SAN FRANCISCO (AP) Research showing that bald mice can grow hair after being implanted with a type of stem cell could lead to a cure for baldness, a group of scientists says.
The project marks the first time that ``blank slate'' stem cells were able to induce hair growth, said Dr. George Cotsarelis, a University of Pennsylvania dermatologist and co-author of the study.
The study was released Sunday on the Web site of the journal Nature Technology in advance of its April publication date.
``We've shown for the first time these cells have the ability to generate hair when taken from one animal and put into another,'' Cotsarelis said in a telephone interview. ``You can envision a process of isolating existing stem cells and re-implanting them in the areas where guys are bald.''
The study confirms what scientists suspected for years: hair follicles contain ``blank slate'' stem cells that give most humans a full head of hair for life.

In laboratories the world over, scientists bent on turning back our biological clocks are looking past harvesting human embryos and cloning in their quest for disease cures.A small but growing group of researchers seeking the proverbial fountain of youth insists its work has no kinship to cryogenics freezing Ted Williams' body or other fantastic scientific forays in life extension.What these scientists hope for is to be able to make old cells young again, imbuing them with all the potential healing power that youthful cells may possess.
Perhaps most significantly, they want to create stem cells without having to destroy embryos in the process.
Years of work remains, but the researchers are hard at work building biological time machines that reverse aging in some cells.
Some are trying to reset biological clocks by mimicking ``magic factors'' in human eggs the only cells in a woman's body not programmed to die.Others are identifying molecules that enable salamanders to re-grow limbs.Chemists in San Diego have created a chemical compound they call ``reversine,'' which resets muscle cells in mice much the same way newts restart limb cell growth after injury.
