Science Signaling, 2002
During meiosis, the replicated chromatids remain condensed, which is important to prevent inappropriate DNA replication and to allow proper progression through the second meiotic cell cycle. Di Agostino et al. examined meiosis stimulated by the phosphatase inhibitor okadaic acid in mouse spermatocytes.

Regulation of chromosome condensation and segregation
Current Opinion in Genetics & Development, 2003Regulated and controlled chromosome condensation and segregation is essential for the transmission of genetic information from one generation to the next. A myriad of techniques has been utilized over the last few decades to identify proteins required for the organized compaction of the massive length of a cell's DNA.

A Condensed View of the Chromosome Passenger Complex
Trends in Cell Biology, 2020The inner centromere is a region on the mitotic chromosome that serves as a platform for mitotic signaling and possesses unique biophysical properties that enable it to withstand relatively large pulling forces that are generated by kinetochores (KTs) during chromosome segregation.

Mitotic chromosome condensation in vertebrates
Experimental Cell Research, 2012Work from several laboratories over the past 10-15 years has revealed that, within the interphase nucleus, chromosomes are organized into spatially distinct territories [T. Cremer, C. Cremer, Chromosome territories, nuclear architecture and gene regulation in mammalian cells, Nat. Rev. Genet. 2 (2001) 292-301 and T. Cremer, M. Cremer, S.

Chromosome Cohesion, Condensation, and Separation
Annual Review of Biochemistry, 2000▪ Abstract  The faithful segregation of genetic information requires highly orchestrated changes of chromosome structure during the mitotic cell cycle. The linkage between duplicated sister DNAs is established during S phase and maintained throughout G2 phase (cohesion).

Premature chromosome condensation in irradiated man
Human Genetics, 1976Micronuclei and premature chromosome condensation previously described in mammalian cells exposed to different types of irradiation and chemicals in vitro or in vivo could be demonstrated in cultured lymphocytes derived from chronically low-dose irradiated persons.

Mitotic chromosome structure and condensation
Current Opinion in Cell Biology, 2006Mitotic chromosome structure has been the cell biology equivalent of a 'riddle, wrapped in a mystery, inside an enigma'. Observations that genetic knockout or knockdown of condensin subunits or topoisomerase II cause only minimal perturbation in overall chromosome condensation, together with analysis of early stages of chromosome condensation and ...

Preleptotene chromosome condensation in mouse oogenesis
Cytogenetics and Cell Genetics, 2008In the embryonic mouse ovary, studies of meiotic onset reveal the existence of a preleptotene stage of chromosome condensation. This stage begins with the appearance of very fine and irregular filaments, which gather around the chromocenters constituted by centromeric heterochromatin.

Premature chromosome condensation induced by electrofusion
Cytogenetics and Cell Genetics, 2008Premature chromosome condensation of G<sub>1</sub> G<sub>2</sub>, and S-phase chromosomes has been achieved by the use of electrofusion in the fusion of Chinese hamster ovary (CHO) cells and HeLa cells and CHO cells with human leukocytes.

[Studies on prematurely condensed chromosomes and induced condensed chromosomes with SEM].
Yi chuan xue bao = Acta genetica Sinica, 1997The ultrastructure of prematurely condensed chromosomes (PCC) in BK cells and the CHO metaphase chromosomes (the PCC inducer) were studied with cell fusion technique and SEM. The methods for preparing complete specimens for SEM, were used to eliminate artifact as complete as possible, so the natural states of PCC ultrastructure, especially the ...
