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

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

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
  1. * Experiments were repeated at least two times.
  2. a,b Values with different superscript letters are significantly different (P <0.05; Fisher exact test).
  3. (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.
