That’s the goal of XenoTherapeutics, a Boston-based biotech nonprofit.
Last week, the US Food and Drug Administration approved the group’s
initial application for temporary skin grafts curated from genetically
modified pigs. This means that they can start testing pig skin grafts on
people who have experienced severe burns. It’s the first time that an
animal organ has been cleared for human testing in the US.

Südhof教授、知名意况毒农学及神经类器官专家EllenFritsche教授就类器官钻探的现状、瓶颈、应用价值以及今后的腾飞大方向进行阐述。下边将为读者显示访问内容。

类器官(Organoids)是一种在体外情状下培养而成的拥有三维结构的微器官,具有类似真实器官的繁杂结构,并能部分模拟来源组织或器官的生理功用。借助类器官,探讨人口可深刻考察肉体组织的扭转,更加好地精通发育进度,并可用以再生农学以及药品的疗效筛选。由此,类器官切磋具有广泛的发展前景。

Skin, the body’s largest organ, plays a crucial role in the immune
system by blocking pathogens from reaching our vulnerable internal
organs. It also holds in water, electrolytes, and other nutrients, and
helps the body maintain a constant temperature. People with severe skin
damage are at a high risk of developing deadly infections or organ
failure as a result of changes in temperature or hydration.

    EllenFritsche答:类器官是一种在体外培养而成的具备来源器官显微解剖特征的多细胞三维结构。迄今截止,差别团体、病痛模型及模拟发育的类器官已出版。类器官的工具细胞首要为公司特异性多能干细胞。类器官的显要特点包含基于细胞类别的本人组织及空间范围的定向区别,与体内发育进度相似。他们(类器官)含有各种器官特异性细胞,这么些细胞的空间组织、排列与来自器官类似。别的,他们(类器官)具备局部源于器官特有的成效。迄今,来源于多种器官的类器官业已应际而生,包罗脑、肠道、胃、舌、甲状腺、胸腺、睾丸、肝脏、胰腺、皮肤、肺、肾、心脏及视网膜。除了来自健康组织的类器官,大批量毛病模型(包蕴肿瘤模型)的类器官也不断涌现。最后,类器官为实验研商职员进行生长生物学钻探提供了绝佳模型。
    Ellen Fritsche’s answer:An organoid is a three-dimensional (3D),
    multicellular structure with microanatomical features of the organ of
    origin produced in vitro. So far, organoids of different tissues,
    disease models, as well as organoids resembling development have been
    created. Cellular basis for organoids are mainly pluripotent or
    tissue-specific stem cells. Key features of organoids include their
    self-organization through cell sorting and spatially restricted lineage
    commitment in a manner similar to in vivo. They contain multiple,
    organ-specific cell types which are spatially organized in a manner
    similar to the organ. In addition, they recapitulate some specific organ
    functions. Organoids from multiple organs have so far been created.
    These include brain, intestine, stomach, tongue, thyroid, thymus,
    testis, liver, pancreas, skin, lung, kidney, heart and retina. In
    addition to the healthy organoids, a plethora of disease models
    including tumor models, have been developed. Last, organoids offer
    researchers an exceptional model to study developmental biology.
  2. 问:可以还是不可以谈谈类器官在生物工学领域的第一选择?
    Question:What are the main applications of the organoids in the field
    of biomedicine?
    托马斯 C.
    Südhof答:类器官的价值在于其具备在体外作育意况下构建人类器官病痛模型的潜在的力量。那可怜适用于像心脏这样的团体,在人类开始时代脑发育的商量上也日渐变得低价。但类器官在再生艺术学上的运用依然前路漫漫。
    Thomas C. Südhof’s answer:The attraction of organoids is that they
    potentially allow disease modeling of human organs in a dish. This works
    best for tissues such as heart, and is becoming feasible for early human
    brain development. The use of organoids in regenerative medicine is
    still far in the future.
    埃伦Fritsche答:作为一项根本的技能突破,类器官近年来已被公众认同为生物切磋的机要工具,并负有主要的医治应用价值。类器官允许在三个模仿内源性细胞协会和器官社团的景况中举办协会生物学、发育、再生、病魔建立模型(富含癌症研讨)、器官移植技艺改良、药物发掘/医疗效果评估以及毒文学的商讨。
    Ellen Fritsche’s answer:Starting as a major technological breakthrough,
    organoids are now well-established as an essential tool in biological
    research and also have important implications for clinical use.
    Organoids allow research on tissue biology, development, regeneration,
    disease modeling (including cancer research), improvements in organ
    transplantation, drug discovery/response as well as toxicological
    studies in an environment that mimics endogenous cell organization and
    organ structures.
    3.
    问:在肿瘤生物学及新药开垦世界,类器官相对于细胞系、动物模型的要紧优势在何地?
    Question:What are the main advantages of using organoids instead of
    cell lines, or animal models in the field of tumor biology and new drug
    development?
    托马斯 C.
    Südhof答:绝对于细胞系来说,类器官营造了贰个持有三个维度结构的器官样协会,就算并不完全(模拟人类器官)。相较于动物模型,类器官的优势展现在其促成了选用人源性协会议及展览开试验商量。
    Thomas C. Südhof’s answer:The advantage over cell lines is that
