自然法則下,大多數的不同物種均不能互相交配。391Please respect copyright.PENANAeLdapijpnk

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。391Please respect copyright.PENANAr5TuruzcWa

(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。391Please respect copyright.PENANAXZ4XscheFC

(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。391Please respect copyright.PENANAVlTeE8cm1w

13日後,存活下來的胚胎僅只剩下3個。391Please respect copyright.PENANAFgkPgVlJMv

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。391Please respect copyright.PENANAFoQj3jJqI1

為何要做這種實驗?391Please respect copyright.PENANAmfKJ7Gg5aa
391Please respect copyright.PENANAlJWTU2kFUK
初心是希望透過其他物種發展人體器官,作醫學治病用途。391Please respect copyright.PENANAf76PCck0yq
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。391Please respect copyright.PENANA7eQRNUv4Jy
391Please respect copyright.PENANAMU4zZJ1hj7
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。391Please respect copyright.PENANAllGyD7nMc2
