Key difference between reprogrammed adult mouse cells and embryonic stem cells discovered.
Finding may enhance understanding of human embryonic stem cells and lead to better models for regenerative therapies
Adult stem cells may escape the ethical controversies of their embryonic counterparts, but as Christine Soares notes, their practical clinical value is far more murky
Theresa Deisher once shunned religion for science. Now, with renewed faith, she is fighting human-embryonic-stem-cell research in court.
Effects of injunction against Obama administration's stem-cell policy still unclear.
Work shows the value of human embryonic stem cells for disease research.
Work with human embryonic stem cells is 'contrary to ethics'.
Shinya Yamanaka discovered how to revert adult cells to an embryonic state. These induced pluripotent stem cells might soon supplant their embryonic cousins in therapeutic promise
Cells able to generate virtually all other cell types have recently been isolated. One day they could help repair a wide variety of damaged tissues
It was hoped using reprogrammed mature cells would be a noncontroversial alternative to embryo-derived stem cells. But problems like low replication rates and early senescence have impeded their efficacy in generating differentiated cells
A cell printer could make 3-D human tissues for testing new drugs, growing organs or even printing cells directly inside the body
Success may help erase practical hurdles—if not ethical ones—to cloning human embryonic stem cells to study and treat degenerative disorders
A new study offers proof that stem cells can reconnect the inner ear to the brain
Elusive embryonic cells that form blood vessels have now been grown in large numbers
Scientists isolate and culture stem cells from placenta with characteristics of both embryonic and adult stem cells
Reverse-engineered human stem cells may leapfrog the embryonic kind
