CultureofHumanEmbryonicStemCells(hESC)

All cell lines are initially grown according to the supplier's protocols but we are adapting them to one simple protocol outlined below:6-well plates (Falcon Cat #353046) are coated for 20 to 60 minutes at room temperature with 0.1% gelatin (Sigma Cat #G1890) in dH2O.Mouse embryonic fibroblasts (CF1 strain), cultured in MEF medium, are mitotically inactivated by treatment with 10μg/ml mitomycin C (Roche Cat ......阅读全文

Stem-Cells:癌症干细胞的新调控机制

  肺癌是一种非常普遍的人类恶性肿瘤,也是造成癌症死亡的头号杀手。肺癌主要分为小细胞肺癌(15%)和非小细胞肺癌(85%)两大类,其中非小细胞肺癌与吸烟高度相关,而且生存率很低。近十年来肺癌发病率在中国攀升得很快,这主要是因为吸烟人数快速增加(大多是男性)。  许多科学家认为,完全治愈肺癌需要靶标癌

使用CO2恒温摇床解决人胚肾-293-(HEK293)-细胞结团问题

人胚肾 293 (HEK293)  细胞在重组蛋白表达中是最常见的宿主细胞。 这类细胞能够表达大量的膜蛋白,如 G 蛋白偶联受体  (GPCR) ,是无法在最常见的生物制药生产宿主,如:中国仓鼠卵巢 (CHO) 细胞中作表达。 HEK293 虽然是蛋白表达的极好宿主,然而 HEK293 细胞

促进人胚胎干细胞长期生长新材料成功面世

  一旦干细胞发生足够增殖而达到预定的目的,这些凝胶能够被冷却而使得这些干细胞从支架上脱落下来,同时不会遭受损伤.这种新的方法优于现存的通过机械或化学方式分离细胞的技术,而且这些现存的技术有更大的风险对细胞造成损伤.科学家们说,这种新材料可能能够让干细胞高效地大量增殖,同时不会因粗心大意而发生污染的

诱导多能干细胞(Induced-Pluripotent-Stem-cells,iPS)

2006年日本京都大学山中伸弥领导的实验室在世界著名学术杂志《细胞》上率先报道了诱导多能干细胞(Induced Pluripotent Stem cells,iPS)的研究。他们把Oct3/4、Sox2、c-Myc和Klf4这4种转录因子引入小鼠胚胎或皮肤纤维母细胞,发现可诱导其发生转化,产

Stem-Cells-Dev:发现骨形成的新型调节因子

  研究人员发现了小鼠体内一种新的转录因子可以帮助调节间充质干细胞(mesenchymal stem cells,MSCs)分化为骨的过程。目前科学家们对于骨细胞分化的研究并不深入,而MSCs则是再生医学领域一种很有潜力的干细胞来源。图片来源:Stem Cells and Development  

Stem-Cells:骨骼用药保护干细胞免受老化影响

  一个突破性的研究发现,干细胞可以通过一种目前用于治疗骨质疏松症患者药物来防止老化的影响。  来自谢菲尔德大学的科学家发现了一种药物唑来膦酸通过减少DNA损伤能够延长间充质干细胞的寿命。  DNA损伤是最重要的一种老化机制,由此干细胞会失去维护和修复组织的能力。  开创性的研究显示,药物保护干细胞

关于单倍体胚胎干细胞的基本信息介绍

  近年来,单倍体胚胎干细胞(Haploid Embryonic Stem Cells, haESCs)的研究得到了非常广泛的关注。单倍体胚胎干细胞指只含有一套染色体,但拥有类似于正常干细胞分裂分化能力的细胞群。根据诱发方式不同,主要分为两种类型:孤雌单倍体胚胎干细胞(parthenogenetic
