Obama on Stem Cells - Soon to Overturn Bush Policies

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."

Stem Cells in Baby Teeth or Wisdom Teeth to Grow New Teeth

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.

A Moment Of Tooth
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."
