Table 1 Distribution of pericentromeric signals in fPN and mPN during the 1-cell stage

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

  Female PN (fPN) Male PN (mPN)
  No. of NPBs No. of NPBs not associated with pericentromeric signals No. of NPBs No. of NPBs not associated with pericentromeric signals
PN1/PN2 5.9 ± 2.6 a 1.0 ± 1.7 13.94 ± 4.6 a’ 8.8 ± 8
(n = 16)
PN3 2.8 ± 2.0 b 0.08 ± 0.3 7.8 ± 4. 1 b’c 2.5 ± 2.0
(n = 18)
PN4/PN5 3.9 ± 2.3 b 0.2 ± 0.8 5.7 ± 3 b’c 1.1 ± 1.1
(n = 42)     
  1. Values with superscripts a and a’ are significantly different at p < 0.0001.
  2. Values with superscripts b and b’, and c and c’ are significantly different at p = 0.002.
  3. Values with superscripts a and b are significantly different at p < 0.001.
  4. Values with superscripts c are significantly different at p = 0.05.