    organoids model a three dimensional organ, although not completely. The
    advantage over animal models is that organoids enable studies of human
    material.
    Ellen Fritsche答:古板的二维 (2D)
    肿瘤细胞系作育和动物人源性肿瘤异种移植物 (PDTXs)
    一直以来一向被用作肿瘤模型, 并为癌症斟酌做出了伟大贡献。可是,
    种种短处阻碍了那一个模型的看病使用,那至关心注重假诺由于与肿瘤临床相关的药物开荒是成功率最低的。二维细胞作育种类不负有免疫细胞、微遭遇、间质成分和五脏六腑特异性的功能。其余限制包罗肿瘤细胞系经每每传世后缺少来源肿瘤的遗传异质性,
    原因是细胞在作育皿二维持生活长的景况下会生出优势克隆接纳,但那并不切合生理。其它,
    PDTX 模型还经历了小鼠特异性的肿瘤演变。在财富方面,
    这几个模型也是不过的费钱费时。类器官能够制服在那之中的一部分限量。类器官的基因修饰可达成在看似生理条件的事态下开始展览病痛建立模型。比如,
    将肿瘤性突变导入健康干细胞能够发生遗传决定的肿瘤类器官。别的,
    类器官能够从病人来自的寻常组织和肿瘤组织中飞速培养,进而使病人特异性药物检验和性子化治疗方案的付出成为只怕。在这种伤者特异性的瘤子类器官中,可观看到集体稳态(histostasis),如3D作育保留了与来自伤者肿瘤相平等的团协会病艺术学特征,为前途脾气化肿瘤医治的开荒进取提供了希望。与
    PDTX 差别,类器官维护方便,具有整合免疫性细胞的或许性,易实行基因改变(遗传性肿瘤建立模型),帮助同盟对照的钻研,并可用来MediaTek量药物筛选和生物库的建设。
    除此之外肿瘤学,
    类器官也为新药开荒提供了绝佳模型。新药开辟的失利率异常高,那在早晚水准上是出于动物药代重力学和药效学的出入或动物病痛模型并不能够完全模仿人体病理进度。具备人体特别生理和病理特点的类器官有利于战胜这么些难点。基于特定病痛,乃至一定个人,以色列德国州仪器量形式作育的类器官推测将发展成为标准治疗的雄强工具。以后可依赖生物库实行筛选,不仅仅是为着剖断新药,还可发表哪些伤者能够从某些(现存)
    药物的医治中收益。其余,对秘密药物的首要检查实验可为制药业提供新的教导。别的,类器官未来恐怕用于毒农学检查实验,
    以作为动物试验的有力补充(要是还是不是部分代表的话)。
    Ellen Fritsche’s answer:Traditional two-dimensional (2D) tumor cell
    line cultures and patient-derived tumor xenografts (PDTXs) in animals
    have long been employed as tumor models and have made tremendous
    contribution to cancer research. However, a variety of drawbacks hamper
    these models for clinical use as success rates for tumor therapeutics
    are lowest in the field of drug development. 2D cell line cultures do
    not contain immune cells, microenvironment, stromal compartments, and
    organ-specific functions. Other limitations include the lack of genetic
    heterogeneity of original tumors after many passages for cancer cell
    lines because clonal selection in the dish happens for superiority in 2D
    growth, which is not physiologic. Moreover, PDTX models experience
    mouse-specific tumor evolution. On the resource side, such models are
    highly money- and time-consuming. Organoids can overcome some of these
    constraints. Genetic modification of organoids allows disease modeling
    in a setting that approaches the physiological environment. Here,
    insertions of tumor mutations into healthy stem cells allow generation
    of genetically-controlled tumoroids. Additionally, organoids can be
    grown with high efficiency from patient-derived healthy and tumour
    tissues, potentially enabling patient-specific drug testing and the
    development of individualized treatment regimens. In such
    patient-specific tumoroids, histostasis is observed, i.e. conservation
    of histopathological traits between 3D cultures and the matched patient
    tumor, promising advances in personalized tumor therapies in the future.
    In contrast to PDTX, organoids are of easier maintenance, bear the
    possibility to integrate immune cells, are amenable to genetic
    modification (genetic cancer modeling), allow study of matched controls,
    can be used for high throughput drug screening and biobanking.
    Besides oncology, organoids are promising models for drug development.
    Attrition rates in new drug development are high. This is partly
    reasoned indifferences between animal pharmacokinetics and –dynamics or
    in animal disease models that do not correctly resemble human pathology.
    Organoids with human-relevant physiology and pathology are thought to
    help overcoming these issues. Organoid cultures based on a specific
    disease and even on a specific individual used in a high-throughput
    manner are expected to develop into powerful tools for precision
    therapy. Future screens may be performed using biobanks with the aim of
    not only identifying new drugs but also revealing which patients may
    benefit from treatment with certain (existing) drugs. In addition,
    focused tests of potential drugs should identify new leads for the
    pharmaceutical industry. Furthermore, organoids may be used in the
    future for toxicology testing to complement, if not in part replace,
    animal testing.

