Project description:A series of chips with some repeated measurments. Each chip represents a pool of 4 collagen/chondroitin sulfate tissue engineering scaffold meshes seeded with 1 x 10^6 IMR-90 Human Fibroblasts. mRNA was isolated at 30 minutes, 1, 2, 4, 8, 12, 24, 48, and 72 hours after seeding. Keywords = tissue engineering mesh, collagen, chondroitin sulfate, biomaterials design Keywords: time-course
Project description:A goal of tissue engineering is to produce a scaffold material that will guide cells to differentiate and regenerate functional replacement tissue at the site of injury. Little is known about how cells respond on a molecular level to tissue engineering scaffold materials. In this work we used oligonucleotide microarrays to interrogate gene expression profiles associated with cell-biomaterial interactions. We seeded collagen-glycosaminoglycan meshes, a widely used tissue engineering scaffold material, with human IMR-90 fibroblasts and compared transcript levels with control cells grown on tissue culture polystyrene. Genes involved in cell signaling, extracellular matrix remodeling, inflammation, angiogenesis and hypoxia were all activated in cells on the collagen-GAG mesh. Understanding the impact of a scaffold on attached cells will facilitate the design of improved tissue engineering materials.
Project description:IMR-90 Human Fibroblasts were seeded onto TCPS dishes. mRNA was isolated at 1, 2, 4, 8, 12, 24, 48 and 96 hours. This time course was used as a control for gene expression studies on collagen/chondroitin sulfate tissue engineering scaffold materials using the same cell line. Keywords = tissue culture plates Keywords: time-course
