Identification of expressed genes in regenerating rat liver in 0-4-8-12 h short interval successive partial hepatectomy

Figure 3 Cluster analysis of 185 elements. A: The difference of their intensity was identified more than 2-fold at least at one time point; B: A hierarchical clustering of five time points indicated that the genes in these time points hardly had a common expression profile; C: The k-means method was used and these genes were classified into seven clusters; D: Five distinct temporal patterns were designated. a. Immediate induction; b. Late induction; c. Consistent induction; d. Late suppression; e. Consistent suppression.
