Experimental Protocol


A minimum of 1.5E6 HEPs were harvested at day12 of culture and RNA was extracted with Trizol reagent (Sigma) and purified using the RNeasy Mini Kit (Qiagen, Crawley, UK), including an on-column DNaseI digestion, according to the manufacturer’s instructions. RNA yield was determined using the 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA, USA). 8-10 micr-g of total RNA was analysed by microarrays using cells from day 12 of culture. Quality of the total RNA samples and the resulting cRNA was assessed on the Bioanalyzer. Fragmented biotinylated cRNA was prepared and 15μg hybridized to HG-U133 plus 2 GeneChips, according to the manufacturer’s protocols (Affymetrix). The data was normalized by Robust Multi-Array average (RMA) algorithm.
