Slicing mitotic spindle with lasers, nanosurgeons unravel old pole-to-pole theory
The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering ...

Oocytes: Going with the flow
Most cells rely on structural tethers to position chromosomes in preparation for cell division. Not so oocytes. Instead, a powerful intracellular stream pushes chromosomes far-off the center in preparation ...

Measuring the strength needed to move chromosomes
(PhysOrg.com) -- It’s about as long as the width of a human hair and only half that length across. So it’s tiny — measured in millionths of a meter — and extremely tricky to manipulate. But the meiotic spindle plays so irresistibly ...

Scientists deconstruct cell division
The last step of the cell cycle is the brief but spectacularly dynamic and complicated mitosis phase, which leads to the duplication of one mother cell into two daughter cells. In mitosis, the chromosomes ...
