It was previously shown that fully grown ovarian germinal vesicle (GV) oocytes of adult mice exhibit several nuclear configurations that differ essentially by the presence or absence of a ring of condensed chromatin around the nucleolus. These config

SummaryNuclei of embryonic red blood cells (e-RBC) from 12-day mouse fetuses are arrested in Gophase of the cell cycle and have low transcriptional activity. These nuclei were transferred with help of polyethylene glycol (PEG)-mediated fusion to part

The present study examined nuclear remodeling in rabbit nuclear transfer (NT) embryos formed from metaphase II (MII) oocytes aged in vivo until 19 hr postcoitum (hpc), enucleated, and fused at 22-26 hpc with 32-cell morula blastomeres by means of ele

SummaryAn electron microscopic study of the rabbit zygote has shown the presence of numerous paracrystalline structures (PSs) around the pronuclei. The majority of these structures are situated in the narrow space between pronuclei. The PSs during in

We have analyzed the transcriptional activity of somatic cell nuclei fused with artificially activated mouse oocytes. Two types of somatic cells have been used: transcriptionally silent thymocytes, obtained from the thymus of newborn mice, and transc

We have analyzed the distribution of nuclear and nucleolar proteins during the period of oocyte's growth. Oocytes were isolated mechanically or enzymatically from ovaries of juvenile mice of various ages (from 1 to 28 days after birth). Small nuclear

Nucleate and anucleate fragments of parthenogenetically activated mouse oocytes, as well as cybrids obtained by fusion of anucleate fragments (cytoplasts) of maturing and activated matured oocytes were fertilized at different time after activation. R

Using video-enhanced fluorescence microscopy, we describe in live mouse zygotes the paternal chromatin changes undergone after fertilization. We focus on the sperm recondensation process and the formation of the paternal pronucleus, in relationship w

The ultrastructure of oocyte and sperm nuclei was studied in mouse ovarian oocytes inseminated in vitro and cultured for 1 1/2 and 3 h in a medium containing dbcAMP or lacking the maturation inhibitor. In oocytes blocked at the germinal vesicle (GV)
