A child born to an HIV-infected mother in Mississippi may be cured after a swiftly administered course of drugs. A number of factors make the child’s case unique, however, and clinicians caution that we have not discovered a general cure for HIV yet. Still, the medical first may hint at ways to fight the AIDS-causing virus .

California's $3 billion stem cell
agency has performed a well-done makeover on its most important
public face – its web site, which is chock-a-block full of useful
information for researchers and the unwashed alike.
“We're up about 25 percent year over
year in unique viewers to the site. A lot of that growth comes from
search, and the rest is from traffic driven through our blog and
Facebook.”
“I've had people inside CIRM (who
have been beta testing this site) tell me that they are finding
content they'd never seen before because the site is so much easier
to navigate.”
“Now people can not only
read about what our grantees are hoping to accomplish, they can read
about what has actually been accomplished with our funding.”
“Most places on the site where you
see tables, you can now download those tables to Excel. You'll notice
the small Excel icon at the lower left of the table. This feature has
long been available for the searchable grants table. Now you'll see
it on all the tables of review reports (see here for
example http://www.cirm.ca.gov/application-reviews/10877)
on the disease fact sheets (see
here http://www.cirm.ca.gov/about-stem-cells/alzheimers-disease-fact-sheet)
and other places throughout the site. This is part of an effort to
make our funding records more publicly available.”
“A unique visitor is Google's
definition (it's one of the metrics they provide). It's a visit from
a unique IP (internet protocol) address. So, if you visit our site
multiple times from one IP address during a day, you count as a
single unique visitor. (Editor's note: It is possible to have
more than one visitor from the same IP address.)
“We get ~23,000-25,000 visits per
month, or ~16,000-18,000 unique visitors. Page views are on the order
of 65,000 a month.”

The $3 billion California stem cell
agency hit it big in San Diego today, finally scoring an editorial
that said “arguably” the agency's largess has made the state “the
world leader in medical research.”
“There
remains a residue of cynicism about CIRM. Critics say the agency
board did the minimum necessary to avoid an intervention by the
Legislature – and also acted to buff the agency’s image should it
seek more bond funding from California voters before its present
funding runs out in 2017, as is now projected.
“These views
may have some merit. But on balance, we think the California
Institute for Regenerative Medicine has – at long last –
responded properly to the fair criticism it faced. Instead of being
exasperated by CIRM, more people should be excited about the great
work it is doing.”

Durham, NC (PRWEB) March 15, 2013
Bone transplantation is a major strategy for the repair of bone defects. However, reconstruction of the mandible (jawbone) has long been a difficult challenge for oral surgeons at least up to now. A new study in the latest issue of STEM CELLS Translational Medicine shows how stem cells can be used to successfully repair the mandible after a molar extraction and, years later, the new bone is still functioning properly.
Interestingly, the regenerated bone is also hard, rather than the spongy kind normally found in the jaw.
The new study is a follow-up to previous investigations by an international team of researchers in which they discovered that mesenchymal stem cells taken from dental pulp and seeded on a collagen scaffold successfully repaired the mandible bone. In this latest work, they checked on patients who had received the mandible bone grafts three years earlier to assess the stability and quality of the regenerated bone and vessel network.
They found the new bone had normal function and was richly vascularized, although was much more compact than the spongy type normally found in the mandible. The team theorized that, most probably, regeneration of compact bone occurs because grafted dental-pulp stem cells do not follow the local signals of the surrounding spongy bone.
The mandible is constructed from spongey bone on account of its role linked to the presence of teeth and their movements, so regeneration of a compact, rather than a spongy bone type, is difficult to justify physiologically. We concluded, therefore, that grafted dental pulp stem cells do not pursue the local environmental signals emanating from the alveolar bone surrounding the graft site, said Gianpaolo Papaccio, M.D., Ph.D., of the Department of Experimental Medicine at Second University of Naples, Naples, Italy. He led the study team that included colleagues from Second University as well as researchers from Universit Politecnica delle Marche, Ancona, Italy; Universit CB, Lyon; European Synchrotron Radiation Facility, Grenoble, France; and the University of Michigan in the United States.
This must be taken into consideration when grafting stem cells, Dr. Papaccio continued. Their behavior may be quite variable and, consequently, their differentiation fate in some cases may be affected more by their specific origin than by the local signals of the treated area.
Although the bone regenerated at the graft sites is not of the proper type found in the mandible, he added, it does seem to have a positive clinical impact. In fact, it creates steadier mandibles, may well increase implant stability and, additionally, may improve resistance to mechanical, physical, chemical and pharmacological agents.
Dental pulp is an interesting source of ready-to-use stem cells to treat bone defects, said Anthony Atala, M.D., Editor of STEM CELLS Translational Medicine and Director of the Wake Forest Institute for Regenerative Medicine. The finding that these cells regenerate compact bone in the mandible indicates a potential role in the treatment of oral cancer.

Washington, Mar 16 (ANI): Transplantation of mesenchymal stem cells cultivated on the surface of nanofibrous meshes could be a novel therapeutic strategy against post-prostatectomy erectile dysfunction (ED), researchers have claimed.
The study was conducted by a group of Korean scientists and will be awarded 3rd prize for best abstract in non-oncology research on the opening day of the congress.
During their investigation, the group aimed to examine the differentiation of human mesenchymal stem cells cultivated on the surface of nanofibrous meshes (nano-hMSCs) into neuron-like cells and repair of erectile dysfunction using their transplantation around the injured cavernous nerve (CN) of rats.
"The objectives of the study reflect a very pertinent need in today's urology practice," the lead author of the investigation Prof. Y.S. Song of Soonchunhyang University School of Medicine in South Korea said.
"Post-prostatectomy erectile dysfunction results from injury to the cavernous nerve that provides the autonomic input to erectile tissue. It is a common complication after radical prostatectomy which decreases the patient's quality of life.
"Although advances in equipment and surgical techniques reduce this complication, patients still experience erectile dysfunction after radical prostatectomy," he said.
Treatment of phosphodiesterase 5 inhibitors shows insufficient effectiveness in the treatment of post-prostatectomy ED and it is believed that the transplantation of stem cells cultivated on the surface of nanofibrous meshes can promote cavernous neuronal regeneration and repair erectile dysfunction.
