FIG. 2.

A) Hierarchical clustering analysis of oocytes derived from the ovaries of CF1 mice after follicle culture in vitro (GV oocytes obtained from the alginate culture system) and from oocytes that developed in vivo (GV oocytes from 22-day-old, eCG-primed mice). B) Number of genes showing 5-, 3-, or 2-fold differences in expression between oocytes grown in the alginate culture system and in vivo. C) DAVID annotations to identify enriched biological theme and functional-related gene groups among the genes showing differential expression.
