From: Genome-wide gene expression profiling of testicular carcinoma in situ progression into overt tumours
Hierarchical and K-means clustering of genes expressed specifically in testicular SEM or N-SEM. Results from the microarray analysis were filtered to show genes whose expression would discriminate between the two overt tumour types. This list was then subjected to hierarchical and K-means clustering (K was set to 4 according to the number of groups filtered for) using Euclidian distance measures. The clustering was carried out using the Genesis software (Sturn et al, 2002). Results on the CIS samples are from Almstrup et al (2004).
