Abstract
Tissue Engineering of cartilage has been hampered by the inability of engineered tissue to express native levels of type II collagen in vitro. Inadequate levels of type II collagen are, in part, due to a failure to recapitulate the physiological environment in culture. In this study, we engineered primary rabbit chondrocytes to express a secreted reporter, Gaussia Luciferase, driven by the type II collagen promoter, and applied a Design of Experiments approach to assess chondrogenic differentiation in micronutrient-supplemented medium. Using a Response Surface Model, 240 combinations of micronutrients absent in standard chondrogenic differentiation medium, were screened and assessed for type II collagen promoter-driven Gaussia luciferase expression. While the target of this study was to establish a combination of all micronutrients, alpha-linolenic acid, copper, cobalt, chromium, manganese, molybdenum, vitamins A, E, D and B7 were all found to have a significant effect on type II collagen promoter activity. Five conditions containing all micronutrients predicted to produce the greatest luciferase expression were selected for further study. Validation of these conditions in 3D aggregates identified an optimal condition for type II collagen promoter activity. Engineered cartilage grown in this condition, showed a 170% increase in type II collagen expression (Day 22 Luminescence) and in Young's tensile modulus compared to engineered cartilage in basal media alone.Collagen cross-linking analysis confirmed formation of type II-type II collagen and type II-type IX collagen cross-linked heteropolymeric fibrils, characteristic of mature native cartilage. Combining a Design of Experiments approach and secreted reporter cells in 3D aggregate culture enabled a high-throughput platform that can be used to identify more optimal physiological culture parameters for chondrogenesis.

Abstract
Clinical treatment of Osteoarthritis (OA) remains a challenge due to the poor self-regeneration ability of cartilage. Deer antler is the only cartilage tissue that can completely regenerate each year. Insulin-like growth factor 1 (IGF-1) is one of the major active components in the deer antler that participate in regulating the rapid regeneration of deer antler cartilage. This has led us to speculate that deer IGF-1 might potentially become a candidate drug for reducing damage and inflammation of OA. Thus, we aimed to explore the underlying mechanism of deer IGF-1 in chondrocyte proliferation, differentiation, and inflammation response. Deer, mouse, and human IGF-1 amino acid sequences and protein structures were aligned using CLUSTAL and PSIPRED. The underlying molecular mechanism of deer IGF-1 on primary chondrocytes was investigated by RNA-sequencing (RNA-seq) technology combined with various experiments. Cytokine interleukin-1β (IL-1β) was used to induce the inflammation response of primary chondrocytes. We found that deer IGF-1 was more similar to human IGF-1 than mouse IGF-1. qRT-PCR and immunofluorescence assay indicated that deer IGF-1 had stronger effects than mouse IGF-1. We also found that the deer IGF-1 enhanced the expression of cell proliferation, differentiation, and extracellular matrix (ECM)-related genes, but decreased the expression of ECM-degrading genes. Deer IGF-1 also attenuated the IL-1β-induced inflammatory and ECM degradation in chondrocytes. This study provides insight into the molecular mechanisms of deer IGF-1 on primary chondrocyte viability and presents a candidate for combatting inflammatory responses in OA development.

Abstract
Lameness is a leading cause of animal welfare and production concerns for the poultry industry as fast-growing, high-yielding broilers seem more susceptible to bone disease and infections. A major limitation to the study of these disorders is the lack of a chicken immortalized chondrocyte cell. Primary cell isolation is a valid and complex method for establishing a relevant in vitro model for diseases. In this study, isolation and high-density culturing of primary chondrocytes form 1-d old chicks was followed by confirmation of cell type, identification of optimal phenotypic expression, and evaluation of cells functionality. mRNA expression, as well as protein production and secretion, of COLI, COLII, Sox9, ACAN, and COLXA1 on day 3 (d3), d7, d11, d14, d18, and d21 in culture showed that avian growth plate chondrocytes under these conditions exhibit optimal phenotypes from d3 to d7. This is evident by a shift from COLII dominant expression in early-culture to COLI dominant expression by late-culture in conjunction with a loss of other chondrocyte markers Sox9, ACAN, and COLXA1. Additionally, morphological changes seen through live cell imaging coincide with the shift of phenotype in mid- to late-culture periods indicating a dedifferentiated phenotype. The functionality of the cultured cells was confirmed using Brefeldin-A treatment which significantly reduced secretion of COLII by d7 chondrocytes. These results provide a foundation for future research utilizing avian primary chondrocytes with optimal phenotypes for disease modeling or passaging.
