a-subunit receptor (AchR) promoter which, when associated with the LacZ
reporter gene and micro- injected into the male pronucleus (1000 to 2000 copies
of inserts), displays no detectable activity (Table 53.2) (Bonnerot et al., 1991).

Elements of Mammalian Fertilization
Further, we did not obtain oocyte activation after microinjection, and thus, we did
not observe formation of a second polar body or female pronucleus. When we
artificially induced oocyte activation with ethanol and then microinjected sperm, ...

Current Topics in Developmental Biology
As calpain II protease degrades the CSF signal and MPF activity disappears,
factor 3 (F3) becomes active and decondenses the maternal and paternal
chromatin in concert to form a female and male pronucleus, respectively. Factor 3
is a ...

Bioregulators of Reproduction
The basis for this difference in time to form a male pronucleus may be dependent
on (1) the size of the sperm nucleus and/or (2) the concentration or activity of the
agents involved in pronuclear development. In sea urchins the difference in size
...

The sperm- specific protamines are replaced by histone and non-histone proteins
during formation of the male pronucleus in preparation for DNA synthesis. In
Ireland, an analysis of penetrated WM bovine oocytes at various intervals after in

The Centrosome in Cell Replication and Early Development
Immediately after entry, the basal body and the axoneme dissociate and the
sperm head undergoes a dramatic metamorphosis to form the male pronucleus (
for review see Fitch et al., 1998). The basal body rapidly associates with the ...

Preimplantation Stages of Pregnancy
So I think the female pronucleus is attracted towards the male pronucleus by the
sperm centrosome during the aster formation (Thibault, C. [I965]. Annls Biol. anim
. Biochim. Biophys., 5, in press). Austin: That is curious, because in Arlmcia the ...

Similarly, DNA synthesis in human sperm injected into hamster oocytes was
delayed until the male pronucleus was fully formed (Terada et al., 2000).
However, in this study, it appeared that DNA synthesis could occur in the female
pronucleus ...

Tetrahymena Thermophila
The migratory (or transfer) pronucleus remains at the junction while the stationary
(or resident) pronucleus becomes located more posteriorly. 8. Migration of
resident pronucleus The resident pronucleus migrates toward the conjugation ...
However, only one sperm pronucleus, nearest to the egg pronucleus fuses with
the latter and forms the zygotic nucleus in the animal hemisphere. The sperm
pronucleus that fuses with female pronucleus is called principal sperm nucleus, ...
