Figure 4

The heat map shows the segregation of samples by gene expression. Blastocyst (BL1 to BL5) and milk somatic cell (SC1 and SC2) transcriptomes are distinguished clearly from one another while grouping highly within their own sample types. Average correlation of RPKM for all annotated genes reflected this within BL (r > 0.97) and between sample groups (r < .21) and plotting of log-transformed RPKM values showed a much less linear relationship between milk somatic cells and blastocyst samples.
