Table 3 Organization of pericentric heterochromatin in early and late 2-cell embryos

From: 3D-FISH analysis of embryonic nuclei in mouse highlights several abrupt changes of nuclear organization during preimplantation development

  No. of NPBs No. of NPBs not associated with pericentromeric signals No. of NPBs associated with pericentromeric rims No. of NPBs associated with condensed pericentromeric patches No. of “free” cytoplasmic pericentromeric patches
early 2-cell (n = 20) 13.75 ± 3.78 4.95 ± 1.76 (37%) b 8.10 ± 3.26 (58%) a 0.7 ± 0.57 (5%) a 2.7 ± 1.7 b
late 2-cell (n = 19) 11.78 ± 3.47 3.47 ± 1.54 (29.6%) b’ 2.67 ± 1.64 (24.16%) a’ 4.83 ± 2.4 (37.6%) a’ 4.05 ± 2 b’
  1. Values with superscripts a and a’ are significantly different at p < 0.0001.
  2. Values with superscripts b and b’ differ at p = 0.02.
