Summary:
A set of new stem cell lines will make it possible for researchers to explore ten different genetic disorders—including muscular dystrophy, juvenile diabetes, and Parkinson's disease—in a variety of cell and tissue types as they develop in laboratory cultures. Researchers led by Howard Hughes Medical Institute investigator George Q. Daley have converted cells from individuals with the diseases into stem cells with the same genetic errors. These newly-created stem cells will allow researchers to reproduce human tissue formation in a Petri dish as it occurs in individuals with any of the ten diseases, a vast improvement over current technology. Like all stem cells, these disease-specific stem cells grow indefinitely, and scientists can coax them into becoming a variety of cell types.
