進入《中英對照讀新聞》Fatty skin cell clue to baldness 肥胖的皮膚細胞是禿頭線索
◎國際新聞中心
Fat cells in the skin have been identified as the source of chemicals needed to make hair grow, according to researchers in the US. Experiments on mice, reported in the journal Cell, suggested hair stem cells were controlled by fat.
根據美國研究人員表示，皮膚的脂肪細胞已被認定是頭髮成長必需的化學物質來源。「細胞」期刊刊登的老鼠實驗顯示，頭髮幹細胞是由脂肪控制。
Injecting a type of fat cell stimulated hair growth in mice which otherwise struggled to grow hair. The Yale University team says it may be possible to use the findings to one day restart hair growth to reverse balding.
注射一種脂肪細胞可刺激有生髮困難的老鼠頭髮生長。耶魯大學團隊說，有朝一日，這項發現或能重啟頭髮生長，來扭轉禿頭。
They said there was a four-fold increase in the number of "precursor" fat cells in the skin around a hair follicle when it started to grow. They looked at defective mice which could not produce these fat cells. Hair normally grows in cycles, but in the defective mice - the follicles had become trapped in the dormant phase of the cycle.
他們說，頭髮毛囊開始生長時，周圍皮膚的「前驅」脂肪細胞數量呈4倍增加。他們觀察不能製造這些脂肪細胞的有缺陷老鼠。頭髮通常有生長循環，但缺陷鼠的頭髮毛囊卻陷入停滯期。
Scientists injected fat cells from healthy mice into the defective mice. Two weeks later, hair follicles had started to grow.
科學家將健康老鼠的脂肪細胞，注射到有缺陷的老鼠體內，兩周後，頭髮毛囊開始生長。
