Identification of a specific ahNSCs gene expression pattern.

(A) Unsupervised hiererarchical clustering analysis based on the global gene expression of five samples of ahNSCs (green) and 31 normal human tissue samples (in triplicate). ahNSCs clustered together with brain-, spinal cord- and tissue foetal brain tissue (B) Unsupervised hierarchical clustering analysis based on gene expression of selected genes (rank product analysis, 1% FDR) in five ahNSCs samples and tissue samples (in triplicate) from brain, foetal brain, and spinal cord. The ahNSCs clustered separately from the tissues. (C) Heat-map illustrating the expression of typical stem cell markers in the ahNSCs, brain tissue and foetal brain tissue.
