(Submitter supplied) Articular and growth plate cartilage have comparable structures consisting of three distinct layers of chondrocytes, suggesting similar differentiation programs and therefore similar gene expression profiles. To address this hypothesis and to explore transcriptional changes that occur during the onset of articular and growth plate cartilage divergence, we used microdissection of 10-day-old rat proximal tibial epiphyses, microarray analysis, and bioinformatics to compare gene expression profiles in individual layers of articular and growth plate cartilage. more...

(Submitter supplied) We used laser capture microdissection to isolate different zones of the articular cartilage from proximal tibiae of 1-week old mice, and used microarray to analyze global gene expression. Bioinformatic analysis corroborated previously known signaling pathways, such as Wnt and Bmp signaling, and implicated novel pathways, such as ephrin and integrin signaling, for spatially associated articular chondrocyte differentiation and proliferation. more...

(Submitter supplied) We set out to generate transcriptional maps of chondrocyte UPR gene networks in vivo using two mouse models (Schmid and Cog) of Schmid chondrodysplasia, in order to define the consequences of UPR activation for the adaptation, differentiation, and survival of chondrocytes experiencing ER stress during hypertrophy, thus providing insights into ER stress signaling and its impact on cartilage pathophysiology. more...

(Submitter supplied) Using a conditional inactivation approach in the mouse, we examined the importance of SOX9 in adult growth plate and articular cartilage. We specifically investigated the roles of SOX9 in the expression of the pancartilaginous, growth-plate and articular programs and in maintaining the chondrocyte lineage fate.

(Submitter supplied) To explore the mechanisms responsible for spatial and temporal regulation of the growth plate, we microdissected postnatal rat growth plates into their constituent zones and then used microarray analysis to characterize the changes in gene expression that occur as chondrocytes undergo spatially-associated differentiation and temporally-associated senescence.

(Submitter supplied) In the growth plate, the reserve and perichondral zones have been hypothesized to have similar functions, but their exact functions are poorly understood. Our hypothesis was that significant differential gene expression exists between perichondral and reserve chondrocytes that may differentiate the respective functions of these two zones. Normal Sprague-Dawley rat growth plate chondrocytes from the perichondral zone (PC), reserve zone (RZ), proliferative zone (PZ), and hypertrophic zone (HZ) were isolated by laser microdissection and then subjected to microarray analysis. more...

(Submitter supplied) The aim of the current study was to identify molecular markers for articular cartilage that can be used for the quality control of tissue engineered cartilage. Therefore a genom-wide expression analysis was performed using RNA isolated from articular and growth plate cartilage, both extracted from the knee joints of minipigs.

(Submitter supplied) Mandibular condylar cartilage (MCC) has many distinctive features reviewed in the literature, hence it would be expected that the genetic regulation of the biological process in the MCC to be different from those of other articular hyaline cartilages and epiphyseal growth cartilages. In addition, The MCC is a multi-zonal fibrocartilage containing different types of cells, which are well characterized histomorphologically, but the factors governing their morphological transition across the zones are not fully understood. more...

(Submitter supplied) We used human fetal bone marrow-derived mesenchymal stromal cells (hfMSCs) differentiating towards chondrocytes as an alternative model for the human growth plate (GP). Our aims were to study gene expression patterns associated with chondrogenic differentiation to assess whether chondrocytes derived from hfMSCs are a suitable model for studying the development and maturation of the GP. hfMSCs efficiently formed hyaline cartilage in a pellet culture in the presence of TGFB3 and BMP6. more...

(Submitter supplied) Chondrocytes are subject to continuous loads placed upon them throughout development and physical activity. Normal physiological loads enable the maintenance of the articular cartilage health, however abnormal loads contribute to pathological joint ageing. Similarly, the growth plate cartilage is exposed to a number of loads during growth and development. Due to the high-water content of cartilage, hydrostatic pressure is considered one of the main biomechanical influences on chondrocytes and it plays an important role in the mechanoregulation of cartilage. more...
