Table 3. The effect of epidermal growth factor (EGF) and leukemia inhibitory factor (LIF) in culture medium on in vitro maturation (IVM) of COCs isolated from deer mice: GVBD, germinal vesicle breakdown.
| Group | Total No. of COC | No. (%b) of oocytes at | |
|---|---|---|---|
| GVBD | MII | ||
| Ca | 39 | 39 | 23 (59c) |
| C+EGF | 36 | 36 | 20 (56c) |
| C+LIF | 36 | 36 | 22 (61c) |
| C+EGF+LIF | 42 | 42 | 35 (83c) |
aC represents control condition, for which COCs were cultured in medium with no EGF or LIF.
bPercentage of COCs in total
cDifferent superscripts indicate the difference is significant (p < 0.05). In other words, the only significant difference is between C+EGF+LIF and the other groups.
