Cell Stem Cell:首次在肝脏内将导致肝病的细胞转化为功能性的肝细胞

2016-06-06 佚名 生物谷

干细胞研究取得的进展使得在实验室培养皿中能够将病人的皮肤细胞转化为心脏细胞、肾脏细胞和肝细胞等,这就给科学家们提供希望:有朝一日,这些细胞能够替换器官移植用于治疗器官衰竭病人。但是将这些细胞成功地移植到病人的功能衰竭的器官中仍然是一个重要的临床挑战。如今,来自美国加州大学旧金山分校和德国海德堡大学医院的研究人员在小鼠体内证实在肝脏内产生健康的新的肝细胞是可能的,这就使得细胞移植是不必要的。

干细胞研究取得的进展使得在实验室培养皿中能够将病人的皮肤细胞转化为心脏细胞、肾脏细胞和肝细胞等,这就给科学家们提供希望:有朝一日,这些细胞能够替换器官移植用于治疗器官衰竭病人。但是将这些细胞成功地移植到病人的功能衰竭的器官中仍然是一个重要的临床挑战。

如今,来自美国加州大学旧金山分校和德国海德堡大学医院的研究人员在小鼠体内证实在肝脏内产生健康的新的肝细胞是可能的,这就使得细胞移植是不必要的。更重要的是,他们是将肝脏内导致肝病的细胞(即肌成纤维细胞)转化为健康的新的肝细胞,因而同时降低肝脏损伤和改善肝脏功能。论文通信作者、加州大学旧金山分校外科教授Holger Willenbring说,这一方法采用一种已在利用肝脏靶向基因疗法治疗病人中获得早期验证的病毒基因运送技术,这提示着它可能很容易进行临床转化,用于治疗肝病患者。相关研究结果发表在2016年6月2日那期Cell Stem Cell期刊上,论文标题为“In Vivo Hepatic Reprogramming of Myofibroblasts with AAV Vectors as a Therapeutic Strategy for Liver Fibrosis”。

Willenbring说,“该方法如此有效的部分原因是肝脏是一个具有自然再生能力的器官,因此它能够非常好地适应新的细胞。我们观察到转化后的细胞不仅在功能上整合进肝脏组织中,而且也能够分裂和增殖,从而导致新的肝脏组织块产生。”

在美国,超过60万人遭受终末期肝病或肝硬化的折磨。唯一可用的治愈方法就是肝脏移植,但是供者肝脏短缺意味着在美国每年只有6***受益于这种疗法,而超过3.5万人因这种疾病死亡。 肝纤维化是肝脏渐进性形成瘢痕组织,是肝脏疾病的主要触发因子。当肝细胞不能够足够快速地再生而赶不上酒精等有毒物质或丙型肝炎或脂肪肝等疾病导致的损伤时,肝纤维化就产生了。肌成纤维细胞(myofibroblast)填充肝细胞死亡后留下的空隙,形成类似瘢痕组织的纤维化组织。

肝纤维化发展过程缓慢,但是能够导致严重的肝功能衰竭:一个人在25岁感染上丙型肝炎病毒(HCV),可能在几十年内感觉很好,然后在50岁时突然开始经历疲劳、昏眩、恶心、挫伤、腹泻和黄疸,这表明终末期肝病开始发作。原因在于只要肝脏有至少20%是功能性的,它就能适应,但是一旦它低于这一临界阈限,病人通常在两年内死亡。

在小鼠体内降低肝脏损伤和增加肝脏功能

Willenbring致力于利用干细胞生物学技术产生新的肝细胞(比如,由病人的皮肤细胞转化而来)以便能够替换组织移植来治疗肝脏衰竭。然而,未预料到的是,当Willenbring和他的实验室接近实现这一梦想时,他不得不意识到这种细胞疗法可能不能用于治疗绝大多数肝脏衰竭患者,这是因为肝脏内纠缠在一起的纤维化组织本身会破坏移植细胞的成功定植。

因此,在过去5年,Willenbring和他的团队与来自海德堡大学医院的Dirk Grimm博士及其团队密切合作,着手研究一种不同的方法:在肝脏内,将导致肝纤维化的肌成纤维细胞转化为健康的新的肝细胞。

之前的研究已鉴定出基因调节蛋白混合物能够将其他类型的细胞转化为肝细胞,但是研究人员需要一种方法将这些指令运送到肌成纤维细胞中。在多年的研究后,研究人员鉴定出一种腺相关病毒(adeno-associated virus, AAV)亚型AAV6能够特异地感染肌成纤维细胞。因此,研究人员着重关注AAV,这是因为已证实它在早前的人基因疗法临床试验中是安全的和有效的。

研究人员在肝病小鼠体内证实装填上改变细胞命运的混合物的AAV6确实感染肌成纤维细胞,并且将它们转化为功能性的肝细胞。新产生的肝细胞数量相对较少---不到接受治疗的小鼠体内所有肝细胞的1%,但是这仍然足以降低肝纤维化和改善肝脏功能。

