Maternal diabetes causes abnormal dynamic changes of endoplasmic reticulum during mouse oocyte maturation and early embryo development

Table 2 Comparison of ER distribution patterns in control or diabetic oocytes at Pro-MII stage

Group	No. oocytes examined	Percentage with I	Percentage with II	Percentage with III
Control oocytes	35 (from 3 mice)	27 (77.1%) ^a	5 (14.3%) ^a	4 (11.4%) ^a
Diabetic oocytes	30 (from 3 mice)	5 (16.7%) ^b	18 (60.0%) ^b	7 (23.3%) ^b

* Experiments were repeated at least three times.
^a,b Values with different superscript letters are significantly different (P <0.05; Fisher exact test).
(I): perinuclear distribution pattern, (II): homogeneous distribution, (III): clustering distribution.
