Signal gradients in 3-D guide stem cell behavior

Scientists know that physical and biochemical signals can guide cells to make, for example, muscle, blood vessels or bone. But the exact recipes to produce the desired tissues have proved elusive.

Protein lifetime and the stability of cell structures

(Phys.org) —The ability of a cell to move, replicate, and recast itself according to the needs of the organism which it serves, comes at it price. The extreme flexibility of cells takes its origin from the constant turnover ...

Researchers unravel secrets of mussels' clinginess

Unlike barnacles, which cement themselves tightly to the surfaces of rocks, piers or ships, the clamlike bivalves called mussels dangle more loosely from these surfaces, attached by a collection of fine filaments known as ...

Research that holds water

(Phys.org) —It's squishy, synthetic, flexible, mostly water and almost as tough as rubber. No, it's not "flubber"—it's a hydrogel, and now scientists at The University of Akron are exploring new biomedical uses for this ...

How nanotechnology could keep your heart healthy

Since the heart is such a delicate and critical organ, clinicians usually opt not to intervene with the dead cells that remain after a heart attack or cardiac disease. "But we think that all heart attacks deserve some kind ...
