Endothelial colony forming cells (ECFCs) were isolated from term umbilical cord blood units. ECFCs were expanded under standard, fetal bovine serum (FBS) containing endothelial medium, or transferred to chemically defined endothelial media without FBS. Microarray expression profiling was applied to compare the transcriptome profiles in FBS-containing versus FBS-free culture.2010/06/29GSE20504GSM515231GSM515222GSM515223GSM515224GSM515225GSM515226GSM515227GSM515228GSM515229GSM51523057020504Homo sapiens[20497237]
