DFG remains skeptical of the cloning of human cells
According to a paper published in the journal Stem Cells, an American group has succeeded in inserting cell nuclei from human skin cells into human enucleated oocytes and to stimulate these new cells to undergo cell division in the laboratory. view more (2008-01-23)
Alzheimer's disease as a case of brake failure?
Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease (AD). When the brakes fail, dementia results. view more (2008-06-25)
Researchers discover pathway to cell size, division
Organisms precisely regulate cell size to ensure that daughter cells have sufficient cellular material to thrive or to create specific cell types: a tiny sperm versus a gargantuan egg for example. view more (2007-07-31)
European researchers tackle mitosis
Scientists at the European Molecular Biology Laboratory (EMBL) join forces with top scientists from eleven research institutes in Austria, Germany, Italy, France and the United Kingdom for "MitoCheck" - the largest integrated research project on cell cycle control within the European Commission's 6th Framework Programme (FP6). The... view more... (2004-07-15)
MBL Scientists Find Evidence of RNA in Organelle Essential to Cell Division
Despite more than a century of study, scientists know relatively little about the inner workings of centrosomes—organelles essential to cell division in humans and animals. view more (2006-06-07)
Dartmouth researchers find new protein function
A group of Dartmouth researchers has found a new function for one of the proteins involved with chromosome segregation during cell division. view more (2009-01-09)
Let's Stick Together - A Protein Protects Chromosome Bonds
The protein Mnd2 inhibits premature separation of chromosomes during the formation of gametes. The now published discovery of this regulatory function may help to understand the origin of some common congenital chromosome defects. The project of a team of the University of Vienna funded by the Austrian Science Fund (FWF) contributes to the Campus... view more... (2005-03-29)
Brain size may depend upon how neural cells are cleaved
Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development. view more (2005-07-15)
Research shines spotlight on a key player in the dance of chromosomes
Cell division is essential to life, but the mechanism by which emerging daughter cells organize and divvy up their genetic endowments is little understood. In a new study, researchers at the University of Illinois and Columbia University report on how a key motor protein orchestrates chromosome movements at a critical stage of cell division. view more (2008-05-14)
Trainor Lab characterizes gene essential for prenatal development of nervous system
The Stowers Institute's Trainor Lab has demonstrated the role of a gene important to the embryonic development of the nervous system, a process that requires coordination of differentiation of immature neural cells with the cycle of cell division that increases their numbers. Until now, the mechanisms regulating these distinct cellular activities... view more... (2008-02-04)
Newly Discovered Mechanism in Cell Division has Implications for Understanding Aberrant Chromosome's Role in Cancer, According to Penn Study
"A biologist, a physicist, and a nanotechnologist walk into a ..." sounds like the start of a joke. Instead, it was the start of a collaboration that has helped to decipher a critical, but so far largely unstudied, phase of how cells divide. view more (2009-08-18)
How red blood cells nuke their nuclei
Unlike the rest of the cells in your body, your red blood cells lack nuclei. That quirk dates back to the time when mammals began to evolve. Other vertebrates such as fish, reptiles, and birds, have red cells that contain nuclei that are inactive. Losing the nucleus enables the red blood cell to contain more oxygen-carrying hemoglobin, thus... view more... (2008-02-11)
Study reveals a reprogrammed role for the androgen receptor
The androgen receptor - a protein ignition switch for prostate cancer cell growth and division - is a master of adaptability. view more (2009-07-28)
Researchers identify potential new avenue to attack cancer
New insight into how human cells reproduce, published by cancer researchers at Michigan State University and the Van Andel Research Institute in Grand Rapids, could help scientists move closer to finding an "off switch" for cancer. view more (2009-08-13)
Brown Cancer Biologists Identify Major Player in Cell Growth
When cells go about the business of dividing, they can get sidelined. Maybe there aren't enough nutrients. Maybe there aren't the right signals to resume multiplying. Either way, cells go quiet. view more (2007-02-07)
Disorderly protein brings order to cell division
The secret to the ability of a molecule critical for cell division to throw off the protein yoke that restrains its activity is the yoke itself—a disorderly molecule that seems to have a mind of its own. view more (2007-01-29)
Pol3 mutation disrupts organ growth
The cellular mechanism that turns DNA into all of the thousands of proteins that make up a human body is itself both intricate and interesting. view more (2007-11-27)
IAH appoints new Head of Epidemiology
The Institute for Animal Health is pleased to announce that Dr Matthew Baylis has been appointed as Head of the Division of Epidemiology. Dr Baylis will take charge of a re-structured division responsible for experimental epidemiology and mathematical modelling of a number of infectious diseases across the Institute's three laboratories at... view more...

Biologists use computers to study bacterial cell division
A group of computational biologists at Virginia Tech have created a mathematical model of the process that regulates cell division in a common bacterium, confirming hypotheses, providing new insights, identifying gaps in what is understood so far, and demonstrating the role of computation in biology. view more (2008-01-25)
Scientists take a step nearer to creating an artificial egg using a somatic cell
Scientists believe that they are an important step nearer to success in creating an artificial egg from the combination of the nucleus of a somatic cell and an oocyte which has had its DNA-carrying nucleus removed, a conference of international fertility experts heard today (Tuesday 1 July). Dr Peter Nagy, from Reproductive Biology Associates,... view more... (2003-06-28)
