New drug delivery method can reverse senescence of stem cells

As we age, our bodies change and degenerate over time in a process called senescence. Stem cells, which have the unique ability to change into other cell types, also experience senescence, which presents an issue when trying ...

Houston team one step closer to growing capillaries

In their work toward 3-D printing transplantable tissues and organs, bioengineers and scientists from Rice University and Baylor College of Medicine have demonstrated a key step on the path to generate implantable tissues ...

The surprisingly simple recipe for starting to grow a limb

How do organisms form limbs in the womb? Scientists have been striving to answer this question not only to deepen our understanding of evolution and embryonic development, but also to help make the dream of regenerating partial ...

Researchers show stem cell fate depends on 'grip'

The field of regenerative medicine holds great promise, propelled by greater understanding of how stem cells differentiate themselves into many of the body's different cell types. But clinical applications in the field have ...

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.
