Oh happy day!
"Bush limited taxpayer money for embryonic stem cell research to a small number of stem cell lines that were created before Aug. 9, 2001. Many of those faced drawbacks. Hundreds more of such lines — groups of cells that can continue to propagate in lab dishes — have been created since then. Scientists say those newer lines are healthier and better suited to creating treatments for diseases, but they were largely off-limits to researchers who took federal dollars.
"We've got eight years of science to make up for," said Dr. Curt Civin, whose research allowed scientists to isolate stem cells and who now serves as the founding director of the University of Maryland Center for Stem Cell Biology and Regenerative Medicine. "Now the silly restrictions are lifted."

Kids losing baby teeth, or having a wisdom tooth extracted? Got liquid nitrogen? Cool article on growing new adult teeth from stem cells in baby teeth.

Advances to Regrow Decaying Choppers Offer More to Chew On Than You'd Think
From the article here: Using stem cells to grow new teeth
"Regenerating a whole tooth is no less complicated than rebuilding a whole heart, says Songtao Shi of the University of Southern California, who heads a team working on creating such a tooth. Not only do you have to create smart tissue (nerves), strong tissue (ligaments) and soft tissue (pulp), you've got to build enamel -- by far the hardest structural element in the body. And you have to have openings for blood vessels and nerves. And you have to make the whole thing stick together. And you have to anchor it in bone. And then you have to make the entire arrangement last a lifetime in the juicy stew of bacteria that is your mouth. It's a nuisance, but researchers are closing in on it. In fact, they think the tooth will probably be the first complex organ to be completely regenerated from stem cells. In part this is because teeth are easily accessible -- say ahhhhh. So are adult stem cells, found abundantly in both wisdom and baby teeth -- no embryos required, and your immune system won't reject your own cells."
By Christine Pollock Breastmilk has been found to contain stem cells, according to research presented in January at the International Conference of the Society for Research on Human Milk and Lactation, in Perth, Australia. Dr. Mark Cregan, lecturer in biochemistry and molecular biology at the University of Western Australia, sees this significant finding as a stepping stone to new, undiscovered benefits of breastmilk. Stem cells are "generic" cells that can make exact copies of themselves and also have the ability to produce specialized cells. While adult stem cells are generally specific to certain cell types such as skin and blood, embryonic stem cells are more versatile because they can produce cells for almost any tissue in the body. However, the use of embryonic cells for research is controversial. Several years ago, while investigating the intricacies of cells in breastmilk, Cregan wondered if it also contained the cells' precursors. He and his team cultured cells from breastmilk and discovered nestin, a stem-cell "marker." In addition to nestin, Cregan and his team found one population of stem cells with the potential to, like embryonic stem cells, differentiate into multiple cell types. "We already know how breastmilk provides for the baby's nutritional needs, but we are only just beginning to understand that it probably performs many other functions," says Cregan. He is eager to see major changes in the next few years as scientists harvest these stem cells, in a completely ethical manner, to research treatment for conditions such as autoimmune diseases, cancer, spinal injuries, diabetes, and Parkinson's disease. ~~~

WASHINGTON, DC -- March 24, 2008 -- All of the patients with Parkinson's disease who were treated by implantation of stem cells into the brain have achieved substantial improvement in terms of beneficial changes that were apparent within 1 week of the implant procedure.
"Our 1 patient who has reached 1 year following the implant has achieved an 80% improvement in his Parkinson's disease-related symptoms," said Augusto Brazzini Armestar, MD, Director, Instituto Brazzini Radiologos Asociados, Lima, Peru.
In his featured poster presentation on March 18 here at the Society of Interventional Radiology (SIR) 33rd Annual Scientific Meeting, Dr. Armestar said the implants of purified autologous bone-marrow-derived stem cells were attempted in hopes that the cells would implant in areas of the brain depleted of neurotransmitters.
"Stem cells from bone marrow have the ability to differentiate into neurons and other tissues," he said. "Usually stem cells migrate to sites of injury. However, they do so in very small quantities, and so full regeneration is not gained."
Dr. Armestar and his colleagues attempted to get more of the stem cells into the brain by using interventional radiological techniques. Stem cells were first harvested from patients' bones and were sent to the pathology laboratory to be separated and purified, at which time they were returned to the operating theatre.

Stem Cell Treatment May "Cure" Diabetes:
"'The beauty of the treatment protocol used here is that the patient's own bone marrow stem cells were used, guaranteeing a perfect match,' Weldon said. 'Should these patients remain insulin-free, the treatment is likely to be particularly useful for those suffering from Juvenile Diabetes who have difficultly in maintaining proper insulin levels, as well as for those who have difficulty accessing appropriate health care,' he said."
~~~
I'm wondering how someone who has "difficulty accessing appropriate health care" will benefit from this treatment? Isn't this considered appropriate health care? Or if Weldon means those who can't afford a doctor's visit & insulin? If so how would they afford this?
Anyway, the fact that using one's own stem cells makes such a profouund difference is good news.
