionally, pASC micromasses were cultured in chondrogenic medium without loading on 2% HAGM hydrogels as positive controls, and in non-chondrogenic DMEM as negative controls. Samples were collected at 4, 7, and 11 days in to culture for cryopreservation (for immunohistochemistry; IHC) and dimethylmethylene blue (DMMB) assay. IHC on day 11 of culture demonstrated the expression of cartilage specific proteins type-II collagen and aggrecan. On the basis of data from the DMMB assay, chondrogenic differentiation of pASC-laden micromasses in positive controls and 2% HAGM treatments were not different (P > 0.05). This indicates that ASC can produce cartilage equally well under both conditions, supporting the idea that HAGM may be used as a matrix for cartilage formation in vitro and possibly in vivo. In conclusion, using a micromass cell culture system, we demonstrated that 2% HAGM hydrogels support proliferation and chondrogenic differentiation of pASC. Further experiments testing different concentrations of HAGM and UV exposure levels, and larger sample numbers are warranted to further improve this procedure.

Cell Type

Mesenchymal stem cells (MSCs) are an attractive cell type for cartilage tissue engineering in that they can undergo chondrogenesis in a variety of 3D contexts [1]. Focused efforts in MSC-based cartilage tissue engineering have recently culminated in the formation of biologic materials possessing biochemical and functional mechanical properties that match that of the native tissue [2]. These approaches generally involve the continuous or intermittent application of pro-chondrogenic growth factors during in vitro culture. For example, in one recent study, we showed robust construct maturation in MSC-seeded hyaluronic acid (HA) hydrogels transiently exposed to high levels of TGF-β3 [3]. Despite the promise of this approach, MSCs are a multipotent cell type and retain a predilection towards hypertrophic phenotypic conversion (i.e., bone formation) when removed from a pro-chondrogenic environment (e.g., in vivo implantation). Indeed, even in a chondrogenic environment, many MSC-based cultures express pre-hypertrophic markers, including type X collagen, MMP13, and alkaline phosphatase [4]. To address this issue, recent studies have investigated co-culture of human articular chondrocytes and MSCs in both pellet and hydrogel environments. Chondrocytes appear to enhance the initial efficiency of MSC chondrogenic conversion, as well as limit hypertrophic changes in some instances (potentially via secretion of PTHrP and/or other factors) [5–7]. While these findings are intriguing, articular cartilage has a unique depth-dependent morphology including zonal differences in chondrocyte identity. Ng et al. showed that zonal chondrocytes seeded in a bi-layered agarose hydrogel construct can recreate depth-dependent cellular and mechanical heterogeneity, suggesting that these identities are retained with transfer to 3D culture systems [8]. Further, Cheng et al. showed that differences in matrix accumulation and hypertrophy in zonal chondrocytes was controlled by bone morphogenic protein [9]. To determine whether differences in zonal chondrocyte identity influences MSC fate decisions, we evaluated functional properties and phenotypic stability in photocrosslinked hyaluronic acid (HA) hydrogels using distinct, zonal chondrocyte cell fractions co-cultured with bone marrow derived MSCs.

Cartilage tissue engineering is a promising treatment for damaged or diseased cartilage that requires thorough understanding of influential parameters involved in chondrogenic differentiation. This study examined how 4-h application of cyclic hydrostatic pressure (CHP) of 5 MPa at 0.5 Hz could modulate chondroinduction of human adipose-derived mesenchymal stem cells (hAMSCs) in vitro. Four groups were examined including a negative control group, a chemical group treated by growth factor for 10 days, a mechanical group exposed to 4-h loading on the 10th day of pellet culture without any chondrogenic stimulator, and finally a chemical-mechanical group subjected to both growth factor and loading. Application of cyclic hydrostatic pressure increased the expression of chondrogenic genes, including sox9 and aggrecan to higher levels than those of the chemical group. This study indicates that cyclic hydrostatic pressure initiates and enhances the chondrogenic differentiation of mesenchymal stem cells with or without growth factors in vitro and confirms the important role of hydrostatic pressure during chondrogenesis in vivo.
