Fig. 2. Principle component analysis of gene expression analysis for microarrays from (a) in vitro (3D-TCS) and (b) in vivo (fetal rat testes).

Fig. 2

Genes on each array were analyzed using principle components analysis in order to group samples by the similarity of genes expression profiles. Developmentally toxic phthalate treatments formed a distinct cluster separate from the controls and developmentally non-toxic phthalate treatments for in vitro (3D-TCS) and in vivo (fetal rat testes) model systems.
