Stem cell op may 'restore sperm'

Sperm

Boys left infertile by childhood cancer treatment may one day be able to produce healthy sperm by using stored stem cells, monkey research suggests.

 

Why brain tumors are so hard to destroy

Brain Tumor

The most common and aggressive brain tumor grows by turning normal brain cells into stem cells, which can continuously replicate and regrow a tumor with only a handful of cells left behind, new research finds.

 

Stem Cells from Blood May Banish Wrinkles, Restore Elasticity to Aging Faces

Wrinkles

For some, wrinkles are seen as a sign of character. For most, they are an unwelcome reminder of ageing. However, scientists are developing a method that may finally end the need for the routine of treatments and moisturisers used to try to keep facial lines at bay.

 

Girl's stem cells used to make her a new vein

For the first time doctors have successfully transplanted a vein grown with a patient's own stem cells, another example of scientists producing human body parts in the lab. In this case, the patient was a 10-year-old girl in Sweden who was suffering from a severe vein blockage to her liver. Last March, the girl's doctors decided to make her a new blood vessel to bypass the blocked vein instead of using one of her own or considering a liver transplant.

 

Report: Women have rare egg-producing stem cells

Ovaries

For 60 years, doctors have believed women were born with all the eggs they'll ever have. Now, Harvard scientists are challenging that dogma.

 

Study: Stem cells may aid vision in blind people

Two legally blind women appeared to gain some vision after receiving an experimental treatment using embryonic stem cells, scientists reported Monday....

 

Real 'Benjamin Button'? Stem cells reverse aging

Benjamin Button

Scientists may one day slow down aging with a simple injection of youthful stem cells. They’ve just proven this can be done in mice, according to a study published Tuesday in Nature Communications. The mice, which had been engineered to mimic a human disease called progeria, would normally have grown old when they were quite young. But that changed when researchers injected muscle stem cells from healthy young mice into the bellies of the quickly aging mice. Within days, the doddering and frail mice began to act like they were living the storyline of “The Strange Case of Benjamin Button” as they started looking and acting younger.

Senh: That's getting scary. By the time this becomes useful, we'll hopefully have colonized the moon and Mars for the increasing population.

 

Sperm from mice stem cells offers infertility hope

Sperm from mice stem cells offers infertility hope

A team of scientists has reported producing viable sperm using the stem cells of mice in an experiment that researchers hope could one day lead to treating infertile men....

 

Stem cell lawsuit tossed

A federal judge has ruled against a lawsuit that temporarily halted the expansion of federally-funded human embryonic stem cell research.

 

'Better way' to grow stem cells

A new plastic surface which overcomes the difficulties associated with growing adult stem cells has been developed, scientists claim.
