【英语时差8,16】智齿干细胞（下）

The gene¹ manipulation procedure does appear to work in cells taken from the pulpy² tissue of extracted wisdom teeth. Scientists in Japan working with wisdom teeth from three donors⁴ were able to create several stem cell lines. In the lab, many of the cells thrived and responded readily when the researchers prodded⁵ them to turn into different cell types. It may even be possible to freeze and store wisdom teeth to use years later if the donor³ needs an infusion⁶ of stem cells. More research needs to be done before stem cells harvested from wisdom teeth would have a significant real world impact. But the promising⁷ early results suggest that wisdom teeth may become quite useful after all.
