University of Pennsylvania researchers, reporting in the April issue of the journal Nature Biotechnology, say they used so-called "blank-slate" stem cells. This type of stem cell differs from embryonic cells - harvested from live human embryos that are destroyed in the process - that have sparked a political debate in the United States.
In this experiment, by contrast, "blank-slate" stem cells were taken from the hair follicles of other adult mice and implanted into the bald mice, the Associated Press reports. The study appears to confirm what scientists had suspected for years - that the "blank-slate" stem cells give most people a full head of hair for life, the wire service says.
About $1 billion (R6,7 billion) a year is spent in the United States combating baldness, the AP reports. But even with their latest research, a cure for people may still be several years away, the scientists caution. – (HealthDayNews)
