解密,蠑螈的再生之謎
許多蠑螈可以很容易地再生失去的肢體,但成年哺乳動物,包括人類,并不能。為什么會出現這種情況是一個科學謎團,數千年來一直吸引著自然界的觀察者。 現在,緬因州巴爾港MDI生物實驗室的James Godwin博士領導的一個科學家團隊,通過發現促進高度再生蠑螈axolotl再生的分子信號差異,同時阻斷

促脊髓再生的基因伴侶-揭示脊髓損傷修復研究新方向
海洋生物實驗室(MBL)的科學家最近已經確定了axolotl salamander(一種蠑螈)中的基因“伙伴關系”——當它們被激活時,能夠在嚴重脊髓損傷后讓神經管和相關神經纖維實現功能性再生。有趣的是,這些基因也存在于人類中,可惜它們是以不同的伙伴關系被激活。該研究結果發表在本周的Nature