研究人员说,在培养皿中,这种病毒方法也高效地将人肌成纤维细胞转化为功能性的肝细胞,但是还需要开展更多研究以便让这种方法也能用于病人体内。特别地,Willenbring实验室正在努力将这种方法中所使用的混合物包装到单个病毒中,以便降低潜在的副作用和简化临床开发。该实验室也正在努力将让AAV6病毒对肌成纤维细胞的特异性变得更强,这是因为在当前的这项研究中,该病毒也能够感染肌细胞和免疫系统中的一些细胞,不过不能将它们转化为肝细胞,而且也不会明显地影响它们的功能。

Willenbring说,这些新的结果提示着在发生纤维化的肝脏中,相比于细胞移植方法,这种方法可能能够更加高效地和稳定地改善肝脏功能,并且补充道,一旦病毒包装得到优化,这种疗法可能能够在众多医学机构中低成本地开展,而不仅仅是在能够开展干细胞移植的专科医院中开展。

Willenbring是第一个承认这种新技术并不能替换当前的标准肝病疗法:“肝脏移植仍然是最好的治疗选择。但是如果它能够将肝脏功能提高百分之几,那么这就有希望让病人的肝脏功能维持在临界阈值之上,而这可能意味着多活几十年。”

Nature:人皮肤细胞可变身功能性肝细胞

再生医学的力量使得科学家们现在能够将皮肤细胞转化为与心脏细胞、胰腺细胞甚至神经元非常相似的细胞。然而,事实证明拯救生命疗法的重要前提条件:获得完全成熟的细胞生成方法比想象中要困难得多。现在,来自Gladstone研究所和加州大学旧金山分校(UCSF)的科学家们取得了一项重大的突破:他们发现了一种方法可将皮肤细胞转化为成熟的、全功能的肝细胞,甚至在移植到模拟肝衰竭的实验室遗传修饰动物体内后也能自身旺

药物研发史上里程碑式的进展——科学家可无限制的生产功能性肝细胞

肝脏在人体代谢过程中起着重要的作用。作为消化道的“门卫”,肝脏负责药物的降解,因此成为了最易由于药物过量或滥用而受损的器官。评估药物诱导性肝损伤是研发药物的重要部分,必须对人体干细胞进行研究实验。遗憾的是,人类干细胞的供应很少,仅能从捐赠的器官中分离获得。现在,发表于《肝脏病学杂志 》的一项研究表明,科学家已成功通过人胚胎干细胞和基因功能诱导出大量有功能的肝细胞。“这是药物研发史上一个革

Cell Stem Cell:视网膜色素上皮细胞具有干细胞特征

   视网膜色素上皮(retinal pigment epithelium,RPE)细胞是一种单层细胞,位于神经视网膜和血管脉络膜血管层之间,支撑着神经视网膜。视网膜色素上皮的退化可以引发多种疾病,如老年黄斑变性和色素性视网膜炎,甚至可以引起失明。目前对这些疾病治疗方法有限,找到一种新的方法刺激视网膜色素上皮的修复是非常必要的。近日,美国纽约Rensselaer神经干细胞研究所Sally

发现氢化珊瑚钙或可防治脂肪肝

随着人们生活水平的提高和膳食的改变,高脂饮食导致的肝细胞脂肪变性发生率急剧升高。日前,西安交通大学刘健康团队发现,采用氢气缓释剂—氢化珊瑚钙可有效防治高脂饮食所致的大鼠脂肪肝;而同样在高脂饮食条件下,阿尔茨海默氏症(AD)转基因小鼠的肝脏脂肪合成显着抑制,并不形成脂肪肝,但显着推进血糖升高和胰岛素抵抗发生。相关研究分别发表在《神经化学杂志》和《生化药理学》。 研究发现,氢化珊瑚钙在体外和在体

Nat Immuo:“外体”(Exosomes )或可成为抗病毒新药

  复旦大学上海医学院基础医学院教育部袁正宏研究员课题组,历经4年研究发现,肝非实质细胞分泌的“外体”,在干扰素-α的诱导下,可转运到易受病毒感染的肝细胞中,发挥抗病毒作用。这一新机制的发现,对开发治疗慢性乙肝和其他病毒感染性疾病的新药有重要意义。该研究论文7月7日在线发表在国际期刊《自然·免疫学》上。   “外体”是一种由细胞主动分泌出的、大小介于30纳米~100纳米的微囊结构,在细胞

Cell:Hippo通路可能是成熟肝细胞转变干细胞的开关

在美国,每10个人中就有一个人是肝病患者。从目前的诊断和治疗方法来看,有保持水分、用药或器官移植是通常的治疗方法。一群来自哈佛干细胞研究所(Harvard Stem Cell Institute ,HSCI),由Fernando Camargo领导的科学家,日前发现成熟的肝细胞转化为干细胞的方法,他们称未来可通过该方法来治疗肝脏疾病。相关研究发表在Cell杂志上。事实上,去年第二军医大学干细胞与医
