Newts' ability to regenerate tissue replicated in mouse cells
Tissue regeneration a la salamanders and newts seems like it should be the stuff of science fiction. But it happens routinely. Why can't we mammals just re-grow a limb or churn out a few new heart muscle cells as needed? ...

Human embryonic stem cells and reprogrammed cells virtually identical
Human embryonic stem (ES) cells and adult cells reprogrammed to an embryonic stem cell-like state—so-called induced pluripotent stem or iPS cells—exhibit very few differences in their gene expression signatures and are nearly ...

Adult stem cell research far ahead of embryonic
(AP) -- A few months ago, Dr. Thomas Einhorn was treating a patient with a broken ankle that wouldn't heal, even with multiple surgeries. So he sought help from the man's own body.

Scientists 'reprogram' mouse fat cells into clinically useful stem cells
Australian scientists from the Monash Institute of Medical Research have "reprogrammed" adult mouse fat cells and neural cells to become stem cells that can differentiate into a variety of different cells (pluripotency). ...

Stem Cells Immune From Presidential Pressures
(PhysOrg.com) -- A newly published University of Arizona study shows that media coverage of stem cell research remained generally positive despite opposition from the George W. Bush White House. The study shows that news ...

Scientists isolate the first stages of tissue production in human embryonic stem cells
Scientists at the UCLA Broad Stem Cell Research Center have described a population of cells that mark the very first stage of differentiation of human embryonic stem cells as they enter a developmental pathway that leads ...

Stem cells made by reprogramming hold onto their past
Adult cells that have been reprogrammed into induced pluripotent stem cells (iPS cells) do not completely let go of their past, perhaps limiting their ability to function as a less controversial alternative to embryonic stem ...

Reprogrammed cells 'remember,' retain characteristics of their cells of origin
(PhysOrg.com) -- Investigators at the Massachusetts General Hospital (MGH) Center for Regenerative Medicine have confirmed that induced pluripotent stem cells (iPSCs) retain some characteristics of the cells from which they ...

Unearthing King Tet: Key protein influences stem cell fate
Take a skin cell from a patient with Type 1 diabetes. Strip out everything that made it a skin cell, then reprogram it to grow into a colony of pancreatic beta cells. Implant these into your patient and voilà! ...

New discovery brings hope to treatment of incurable blood cancer
Multiple myeloma is one of the most common blood cancers, and at present considered to be incurable. In a new study from Uppsala University, researchers now present a conceptually new model for the development and progression ...

A fateful pause: Genetic mechanism once thought rare may allow rapid cell production
We take our blood for granted, but its creation requires a complicated series of steps, starting with the formation of blood stem cells during early embryonic development, followed by progressive differentiation into the ...

Biologists find a way to lower tumor risk in stem cell therapies
One of the characteristics of embryonic stem cells is their ability to form unusual tumors called teratomas. These tumors, which contain a mixture of cells from a variety of tissues and organs of the body, ...
