Single cell mRNA analysis of pancreatic CTCs. a Unsupervised hierarchical cluster analysis and associated heat map of single CTCs (turquoise, yellow), leucocytes (violet), ASPC-1 cells (brown), PANC1 cells (light brown), and SDM103T2 cells (blue). Data are mean-centred and z-score adjusted. Green and red colours in the heat map represent high and low expression levels, respectively, relative to the mean expression of all analysed cells. b Principal component analysis of the single cell data. Each point represents a single cell in the analysis
