Project description:Affymetrix Chicken Gene 1.0 ST Array (ChiGene-1_1-st) profiles were generated from growth plate cartilage derived from the distal femur and proximal tibia of embryonic chickens at three developmental stages (day 12, 13 and 15) corresponding to stages prior to and immediately after the acqusition of mechano-responsive cartilage growth in the femur but not tibia (which does not respond to mechanical stimuli until later stages). Additionally, array profiles were generated from growth plate cartilage from the distal femur and proximal tibia of E15 chicks which were pharmacologically immobilized by decamethonium bromide treatment, which reduces longitudinal growth of the femur only at this stage.

Project description:Expression data from articular and growth plate cartilage
| PRJNA131031 | ENA
Project description: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. Keywords: Native material or primary cells isolated from articular cartilage and growth plate cartilage

Project description:Relative expression levels of mRNAs in chicken cecal epithelia experimentally infected with Eimeria tenella were measured at 4.5 days post-infection. Two weeks old chickens were uninfected (negative control) or were orally inoculated with sporulated oocysts of Eimeria tenella. Cecal epithelia samples were collected from >12 birds in infected or uninfected group at 4.5 d following infections, in which samples from 4 birds were pooled together to form a total 3 biological replicates in each group. Parasite merozoites were also collected from four infected chickens at 5 d after infections. Uninfected control samples, merozoites and infection group samples were selected for RNA extraction and hybridization on Affymetrix microarrays. We used Affymetrix GeneChip chicken genome arrays to detail the chicken cecal epithelia gene expression in the control and E. tenella-infected birds.

Project description: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. We found that many genes that were spatially upregulated in intermediate/deep zone of articular cartilage were also spatially upregulated in resting zone of growth plate cartilage (overlap greater than expected by chance, P < 0.001). Interestingly, superficial zone of articular cartilage showed an expression profile with similarities to both proliferative and hypertrophic zones of growth plate cartilage (P < 0.001 each). Additionally, significant numbers of known proliferative zone markers (3 out of 6) and hypertrophic zone markers (27 out of 126) were spatially upregulated in superficial zone compared to intermediate/deep zone (more than expected by chance, P < 0.001 each). In conclusion, we provide evidence that intermediate/deep zone of articular cartilage has a gene expression profile more similar to resting zone of growth plate cartilage, whereas superficial zone has a gene expression profile more similar to proliferative and hypertrophic zones.

Keywords: Native material or primary cells isolated from articular cartilage and growth plate cartilage Articular and growth plate cartilage were taken for RNA extraction and hybridization on Affymetrix microarrays. Furthermore chondrocytes from each type of cartilage were isolated and cell culture was started and terminated at day 10 or day 20. Total RNA from cultivated cells was extracted, and hybridization on Affymetrix microarrays was performed.

We used 10-day-old animals because, at this age, the secondary ossification center has recently begun to form and divides the epiphysis into articular cartilage distally and growth plate cartilage more centrally. The 4 SZ samples were taken from animals 5-8, respectively, whereas the 4 IDZ and 4 RZ samples were each taken from animals 1-2, 3-4, 5-6, and 7-8, respectively.

Project description:To identify genes that maintain the homeostasis of the articular cartilage, we compared gene expression profiles of adult articular cartilage chondrocytes with that of growth plate cartilage chondrocytes in adult (10-week-old) Sprague Dawley (SD) rats. Furthermore, to identify genes that have a potency to regenerate the articular cartilage, we compared gene expression profiles of superficial layer chondrocytes of infant epiphyseal cartilage which form articular cartilage with that of the deep layer chondrocytes which form growth plate cartilage in infant (6-day-old) SD rats.

Project description: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. In addition, comparison of the spatial regulation of articular and growth plate cartilage revealed unexpected similarities between the superficial zone of the articular cartilage and the hypertrophic zone of the growth plate.
