Project description:We have compared the gene expression profile of rat Achilles tendon-derived stem cells in post-natal tendon development. Rat tendon stem/progenitor cells (TSPCs) were isolated at different stages of post-natal development: TSPCs-1d, TSPCs-7d and TSPCs-56d.

Rat tendon stem/progenitor cells (TSPCs) were isolated at different stages of post-natal development: TSPCs-1d, TSPCs-7d and TSPCs-56d. TSPCs at different post-natal development stages (1d, 7d and 56d) were isolated, cultured and used for microarray analyses at passage 2. All TSPCs in this study were of isolated from more than one individual. Total RNA was extracted and fragmented biotin-tagged cRNA was hybridized to Rat Genome 230 2.0 Array.
Project description:Although the biological events that modulate tendon embryonic development are widely studied, how they orchestrate postnatal tendon maturation that is similar to tendon regeneration is still largely unknown For molecular profiling of tendon maturation, we performed mRNA microarray analyses of total rat tendon tissue harvested from normal neonatal and 6-8w Achilles’ tendons and identified meaningful genes in down-regulated group
Project description:In order to establish a rat embryonic stem cell transcriptome, mRNA from rESC cell line DAc8, the first male germline competent rat ESC line to be described and the first to be used to generate a knockout rat model was characterized using RNA sequencing (RNA-seq) analysis.
Project description:Amniotic derived cells are ideal seed cells for regenerative medicine protocols since they conjugate a remarkable plasticity to safety properties. This study investigated the role exerted by human amniotic cells during the process of tendon healing. In particular, in the present research it has been evaluated, by microarray technique, the presence of transcriptome variations in human amniotic epithelial (hAECs) and mesenchymal (hAMCs) stem cells when xenotransplanted into the preclinical ovine model of tendon defect, compared to freshly isolated ones. This analysis allowed to understand in which way, after 28 days transplantation, hAECs and hAMCs transcripts have been affected. Total of 4 experiments.Two-condition experiment, Human amniotic stem cells xenotransplantated in a sheep achilles tendon vs.HAEC/HAMC Biological replicates: 2 Xenotrasplatations. One replicate per array.
