Experiments explain why almost all multicellular organisms begin life as a single cell
Any multicellular animal, from a blue whale to a human being, poses a special difficulty for the theory of evolution. Most of the cells in its body will die without reproducing, and only a privileged few will ...

Math predicts size of clot-forming cells
UC Davis mathematicians have helped biologists figure out why platelets, the cells that form blood clots, are the size and shape that they are. Because platelets are important both for healing wounds and in strokes and other ...

Mechanical properties of stem cells can foretell what they will become
To become better healers, tissue engineering need a timely and reliable way to obtain enough raw materials: cells that either already are or can become the tissue they need to build. In a new study, Brown ...

Shaping up: Controlling a stem cell's form can determine its fate
"Form follows function!" was the credo of early 20th century architects making design choices based on the intended use of the structure. Cell biologists may be turning that on its head. New research by a ...

Exercise boosts health by influencing stem cells to become bone, not fat, researchers find
McMaster researchers have found one more reason to exercise: working out triggers influential stem cells to become bone instead of fat, improving overall health by boosting the body's capacity to make blood.
