Stem Cell Treatment Causes Nasal Growth in Woman’s Back

A nose.

A nose.

I really wanted to come up with a funny title for this one, but everything sounded cheesy. The best I have is: Baby Got (Snot)Back. But then I realized it would only work if she had a nasal growth in her buttocks. Imagine that.

As horrifying as my “creative” titles may be, they aren’t as bad as this story. It serves as a tentative warning to those who bravely volunteer themselves for experimental medical surgeries and tests. Someone’s got to bite the bullet, sure, but I don’t think I could.

via New Scientist:

A woman in the US has developed a tumour-like growth eight years after a stem cell treatment to cure her paralysis failed. There have been a handful of cases of stem cell treatments causing growths but this appears to be the first in which the treatment was given at a Western hospital as part of an approved clinical trial.

‘Berlin Patient’ May Be First Man Cured Of AIDS

aids-cure-firstFrom CBS via Radio Television Caraibes reports:

A 45-year-old man now living in the Bay Area may be the first person ever cured of the deadly disease AIDS, the result of the discovery of an apparent HIV immunity gene.

Timothy Ray Brown tested positive for HIV back in 1995, but has now entered scientific journals as the first man in world history to have that HIV virus completely eliminated from his body in what doctors call a “functional cure.”

Brown was living in Berlin, Germany back in 2007, dealing with HIV and leukemia, when scientists there gave him a bone marrow stem cell transplant that had astounding results.

“I quit taking my HIV medication the day that I got the transplant and haven’t had to take any since,” said Brown, who has been dubbed “The Berlin Patient” by the medical community.

Brown’s amazing progress continues to be monitored by doctors at San Francisco General Hospital and at the University of California at San Francisco medical center.

First Eyeball Grown From Stem Cells

The Guardian reports:

Scientists have used stem cells to grow a rudimentary eye in the laboratory in a landmark study that raises the prospect of creating tissues to treat blindness and tease apart how diseases can destroy eyesight.

The Japanese team is the first to make significant progress in turning embryonic stem cells into an organ as complex as the eye.

Writing in the journal Nature, the scientists describe how they used embryonic stem cells from mice to grow an “optic cup”, a structure that forms the retina and contains the light-sensitive cells and neurons needed to see properly.

The work gives researchers hope for growing parts of the human eye to investigate the progression of devastating diseases that lead to blindness, and to screen for drugs that might slow or even reverse the conditions.

It also raises the more distant prospect of creating banks of healthy retina cells to transplant into patients whose vision has been damaged by illness or accidents.

Bringing Zoo Animals Back To Life

The San Diego zoo and The Scripps Research Institute in La Jolla, California have joined together to conduct research on reproducing rare animals.  The frozen stems cells, in theory, will allow a basis to create sperm and eggs in order to create a reproduction. Paul Aldhous of New Science magazine goes into detail:

“At the annual meeting of the International Society for Stem Cell Research in San Francisco last week, Inbar Friedrich Ben-Nun and Jeanne Loring of Scripps described how they have created induced pluripotent stem (iPS) cells from the frozen skin cells of a deceased male drill (Madrillus Ieucophaeus) an endangered monkey found in Nigeria, Cameroon, and Equatorial Guinea.

The team’s long-term goal is to coax iPS cells into becoming sperm and eggs. They will be making iPS cells from tissue held by San Diego zoo’s Frozen Zoo project – which has samples from some 8400 individuals representing more than 800 species.
