Scientists gave mice a high fat diet, after which, the mice showed growth of new brain cells and less weight gain.
"We really don't understand the function of these neurons in the normal brain," study researcher Seth Blackshaw, an associate professor at Johns Hopkins University School of Medicine, told LiveScience.
An international team said July 22 it had cloned not one mouse, but dozens, from adult mice. Ryuzo Yanagimachi of the the University of Hawaii, said they had cloned several generations of mice and hoped their method would prove to be a breakthrough for both animal breeding and basic scientific research. Three generations of cloned mice are shown here. The second level combines both the second and third generations, demonstrating the magnitude of the process.
Prof. Blackshaw said the growth of new brain cells has yet to be explained, but initial data makes interesting implications.
"Our data suggests that these neurons may have an important role in regulating feeding."
