Comparison of ER distribution patterns in cortical section of control or diabetic oocytes at MII stage

Group	No. oocytes examined	Percentage with middle I	Percentage with middle II
Control oocytes	38 (from 3 mice)	31 (81.6%) a	7 (18.4%) a
Diabetic oocytes	32 (from 3 mice)	7 (21.9%) b	25 (78.1%) b

* Experiments were repeated at least two times.

^a,b Values with different superscript letters are significantly different (P <0.05; Fisher exact test).

(middle I): cortical cluster distribution pattern, (middle II): without cortical clusters.
