Embryonic Stem Cell Advocates Push Against Evidence and Ethics

treatment for blindness, while Geron Corporation is going to try ES cells on spinal cord injuries.     “The major concern with stem cell therapies is that the transforming cells...

Cells Manage Stress and Death

suicide for the good of the organism.  Two papers in Science describe how cells do it.     DNA damage is like an emergency in the field.  Fortunately, cells have...

Stem Cells of the Adult Kind Steal the Headlines

Stories about stem cell research need to be divided into two sections: those about adult stem cells (AS), which have no ethical ramifications, and stories about embryonic stem cells (ES),...

Cells Can Be Transformed

of producing adult-type l blood cells instead of fetal blood cells, a major advantage compared to the thus far disappointing attempts to produce blood cells from human ESCs [embryonic stem...

Cells Know Their Physics

overlook.  Two recent papers in the Proceedings of the National Academy of Sciences explored physical mechanisms cells use to good advantage.  Good thing cells know their physics, or we could...

Big Gains for Adult Stem Cells Announced

the progress being made with stem cell therapy.  The ability to reprogram adult stem cells to behave just like embryonic stem cells really “electrified the field,” said biologist Rudolf Jaenisch. ...

Ethics Shmethics: Scientists Obsessed with Embryonic Stem Cells

view of the rapidly evolving field of stem cell research” including both adult and embryonic stem cells.  The article noted that “apart from the scientific and technical challenges, there are...

Piston Engine Joins Rotary Engine in Cells

design: There are, of course, big open questions – not least, how the gradients might have been tapped by the earliest cells, which certainly lacked such sophisticated protein machinery as...

Embryonic Stem Cell Researchers Reeling from Judge’s Decision

intercepted with adult stem cells.  “Human umbilical cord blood cells (HUCB) used to treat cultured rat brain cells (astrocytes) deprived of oxygen appear to protect astrocytes from cell death after...

Specialized Molecules Make Cells Work

Reports continue to show that vital cell processes depend on finely-tuned proteins and RNA molecules.  Most of the papers that discuss these specialized molecules fail to mention how they might...

Stem Cell News: Adults Still Lead

Stem cells are still hot.  Most of the significant findings are coming from adult stem cells (AS) or induced pluripotent stem cells (iPS) rather than embryonic stem cells (ES).  For...

Heal the Blind with Stem Cells

in one eye by burns or acid.  Stem cells taken from the limbus, a disk surrounding the iris, and transplanted onto the damaged cornea, were able to regrow corneal cells...

Stem Cells: Hope, Politics, Charity, and Clarity

or whether adult stem cells, such as induced pluripotent stem cells, could work just as well. An article on both embryonic and induced pluripotent stem cells in Science Daily this...

Stem Cells Promise Regeneration

that none of these stories talked about embryonic stem cells.  Most of the stories about embryonic stem [ES] cells this month discussed efforts to understand how they grow and differentiate...

Stem Cell News: Cancer Cures Coming?

creation and destruction of human embryos and/or the harvesting of human egg cells.  To revisit the shameful news about embryonic stem cells over the last decade, type “embryonic stem cells”...
