⏰ 每週三分鐘吸收一個科學新知： 最近，科學家真的在實驗室裡「造出卵子」了而且是用人類皮膚細胞！😳 美國奧勒岡健康與科學大學團隊利用皮膚細胞成功製造出「功能性卵子」，這項研究登上《自然·通訊》，被視為可能改寫生殖醫學的革命性突破。 靈感來自「複製羊桃莉」：研究人員把皮膚細胞的細胞核（含46條染色體）放進一顆移除遺傳物質的卵子裡，再用特殊藥物「欺騙」卵子進行減數分裂，讓它只留下23條染色體，成功變成能受精的卵子。 更令人震驚的是，這些人工卵子真的能與精子結合、發育成早期胚胎！雖然實驗因倫理規範在第六天中止，但這已是人類首次跨出「以皮膚創造生命」的關鍵一步。 未來，這項技術或許能幫助不孕症患者、癌症治療後的女性，甚至讓同性伴侶擁有雙方血緣的孩子。不過，染色體錯配與倫理爭議仍是巨大挑戰。我們該如何安全、合乎倫理地使用這項技術，將是全人類需要共同面對的課題。 👀想知道更多嗎？快收聽「三分鐘科學快訊」EP138，或翻閱 2025年10月1日《科學人》專題報導別錯過這場生命起源的實驗室革命！ #免疫系統 #T細胞 #Treg #FoxP3 #免疫煞車 #自體免疫 #癌症治療
