Microarray-based gene expression analysis of hMSC-TERT, hATSCs, hASSCs and hNSSCs. The human bone marrow stromal (mesenchymal) stem cells (hMSC) immortalized with human telomerase reverse transcriptase gene (hMSC-TERT) and stromal cells isolated from adipose tissue (hATSCs), adult dermal skin (hASSCs) and neonatal foreskin (hNSSCs) cells were cultured using plastic adherence. Total RNA was isolated and microarray analysis was carried out. a Venn diagram representing distinct and overlapping gene expression patterns between these cell populations. b Heat-map of a number of CD markers representing a common MSC molecular signature
