科普專欄–薯不揀單 - 深入淺出–利用受精雞蛋作癌細胞研究

癌症研究中，很多時候都會將癌細胞注入在老鼠身內，然後再試驗各種藥物，認證在實驗室細胞中所獲得的結果。609Please respect copyright.ＰＥＮＡＮＡCTw0mrnEK1

除了老鼠、兔、魚、狗、蟲等動物外，受精雞蛋亦是一款常用的實驗模型。609Please respect copyright.ＰＥＮＡＮＡ55an41DXZm

（圖2）受精雞蛋中存有氣囊以及充滿血管系統的外膜，提供了一道營養充足的環境。那外膜的名稱為chorioallantoic membrane (CAM) ，因而這款動物模型亦稱之為CAM model。609Please respect copyright.ＰＥＮＡＮＡtiwMkACKSh

在受精蛋誕下的第15日前，淋巴系統尚未完善建立，不存在免疫衝突問題，因此適合移植人類癌細胞之用。609Please respect copyright.ＰＥＮＡＮＡALerXIj1dF

同時胚胎痛楚接收系統在第15日前未完整建成，若然能在第15日前完成實驗，道德爭議的問題亦相對減低。609Please respect copyright.ＰＥＮＡＮＡooIkGXHwCN

（圖3）從圖中可見，癌細胞會在血管上形成腫瘤，同時癌細胞（綠色螢光）會透過血管轉移到雞蛋各部份，甚至聚居到胚胎的肺部及腎臟位置。609Please respect copyright.ＰＥＮＡＮＡPSzPnm3fja

此方法可同時驗證藥物對於癌細胞繁殖及轉移能力的影響，名副其實的一雞兩味。609Please respect copyright.ＰＥＮＡＮＡNt9sikKAQ8

亦有研究嘗試推展把真實病人的癌細胞樣本移植到CAM model，再試用不同藥物在其上，希望藉此能找出一款最為適合醫治該病人的藥物或方法。609Please respect copyright.ＰＥＮＡＮＡgmreGvs68a
