Granulosa cells were obtained from 20-26 day-old mice of various genotypes 48h after eCG treatment, using the needle puncture method as previously described. Cells were then infected with adenoviruses to express eGFP or Cre, or overexpress WNT4 in serum-free medium, and subsequently harvested for RNA extraction as described below. Preliminary experiments demonstrated that an infection efficiency of >80% could be obtained at an MOI of ~50 (as determined by analysis of fluorescent signal in Ad-eGFP-infected cells) and that the Ad-Cre and Ad-WNT4 viruses produced efficient recombination of the floxed Ctnnb1 alleles and robust WNT4 overexpression, respectively. Microarray analyses were done using triplicate RNA samples from each adenoviral treatment described above, and using mouse expression set 430 microarrays (Affymetrix, Santa Clara, CA).
