derivation of hematopoietic stem cells from murine embryonic stem cells

<p class="jove_content">干细胞被定义为一个有能力的细胞自我更新和产生多个不同的后代。胚胎干细胞（ESC）上都来源于早期胚胎的囊胚differentiative能力的多能干。其巨大的differentiative潜力，使他们推断如何哄他们产生临床上有用的细胞类型为中心的许多研究的重点。成功，造血干细胞从小鼠ESC（HSC）的推导，最近已经完成，可以在这个视频协议的可视化。 HSC的，可以说是最临床上利用的细胞群，是用来治疗无数的造血系统恶性肿瘤和障碍。然而，许多患者可能会受益于HSC的治疗得不到合适的捐赠者。 ESC键可以为这些患者提供替代来源的HSC。以下协议，建立了从ESC - HSC，可以研究，并告知努力找出人类胚胎的HSC的基线。在这个协议中，ESC 6天市售的血清前筛选最佳的造血分化的胚状体（EBS）是有区别的。分化是再分解，与逆转录病毒HOXB4感染。感染的EB -源性细胞接种于OP9基质，派生从颅骨的M - CSF - / - 小鼠骨髓基质细胞系，并合作培养中存在的十天，促进细胞因子的造血。在这种合作文化，被感染的细胞大大扩大，在一代人造成了数百万个细胞100S异构池。然后，这些细胞可以用于救援和重建致死剂量照射的小鼠。</p>
