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

Table 3 Comparison of ER distribution patterns in equatorial section of control or diabetic oocytes at MII stage

Group	No. oocytes examined	Percentage with left I	Percentage with left II	Percentage with left III
Control oocytes	38 (from 3 mice)	30 (78.9%) ^a	5 (13.2%) ^a	3 (7.9%) ^a
Diabetic oocytes	32 (from 3 mice)	6 (18.8%) ^b	12 (37.5%) ^b	14 (43.8%) ^b

* Experiments were repeated at least two times.
^a,b Values with different superscript letters are significantly different (P <0.05; Fisher exact test).
(left I): no labeling in the area assumed to be the meiotic spindle poles, (left II): perinuclear distribution pattern, (left III): small areas of ER fluorescence within the deeper cytoplasm.
