自然法則下，大多數的不同物種均不能互相交配。544Please respect copyright.ＰＥＮＡＮＡCbGMk2Y0a4

儘管如此，近日有科學家「成功」嘗試把人類的幹細胞注入到猴子的胚囊裡頭，有部份的混種細胞更成功生存及繁殖19日之多。544Please respect copyright.ＰＥＮＡＮＡNc7rDkkJOP

(圖2)從圖中可見，當人類的幹細胞注入到猴子的胚囊後，科學家便將「混種細胞」在體外的實驗室培植器皿飼養，並不斷觀察兩種細胞的繁殖去向。544Please respect copyright.ＰＥＮＡＮＡRGSqua9waN

(圖3)研究人員共嘗試注射人類幹細胞到132個猴子胚囊裡頭，隨著日數增加，胚胎的存活裡亦有所遞減。544Please respect copyright.ＰＥＮＡＮＡ2fMx9H9jv9

13日後，存活下來的胚胎僅只剩下3個。544Please respect copyright.ＰＥＮＡＮＡ5PUwRYsHLU

數字上無疑是一道失敗，但在整個過程中，人類的幹細胞的確是能夠在猴子胚囊繁殖及演化，證實人類幹細胞有能力在其他物種的胚胎細胞生存。544Please respect copyright.ＰＥＮＡＮＡ8SeirgMDW8

為何要做這種實驗?544Please respect copyright.ＰＥＮＡＮＡflAeG5wBiU
544Please respect copyright.ＰＥＮＡＮＡgK63pe8Rtt
初心是希望透過其他物種發展人體器官，作醫學治病用途。544Please respect copyright.ＰＥＮＡＮＡDf6OOsZJwc
現今已有不少研究在體外實驗室培植皿上發展類近器官的結構，但對比確實在動物體內的環境裡，效率及性能暫時來說始終是無法比得上。544Please respect copyright.ＰＥＮＡＮＡ1MOL7fPd7I
544Please respect copyright.ＰＥＮＡＮＡAlRg8rBumY
至於道德倫理方面，這研究無疑是對全世界人士的一道試探。544Please respect copyright.ＰＥＮＡＮＡY5S9XO6GM6
