Comment[ArrayExpressAccession] E-MTAB-1536 MAGE-TAB Version 1.1 Investigation Title Stem cell coculture Comment[Submitted Name] Stem cell coculture Experiment Description This study aims to to compare the gene transcription profiles of endothelial cells and stem cells, when they are cultured alone or when they are cultured together. Thus there are two major questions - how do the cells differ, and how do the cells influence each other's gene expression. Thus there are 4 types of sample: endothelial cell monoculture, endothelial cell coculture, stem cells monoculture, stem cell coculture. There are also 4 biological replicates (independent experiments) leading to 16 array data files.

HUVEC were isolated from umbilical cords as previously described and cultured in M199 supplemented with 20% FCS, 10 ng/ml epidermal growth factor, 35 ?g/ml gentamicin, 1 ?g/ml hydrocortisone (all from Sigma-Aldrich, Poole, UK), and 2.5 ?g/ml amphotericin B (Life Technologies; Carlsbad CA). Human bone marrow derived MSC were purchased from Lonza and cultured in the manufacturer?s recommended medium (MSCGMTM Mesenchymal Stem Cell Growth Medium BulletKit, Lonza Ltd, Basel, Switzerland). They were expanded through 3 passages and used uniformaly at that passage. Coculture of EC with MSC - MSC and EC were co-cultured on opposite sides of filters (6-well format) with 0.4?m pores. EC were seeded on the inner surface first and cultured for 24h to form a confluent layer. Then MSC (5x105cells) were added to the other surface and cocultured with EC for 24h. Cells were retrieved separately from either side of the filter using trypsin for analysis of gene expression . For comparison, MSC or EC were cultured individually on identical filters (monocultures). mRNA was isolated from EC or MSC retrieved from either side of filters, or from monocultures, using the RNeasy Mini Kit (Qiagen, Crawley, U.K.). For microarray analysis, 25ng of each sample of RNA was labelled with Cy3 dye as per protocol in the Low Input Quick Amp Labelling Kit (Agilent Technologies ? 5190-2305). A Specific Activity of greater than 6.0 was confirmed by measurement of 260nm and 550nmwavelengths with a NanoDrop ND-1000 Spectrophotometer. 600ng of labelled RNA was hybridised for 16 hours to Agilent SurePrint G3 Human 8x60K microarray Slides. After hybridisation slides were washed and scanned with a High Resolution C Scanner (Agilent Technologies). Feature extraction was performed using Agilent Feature Extraction Software, with no background substraction.
