2. FIGURE 1
Suppression subtractive hybridization subtraction efficiency. Subtraction efficiency was determined by analyzing the amount of G3PDH present in both the unsubtracted starting cDNA and the subtracted target cDNA through the use of increasing numbers of PCR cycles. MW stands for molecular weight marker. PCR was performed on subtracted (lanes 1–4) and unsubtracted (lanes 5–8) secondary PCR products with G3PDH primers in both forward (lanes 1–8) and reverse subtraction (lanes 9–16). Numbers above each lane indicate PCR cycles.

Northern blot analysis of the genes from the day-1 and day-5 subtracted cDNA library to confirm their differential expression between the two. GDF-8: growth differentiation factor-8; lats2: large tumor suppressor gene-2; Mater: maternal antigen that embryos require; MTi7: MT transposon-like element, clone-7; PTPRD: protein tyrosine phosphatase receptor type D; D1: day 1; D5: day 5.

5. FIGURE 4
Real-time PCR analysis to confirm the differential expression with gene specific primers as listed in Table 1. (A) Amplification profile of septin2 and lats2 between primordial and primary follicles. PMF: primordial follicle; PRIF: primary follicle. (B) Melting curves for septin2 and lats2. (C) Amplification profile of G3PDH between primordial and primary follicles. (D) Melting curves for G3PDH. The mean CT values are as follows: septin2 (primordial: 13.28, primary: 15.42), lats2 (primordial: 19.70, primary: 21.14), and G3PDH (primordial: 12.13, primary: 12.00).

6. FIGURE 5
Differential expression of 11 genes related to cell-cycle regulation between primordial (blue bars) and primary (red bars) follicles. Expression amount was calculated from CT values, and the fold-difference of relative abundance of mRNA was calculated against that of primordial follicles. Experiments were repeated at least three times, and data are expressed as mean ± SEM. *Statistically significant, P<.05.
