Researchers generate human-monkey chimeric embryos

Investigators in China and the United States have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of time—up to 20 days. The research, despite its ethical concerns, ...

Unraveling a mystery surrounding embryonic cells

Last year, researchers at the University of California, Riverside, identified the early origins of neural crest cells—embryonic cells in vertebrates that travel throughout the body and generate many cell types—in chick ...

Terahertz zaps alter gene activity in stem cells

Terahertz light pulses change gene expression in stem cells, report researchers from Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) and Tokai University in Japan in the journal Optics Letters. ...

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. ...

Taming CRISPR's collateral damage

CRISPR-Cas9 can alter genes at pre-defined sites in specific ways, but it does not always act as planned. An LMU team has now developed a simple method to detect unintended "on-target" events, and shown that they often occur ...
