癌細胞轉移，即是從原來的位置轉移到另一地方。472Please respect copyright.ＰＥＮＡＮＡ3He1Jnd7CP

利用老鼠作為癌細胞轉移研究的話，科學家又是如何得知癌細胞是否有出現轉移的過程，以及所轉移的地方呢?472Please respect copyright.ＰＥＮＡＮＡhOo6vBwxsO

（圖2）探知癌細胞轉移而又不需殺害老鼠的其中一道手段，就是藉助螢火蟲的螢光素酶幫助。472Please respect copyright.ＰＥＮＡＮＡzzoUqguXCb

螢光素酶(Luciferase)能夠將螢光素(Luciferin)轉化成為另一物質，同時亦會發出螢光。472Please respect copyright.ＰＥＮＡＮＡqh1g7xPXYh

換句話說，利用分子生物學技術強迫癌細胞表達螢光素酶的話，當他們遇上螢光素的時候，便會在其所在的位置發出螢光。472Please respect copyright.ＰＥＮＡＮＡEcMWhgMeFW

（圖3）往老鼠移植含螢光素酶的癌細胞，到達需要進行研究時間的時候便為牠們注射Luciferin，Luciferin會經由血液循環系統走遍全身，過一段時間後再對牠們進行麻醉，並用儀器探測螢光，便可以得知癌細胞的大小及所在位置。472Please respect copyright.ＰＥＮＡＮＡYD9gYrZL8t

將右圖對比左圖，便可清晰得知右圖的癌細胞出現了轉移。將此螢光方法配合藥物或基因改造手段，便可得知所對應的醫學方法能否修成正果。472Please respect copyright.ＰＥＮＡＮＡpKEJp9H1uw
