LIVE／DEAD?FixableDeadCellStainKits
實驗概要The LIVE/DEAD? Fixable Dead Cell Stain Kits use a novel method to evaluate the viability of mammalian cells by flow cytometry. These assays are based on the reaction of a fluorescent reactive dye with cellular amines. The reactive dye can permeate the compromised membranes of necrotic cells and react with free amines both in the interior and on the cell surface, resulting in in......閱讀全文

Cell－Stem－Cell：揭示細胞炎癥記憶機制
當組織經歷炎癥時，它的細胞會記得。在炎癥的高峰期，細胞將蛋白質固定在其遺傳物質上，并將它們在最后斗爭中所處的位置記下來。下次接觸時，炎癥記憶就會啟動。這些細胞利用以前的經驗來更有效地做出反應，即使是對它們以前從未遇到過的威脅也是如此。如果皮膚以前接觸過刺激物，如毒素或病原體，它就會更快地愈合傷口
Cell－Stem－Cell揭示新癌癥干細胞
日前，Lawson健康研究所的研究人員在結腸中鑒定到了與癌癥生長有關的新干細胞群體。這項研究發表在Cell Stem Cell雜志上，將給結腸癌研究和治療帶來顯著改變。 結腸癌（colon cancer）是一種常見的消化系統惡性腫瘤，發病率占胃腸道惡性腫瘤的第三位。隨著飲食習慣的改變和人口老齡

Cell－Stem－Cell:－帕金森發病機制新見解
在帕金森等神經退行性疾病中，特定的神經元的死亡會導致患者出現運動問題和其他癥狀。長期以來，科學家們致力于發現這些神經元死亡的原因。 最近，來自洛克菲勒大學的研究人員發現，帕金森氏病中受影響的神經元實際上會處于“關閉”而非“完全死亡”的狀態。研究小組發現，這些不死的神經元釋放出的化學物質也會使他
Cell－Stem－Cell：叩開干細胞的家門
人類造血干細胞（HSC）可以通過造血過程生成成熟的血細胞，包括免疫系統的細胞。多年以來，科學家們一直在嘗試解析調控造血干細胞功能和分化的具體機制。但這項工作并不簡單，因為HSC只存在于骨髓的特殊區域（niche），體外培養很難重現這樣的環境。 要對人類造血干細胞進行深入分析，就需要一個能夠移植
Cell－Stem－Cell：皮膚是突變的戰場？
正常皮膚含有混雜的突變細胞，但很少有最終形成癌癥的，科學家現在發現了原因。劍橋大學桑格研究所和MRC癌癥研究所的研究員通過基因工程小鼠，發現皮膚組織中的突變細胞會相互競爭，只有適者才能生存。 9月27日發表在Cell Stem Cell雜志上的研究結果顯示，人類正常皮膚對癌癥的抵抗力比之前想象
Cell－Stem－Cell發表重編程重要成果
再生醫學旨在通過細胞移植替換人體內受損的細胞、組織和器官，是一個發展迅速的新興領域。胚胎干細胞（ESC）能夠形成胎兒體內所有類型的細胞、組織和器官，被視為細胞治療的寶貴資源。然而ESC在實際應用中遭遇了兩大瓶頸，免疫排斥和倫理問題。 細胞重編程可以繞過人類胚胎干細胞的倫理爭議，近年來受到了廣泛
Cell－Stem－Cell綜述：干細胞免疫調控
免疫系統是我們機體對抗入侵病原體的第一道防線，也是組織發展，內環境穩態和傷口修復不可或缺的一部分。近年來，科學家們已越來越認識到免疫系統中的細胞和體液成分也有助于損壞組織的再生，比如四肢、骨骼肌肉、心臟和中樞神經系統中出現的損傷，因此在這一方面進行了大量的研究。 7月Cell Stem Ce
Cell－stem－cell：純化人類細胞新技術
多能干細胞研究之所以流行是因為在生物醫學研究中，多能干細胞能夠分化為任意細胞類型。但一些代表性的分化方法會導致異質性細胞群體的出現，這時候就需要將目的細胞進行純化分離。 目前對這類細胞進行分離主要根據細胞表面的特征性受體不同，利用抗體進行分離篩選。但在一些情況下，這種分離方法的純化水平很低，并
