Project description:A genomic expression comparison was done among neural progenitor cells cultured on 2D substrates, 3D porous polystyrene scaffolds, and as 3D neural spheres (in vivo surrogate), with the goal of assessing the feasibility of establishing the meaning of 3D and associated physiological relevance at the molecular level Neural progenitor cells were cultured on 2D surfaces, in 3D scaffolds and as 3D neural spheres. Chemical cues are controlled by coating. Only spacial properties of the culture systems were compared.

Project description:A transcriptomic expression comparison was done among superior cervical ganglion (SCG) cells cultured on 2D substrates, 3D porous polystyrene scaffolds, and in freshly dissected tissue (in vivo surrogate), with the goal of assessing the feasibility of establishing the meaning of 3D and associated physiological relevance at the molecular level SCG cells were cultured on 2D surfaces and in 3D scaffolds. Chemical cues are controlled by coating. Only spacial properties of the culture systems were compared. Cells from freshly dissected tissue were used as in vivo surrogates for positive control of 3D cells.

Project description:We hypothesized that generating spinal motor neurons (sMNs) from human induced pluripotent stem cell (hiPSC)-derived neural aggregates (NAs) using a chemically-defined differentiation protocol would be more effective inside of 3D fibrin hydrogels compared to 2D poly-L-ornithine(PLO)/laminin-coated tissue culture plastic surfaces. We performed targeted RNA-Seq using next generation sequencing to determine the substrate-specific differences in gene expression that regulate cell phenotype. Cells cultured on both substrates expressed sMN genes CHAT and MNX1, though persistent WNT signaling contributed to a higher expression of genes associated with interneurons in NAs cultured in 3D fibrin scaffolds. Cells in fibrin also expressed lower levels of astrocyte progenitor genes and higher levels of the neuronal-specific gene TUBB3, suggesting a purer population of neurons compared to 2D cultures. STATEMENT OF SIGNIFICANCE: Fibrin scaffolds can support the neuronal differentiation of pluripotent stem cells. This study provides insight into how fibrin hydrogels affect neuronal induction by analyzing of the signaling pathways activated during the differentiation process. These insights can then be used to tailor the properties of these hydrogels to optimize the generation of sMNs for regenerative medicine applications.

Project description:In order to gain insight into epithelial morphogenesis and the influence of culture geometry on gene expression patterns, Madin Darby Canine Kidney (MDCK) epithelial cells where grown in 2-dimensional (2D) culture or 3-dimensional (3D) culture . MDCK cells cultured in 2D were plated atop a pre-solidified type I collagen gel. Cells cultured under these conditions grew as flat monolayer sheets. In 3D culture, cells are embedded within type I collagen gel. Cells grown under these conditions form large spherical cysts with hollow central lumens. We anticipate, therefore, that these results provide insight into the mechanisms that regulate epithelial cystogenesis. Cells grown in the 2D or 3D geometries were collected from digested type I collagen gels on day 8. The 2D MDCK cells were treated as the control condition and there gene expression patterns were compared to those of 3D grown cells, which served as the experimental condition.

Project description:Microarray analysis was used to evaluate expression differences from a single donor human bone marrow stromal cells (hBMSCs) as a function of varied polymer-based tissue engineering scaffolds. These scaffolds include polycaprolactone (PCL) nanofibers (PCL_NF), films (PCL_SC), poly D,L-lactic acid (PDLLA) nanofibers (PDLLA_NF), films (PDLLA_SC), tissue culture polystyrene (TCPS) and TCPS with osteogenic supplements (TCPS_OS). The results revealed that scaffold structure was able to significantly affect gene expression, with nanofiber scaffolds inducing similar gene expression patterns to hBMCSs cultured with osteogenic media. A library of scaffolds prepared from polycaprolactone or poly D,L-lactic acid was sythesized and cultured with hBMSCs for 14 days with RNA extracted from cells on Day 1 and Day 14. Gene expression analysis was performed using BRB ArrayTools. SC = spun coat, BNF = big nanofiber, TCPS = tissue culture polystyrene, TCPS+OS = tissue culture polystyrene with osteogenic supplements. This data forms is part of a pending publication: Baker et al. Ontology Analysis of Global Gene Expression Differences of Human Bone Marrow Stromal Cells Cultured on 3D Scaffolds or 2D Films and is a subset of the 72 array data referenced in ( Kumar et al. The determination of stem cell fate by 3D scaffold structures through the control of cell shape, Biomaterials (2011) 32, 9188-9196.) The 72 array data set is submitted separately to GEO as GSE50743.

Project description:Microarray analysis was used to evaluate expression differences from a single donor human bone marrow stromal cells (hBMSCs) as a function of varied polymer-based tissue engineering scaffolds. The results revealed that gene expression patterns of hBMSCs grouped according to scaffold. A library of scaffolds prepared from polycaprolactone (PCL) or poly D,L-lactic acid (PDLLA) was sythesized and cultured with hBMSCs for 14 days with RNA extracted from cells on Day 1 and Day 14. Gene expression analysis was performed using BRB ArrayTools. GF = gas foam, SC = spun coat, BNF = big nanofiber, SNF = small nanofiber, FFF = free-form fabricated, TCPS = tissue culture polystyrene, TCPS+OS = tissue culture polystyrene with osteogenic supplements. The 72 arrays data was used previously in the publication: Kumar et al. The determination of stem cell fate by 3D scaffold structures through the control of cell shape, Biomaterials (2011) 32, 9188-9196. A companion data set of 24 arrays was submitted separately to GEO as GSE50744 and will be referenced to Baker et al.
