Easy access to insta-tans, doctors say, may be contributing to a frightening spike in skin-cancer rates among the young. The incidence of melanoma, the most lethal form of skin cancer, has doubled in the U.S. since 1975 among women ages 15 to 29. This year 2,050 of them are expected to be diagnosed with the malignancy. "Skin cancer used to be something old people got," says Dr. James Spencer, a clinical professor of dermatology at New York City's Mount Sinai School of Medicine. "Not a month goes by that I don't see somebody in their...

Lanza's group is also close to filing for FDA permission to begin clinical trials on three cell-based therapies: one for macular degeneration, one for repairing heart muscle and another for regenerating damaged skin. Not to to be outdone, the academic groups are just a few steps behind.

They can be coaxed to produce more cells of a specific lineage and do not have to be extracted from embryos Drawbacks They can generate only a limited number of cell types, and they are difficult to grow in culture...
NUCLEAR-TRANSFER EMBRYOS Why they are useful These embryos are created using the technique that created Dolly, the cloned sheep. Stem cells can be custom-made by inserting a patient's skin cell into a hollowed human egg. Any resulting therapies would not run the risk of immune rejection...
