Stem Cell News

Stem cells continue to be hot subjects for research.  They are divided into two basic “political” parties: embryonic stem cells (ES), which raise ethical issues about tampering with human life,...

Inner Ear Hair Cells Overcome Friction

The cochlea, that spiral-shaped structure in the inner ear, is filled with fluid.  In this fluid, tiny hair cells called stereocilia are positioned in bundles along the length of the...

Embryonic Stem Cells Left in iPS Dust

embryonic stem cells as one of the two sources of stem cells, it did not produce any evidence that embryonic stem cells are effective – only the iPS cells. Vision...

Embryonic Stem Cell Decision Overturned

made with adult stem cells.  For instance, induced pluripotent stem cells (iPSC) might be able to treat immune diseases, Medical Xpress reported.  An article on Science Daily detailed the major...

Adult Stem Cell Advances Continue

The momentum for stem cell therapy is still on the side of adult stem cells (ASC), not embryonic stem cell (ESC) research.  Here are some recent findings: Blood vessel repair: ...

Tipping Point for Embryonic Stem Cells?

embryonic stem cells (hESC).  The article says that iPS cells meet the “gold standard” of pluripotency.  In addition, new methods are speeding the tests for pluripotency of iPS cells. Hearty...

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...
