Project description:In this study, human particulated dentin (HPD) was developed. The characteristic of HPD was examinated by XRD, EDX and cytotoxicity test. HPD was used to implant in the calvarial defects of New Zealand White rabbits. bone tissue and blood samples were taken at 3, 5 and 7 days post-implantation for microarray experiment. The gene expression profiles and signaling pathways were monitored using GeneSpring software and Ingenuity Pathways Analysis (IPA), respectively. We used microarray and IPA to elucidate the global programme of gene expression and identified distinct classes of up- and down- regulated genes during HPD treated healing process.
Project description:Microarray analysis of white adipose tissue (WAT) and bone marrow adipose tissue (BMAT) from 22-week-old or 13-week-old male New Zealand White rabbits. From both cohorts, BMAT was sampled from the distal tibia (dBMAT) and the radius and ulna (ruBMAT), while WAT was sampled from the inguinal (iWAT) and gonadal (gWAT) depots. From the 13-week-old cohort, BMAT was also sampled from the proximal tibia (pBMAT). Sufficient RNA could not be isolated from all tissues for all rabbits, so for some rabbits only a subset of tissues is included.
Project description:In order to identify tissue specific differences in epithelial behavior following injury, we developed a novel animal model of epithelial-restricted injury in the New Zealand White rabbit. A grid of shallow incisional wounds, which extended through the entire epithelium but did not significantly damage the underlying connective tissue, were created on the skin and vaginal mucosa, and samples were taken at various times post-surgery for histology and molecular analysis. All wounds were completely re-epithelialized between 1 and 2 days post-surgery.
