设法使鼠在癌细胞肆虐时发光,在癌被药物抑制时变暗,能帮助人们检验抗癌新药的有效性。斯坦福科学家将荧火虫基因插入人体肿瘤细胞,再将此细胞注入鼠体。肿瘤细胞存活时,荧火虫基因发光。用超灵敏摄像机穿过鼠的表皮和组织探测荧光,在计算机屏幕上显示成鼠身上的彩色斑点。实验 Trying to make the mouse glow when the cancer cells havoc and darkening when the cancer is inhibited by the drug can help people test the effectiveness of new anti-cancer drugs. Stanford scientists will firefly gene into human tumor cells, and then injected into the mouse cells. When the tumor cells survive, the firefly gene shines. With ultra-sensitive camera through the mouse’s epidermis and tissue to detect fluorescence, on the computer screen shows a mouse into the body of the color spots. experiment