    问:当前类器官的局限是什么?为了满意肿瘤生物学、干细胞生物学、移植、新药开垦领域的钻研需求,类器官需求在哪些方面进一步考订?
    Question:What are the limitations of organoids and what aspects of
    organoids can be further improved to meet the demand for research in
    tumor biology, stem cell biology, transplantation and drug
    development?
    托马斯 C. Südhof答:
    类器官领域的研讨仍在开发银行阶段。纵然对于如心脏和肝脏那样的团协会,类器官也很不成熟,仅能有的模仿人体器官。对于脑组织则更甚。好多中心的(脑协会)生理功用,如细胞生理、生物化学效用仍有待突破。那将花费数年的岁月。
    Thomas C. Südhof’s answer:The field of organoid research is still in
    the beginning. Even for tissues like heart and liver, organoids are very
    immature and only partly model the human organ. This is worse for brain.
    Much fundamental biology, such as cell biology and biochemistry, is
    needed to advance the field. This will take many years.
    埃伦Fritsche答:类器官是融入了各样器官特异性细胞类型、组织形态和遵循的团队模型。但类器官仅为有限度的模拟,干扰那项技艺运用的一个重大限制是它的体量。当类器官体积增添时,缺氧和贫乏可溶性因子所致的团体坏死是亟需解决的主题材料。消除那些题指标多个大概方案是激排毒管生成渠道,
    进而使类器官血管化。这一度在hiPSC衍生的肝脏类器官上成功达成。类器官领域的另二个挑衅在于贰个整机的机体中所自然存在的五脏六腑“对话”。类器官琢磨可满意生物工程的供给,
    通过培育包涵差别体系hiPSC衍生类器官(显示五个器官系统的组织和功能)的器官芯片设备,用以在更类似于体内的条件中筛选药物。别的,通过在类器官中增多免疫性细胞,
    还可模拟具备免疫系统的公司间“对话”。别的,在药理和毒军事学商讨中,物质的肝脏代谢至关心器重要,这可由此以器官芯片的情势富含肝脏代谢来兑现。
    Ellen Fritsche’s answer:Organoids are organ models recapitulating an
    assortment of organ-specific cell types, tissue morphogenesis and
    functions. Yet, there are limitations in their mimicry. One important
    limitation plaguing the application of this technology is their size.
    When the organoids’ volume increases, the issue of tissue necrosis
    caused by the lack of diffusion of oxygen and soluble factors needs to
    be addressed. One solution for this problem might be the activation of
    angiogenic pathways that will lead to vascularised organoids. This was
    already succeeded with hiPSC-derived liver organoids. One more challenge
    of the organoid field lies in organ crosstalk, which is naturally
    present in an intact organism. Here, organoid research meets
    bioengineering by producing organ-on-a-chip devices containing different
    types of hiPSC-derived organoids representing the structure and function
    of multiple organ systems for screening the effects of drugs in more in
    vivo-like settings. The crosstalk of tissues with the immune system can
    be modelled by adding immune cells to the organoids. For pharmacological
    and toxicological applications, liver metabolism of compounds is
    crucial. Including such metabolism via an organ-on-a-chip approach can
    solve this issue.
  3. 问:当前类器官商讨的升华动向怎样?
    Question:What are the current trends for organoids research?
    托马斯 C.
    Südhof答:(当前的现状是)全体人都在盲目追求应用,却不经意了四个结实的不利基础。作者以为以后会有巨额的公司在那边贩售希望,但他俩繁多将以战败告终。因为有关生医学切磋成果并不足以支撑那几个使用类型。类器官最有前景的应用领域应是用以肝脏、心脏和肿瘤的药品筛选。
    Thomas C. Südhof’s answer:Everybody rushes towards applications,
    without a solid scientific basis. I think hundreds of companies will be
    founded that will sell hope, but will mostly fail because the biology
    isn’t there to support applications. Most promising are drug screens in
