Figure 2. Protein expression relationship between samples of different developmental stages.

(A) The average values of the protein levels of the different age groups were hierarchically clustered. The vertical distance connecting two samples within the dendrogram reflects similarity between the samples. (B) Number of proteins that were significantly different in abundance between P280 and other developmental stages (one-sample student’s t-test, p-≤0.05). P280 was taken as reference for the relative quantification of the other 7 age groups.
