How cells grow and divide is a question that was raised more than 100 years ago. Despite years of research and in-depth knowledge of several molecular mechanisms, the complete system that regulates and coordinates both of those activities within Schizosacc ...
Since stem cells have the unique ability to produce more of themselves (i.e. to "self-renew") and to generate specialized tissue cells, they are an ideal source of cells for regenerative medicine and in vitro tissue models. In order to fully exploit this p ...
Imprinted genes and neural stem cells (NSC) play an important role in the developing and mature brain. A central theme of imprinted gene function in NSCs is cell survival and G1 arrest to control cell division, cell-cycle exit, migration and differentiatio ...
Asymmetric cell division is essential for normal human brain development. Mutations in several genes encoding centrosomal proteins that participate in accurate cell division have been reported to cause autosomal recessive primary microcephaly (MCPH). By ho ...
During the bacterial cell cycle, chromosome replication and cell division must be coordinated with overall cell growth in order to maintain the correct ploidy and cell size. The spatial and temporal coordination of these processes in mycobacteria is not un ...
The cell cycle orchestrates timely duplication and distribution of cellular components to daughter cells. Checkpoints operate to survey the faithful completion of specific steps during the cell cycle, thus ensuring the equal segregation of genetic material ...
The mechanism of chromatin compaction in mitosis has been well studied, while little is known about what controls chromatin decompaction in early G1 phase. We have localized the Condensin subunit Brn1 to a compact spiral of rDNA in mitotic budding yeast ce ...
Centrioles are microtubule-based organelles found in most eukaryotic cells and that are critical for the formation of cilia and flagella, as well as of centrosomes in animal cells. The number of centrioles must be strictly regulated in proliferating cells ...
Asymmetric cell division is critical for generating daughter cells that possess distinct fates during development and in stem cell lineages. Correct orientation of the mitotic spindle with respect to the polarity axis is crucial to this process. In the one ...
Brucella pathogens are responsible for brucellosis, a worldwide zoonosis. They are facultative intracellular pathogens characterized by their asymmetric division and their unipolar growth. This growth modality generates poles with specialized functions (th ...