    tissue organoids such as liver or heart and in cancer.
    EllenFritsche答:近些日子类器官商讨的可行性蕴涵创立用于MediaTek量筛选的类器官库和平台,
    创设其余病症模型,
    以及创建用于全体生物体建立模型的器官芯片和微流体芯片。在此刻意要重申的是作育基的限量亟待化解。对微流体芯片来说,供给一种芯片上有所类器官均适用的通用培育基。其余,依据器官系统的例外,
    须求费用与生理进度有关的来自类器官的MediaTek量数据输出装置。在临床方面,为了支付最好个体化学医学治方案,使用源自病者特异性hiPSC类器官的个体化学医学疗探究须要开始展览。在毒管理学领域,类器官目前已被用来代替动物实行毒性测验。
    Ellen Fritsche’s answer:Current trends for organoid research include
    generation of organoid banks and platforms for high-throughput screening
    approaches, generation of additional disease models, and set up of
    organ-on-a-chip and microfluidics devices for whole organism modeling.
    Here, especially medium constrictions have to be solved. For
    microfluidics a common medium for all organoids on the chip is needed.
    Moreover, depending on the organ system, physiologically relevant
    high-throughput readouts from organoids need to be developed. On the
    clinical side, research on personalized medicine using organoids derived
    from patient-specific hiPSC is warranted for optimal individual
    treatment regimes. In the toxicology field, organoids as substrates for
    toxicity testing replacing animals is currently exploited.
  4. 问:可不可以预测一下接下去5年内类器官研商领域的上扬?
    Question:How the organoids research field will be look like in 5
    years?
    托马斯 C. Südhof答:
    笔者的展望是在接下去的5年内好的实验室将学会怎么促进类器官的老到,并掌握该办法的受制。笔者感到,就算类器官为干细胞商讨提供了了不起的空子,如力促新意识和疗法的面世;但那将开支10年或越来越长的年华来进步。到那时候,也独有到那时候,走向应用能力真正变为可能。在那以前,大批量初创公司将会烧掉数以亿计的开销,他们中的少部分将会走向成功,并找到扩展营业收入的新路径。
    Thomas C. Südhof’s answer:My prediction is that in 5 years, good
    science labs will have learned how to mature organoids and the
    limitations of the approach will have been defined. I think organoids
    are a tremendous opportunity in stem cell approaches that will enable
    novel discoveries and therapies, but that this will take at least 10
    years to develop. Then and only then will it be possible to rationally
    move towards applications. Until then, lots of start-ups will have spent
    hundreds of millions of dollars, and a few of them will have been
    successful in generating some future avenue of revenue.
    EllenFritsche答:在5年内,类器官的遗传操作与类器官库相结合将给生物医研带来颠覆的转变。购买来源于具备不一致遗传背景伤者的病症特异性类器官将变为恐怕。器官芯片平台将全部特定规范,由合同研商集体(CRO)以与当下动物试验类似的点子提供。类器官将巨大地拉动药品医疗效果试验和安全性测量试验的进展,由此也将跻身药物开荒和化学安全性评估切磋的禁锢领域。
    Ellen Fritsche’s answer:In 5 years, genetic manipulation of organoids
    in combination with organoid banking will have revolutionized biomedical
    research. It will be possible to purchase disease-specific organoids
    from broad ranges of patients with distinct genetic backgrounds.
    Organ-on-a-chip platforms will be standard and offered by CROs in a
    similar manner than currently animal testing. Organoids will have
    tremendously facilitated drug efficacy and safety testing and thus will
    have entered also into the regulatory areas of research for drug
    development as well as chemical safety assessment.

