] The tooth fairy could soon face competition for baby
] teeth from scientists who have discovered the teeth are a
] source of stem cells. The cells could help repair damaged
] teeth and perhaps even treat neural injuries or
] degenerative diseases.
]
] Currently, researchers can isolate two types of stem
] cells. Embryonic stem cells can develop into any cell in
] the body, but their harvesting requires the destruction
] of embryos, which pro-life groups oppose. Adult stem
] cells avoid this problem, but have more limited
] abilities. Now it appears that the stem cells from
] children's lost teeth could provide an intermediate and
] easily accessible source.

So...this is cool....but at the same time, it makes me conjure up images of researchers sneaking around dentists offices. Kinda funny.
