Transferrin and antioxidants partly prevented mouse oocyte oxidative damage induced by exposure of cumulus-oocyte complexes to endometrioma fluid

Table 4 Effects of endometrioma fluid, transferrin, cysteamine and cystine on mouse cumulus cells (CCs) viability

Groups	ADP/ATP	CCs viability (%)
1:Control	0.34 ± 0.14 ^a	82.7 ± 3.8 ^a
2: Exposure to endometrioma fluid	0.72 ± 0.39 ^c	51.8 ± 9.4 ^c
3: Exposure to endometrioma fluid +Transferrin	0.49 ± 0.18 ^b	80.3 ± 7.7 ^a
4: Exposure to endometrioma fluid + Cysteamine and Cystine	0.46 ± 0.25 ^b	70.4 ± 8.2 ^b

Within each column, data with different superscripts are different at p < 0.05. Each treatment was repeated three times with 5 samples for each time. To determine ATP/ADP content within cumulus cells, cumulus cells denuded from 50 COCs from each treatment group were collected for each sample preparation
