Nanoparticles can turn off genes in bone marrow cells

Using specialized nanoparticles, MIT engineers have developed a way to turn off specific genes in cells of the bone marrow, which play an important role in producing blood cells. These particles could be tailored to help ...

Super-potent blood stem cells discovered in human embryos

Stem cells that form the blood and immune system, so-called hematopoietic stem cells (HSCs), have important applications in the treatment of blood cancers and other diseases of the immune system. Through blood stem cell transplantation, ...

Turning off 'junk DNA' may free stem cells to become neurons

For every cell in the body there comes a time when it must decide what it wants to do for the rest of its life. In an article published in the journal PNAS, NIH researchers report for the first time that ancient viral genes ...

Scientists find optimal age of stem cells

Biophysicists from the Moscow Institute of Physics and Technology and Vladimirsky Moscow Regional Clinical Research Institute have determined the optimal age of reprogrammed stem cells suitable for restoring heart tissue. ...

Nanostimulators boost stem cells for muscle repair

In regenerative medicine, an ideal treatment for patients whose muscles are damaged from lack of oxygen would be to invigorate them with an injection of their own stem cells.

First supercentenarian-derived stem cells created

People who live more than 110 years, called supercentenarians, are remarkable not only because of their age, but also because of their incredible health. This elite group appears resistant to diseases such as Alzheimer's, ...

Silkworms provide new spin on sticky molecules

Silkworms are useful for more than just making strong and absorbent strings of silky thread for the textiles industry. A group of KAUST scientists has now coaxed these grub-like insects into making the human form of E-selectin, ...
