report on in vivo studies of karyomere
nuclear membrane fusion and endoplasmic reticulum shaping that were motivated by earlier in vitro studies of male pronuclear envelope formation that occurs soon after fertilization.
An example is shown in Figure 10 in which karyomere fusion is greatly delayed in eggs injected with 100 [micro]g/m1 DGK.
Karyomeres are individual chromosomes surrounded by nuclear envelopes that form in many but not all early embryos (Wilson, 1898).
