If the gene therapy could make the white hair of an albino mouse turn black, it should also help banish gray hair - without dyes. 如果基因療法能使患白化病的老鼠毛發(fā)變黑，那不用染發(fā)劑而使用基因療法也應該有助于消除灰白頭發(fā)。
The possibility of tinkering with the scalp's genes to prevent the onset of graying gained momentum four years ago when scientists made an albino mouse turn black in one patch. 四年前，科學(xué)家已經(jīng)可以使患白化病的老鼠的一小塊皮毛變黑，這為研究修補頭皮基因來(lái)防止頭發(fā)變灰的可能性提供了動(dòng)力。
