Project description:To investigate the differences in cell behavior and biological functions of Schwann cells on submicron grooved films and flat films, gene expression profiles of Schwann cells were analyzed. We then performed gene expression profiling analysis using data obtained from RNA-seq of Schwann cells at 5 days.

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.

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:Leptomeningeal metastasis (LM), or spread of cancer cells into the cerebrospinal fluid, is characterized by a rapid onset of debilitating neurological symptoms and markedly bleak prognosis. The lack of reproducible in vitro and in vivo models has prevented development of novel, LM-specific therapies. Although LM allows for longitudinal sampling of floating cancer cells with a spinal tap, attempts to culture patient-derived leptomeningeal cancer cells have not been successful. We therefore employ leptomeningeal derivatives of human breast and lung cancer cell lines that reproduce both floating and adherent phenotypes of human LM in vivo and in vitro. We introduce a trypsin/EDTA-based fractionation method to reliably separate the two cell subsets and demonstrate that in vitro cultured floating cells have decreased proliferation rate, lower ATP content, and are enriched in distinct metabolic signatures. Long-term fractionation and transcriptomic analysis suggest a high degree plasticity between the two phenotypes in vitro. Floating cells colonize mouse leptomeninges more rapidly and associate with shortened survival. In addition, patients harboring LM diagnosed with CSF disease alone succumbed to the disease earlier than patients with adherent (MRI-positive) disease. Together, these data support mechanistic evidence of a metabolic adaptation that allows cancer cells to thrive in their natural environment but leads to death in vitro.
