2. FIGURE 1
The percentage of cumulus cells (±SEM) positive to Fas, FasL, Bcl-xl, and TIAR in relation to oocyte maturity and when recovered from inseminated fertilized oocytes. Cumulus cells were recovered from 71 MII (white bar), 16 GV and 7 MI (stippled bar), 34 abnormal (shaded bar), and 43 inseminated (solid bar) oocytes. ∗P<.05 indicates significantly different from MII group.

3. FIGURE 2
The percentage (±SEM) of TUNEL-positive cumulus cells in relation to oocyte maturity and when recovered from inseminated fertilized oocytes. Cumulus cells were recovered from 71 MII, 16 GV and 7 MI, 34 abnormal, and 43 inseminated oocytes. ∗P<.05 indicates significantly different from MII group.