XenoTherapeutics, which gets its name from xenotransplantation, or
animal-to-human transplants, has bred pigs that have skin remarkably
similar to our own. Although pig skin normally produces a type of sugar
human skin does not, these pigs have been genetically modified not to
make it. Grafts from these pigs are therefore more likely to slide under
the radar of the host’s immune system—at least temporarily. The idea is
that they could be used for immediate burn treatment, followed human

epidermolysis bullosa.

Ellen Fritsche’s answer:An organoid is a three-dimensional ,
multicellular structure with microanatomical features of the organ of
origin produced in vitro. So far, organoids of different tissues,
disease models, as well as organoids resembling development have been
created. Cellular basis for organoids are mainly pluripotent or
tissue-specific stem cells. Key features of organoids include their
self-organization through cell sorting and spatially restricted lineage
commitment in a manner similar to in vivo. They contain multiple,
organ-specific cell types which are spatially organized in a manner
similar to the organ. In addition, they recapitulate some specific organ
functions. Organoids from multiple organs have so far been created.
These include brain, intestine, stomach, tongue, thyroid, thymus,
testis, liver, pancreas, skin, lung, kidney, heart and retina. In
addition to the healthy organoids, a plethora of disease models
including tumor models, have been developed. Last, organoids offer
researchers an exceptional model to study developmental biology.

长期以来平素被用作肿瘤模型,
并为癌症研究做出了高大进献。然则,各个劣势阻碍了那些模型的看病应用,那根本是出于与肿瘤医治相关的药品开辟是成功率最低的。二维细胞作育种类不持有免疫性细胞、微遇到、间质成分和器官特异性的功用。别的限制包涵肿瘤细胞系经数十次传世后缺乏来源肿瘤的遗传异质性,原因是细胞在作育皿二维持生活长的条件下会时有暴发优势克隆选取,但这并不合乎生理。其余,PDTX

除了那一个之外肿瘤学,类器官也为新药开垦提供了绝佳模型。新药开垦的战败率非常高,那在早晚水准上是由于动物药代引力学和药效学的歧异或动物疾病模型并不可能完全模仿人体病理进程。具备人体非常生理和病理特点的类器官有利于制伏那么些难题。基于特定病痛,以至一定个人,以色列德国州仪器量格局培育的类器官估量将发展成为标准治疗的强硬工具。未来可依据生物库进行筛选,不仅仅是为着决断新药,还可发布哪些伤者能够从某个药物的临床中收益。其它,对秘密药物的机要检查评定可为制药业提供新的辅导。另外,类器官今后恐怕用于毒文学检验,以作为动物试验的雄强补充(就算不是一些代表的话)。

transplant from the boy’s father —to no avail.

Ellen Fritsche’s answer:Traditional two-dimensional tumor cell line
cultures and patient-derived tumorxenografts in animals have long been
employed as tumor models and have made tremendous contribution to cancer
research. However, a varietyof drawbacks hamper these models for
clinical useas success rates for tumor therapeutics are lowest in the
field of drug development. 2D cell line cultures do not contain immune
cells, microenvironment, stromal compartments, and organ-specific
functions. Other limitations include the lack of genetic heterogeneity
of original tumors after many passages for cancer cell lines because
clonal selection in the dish happens for superiority in 2D growth, which
is not physiologic. Moreover, PDTX models experience mouse-specific
tumor evolution. On the resource side, such models arehighly money- and
time-consuming.Organoids can overcome some of these constraints. Genetic
modification of organoids allows disease modeling in a setting that
approaches the physiological environment. Here, insertions of tumor
mutations into healthy stem cells allow generation of
genetically-controlledtumoroids. Additionally, organoids can be grown
with high efficiency from patient-derived healthy and tumour tissues,
potentially enabling patient-specific drug testing and the development
of individualized treatment regimens. In such patient-specific
tumoroids, histostasis is observed, i.e. conservation of
histopathological traits between 3D cultures and the matched patient
tumor, promising advances in personalized tumor therapies in the future.
In contrast to PDTX, organoids are of easier maintenance, bear the
possibility to integrate immune cells, are amenable to genetic
modification (genetic cancer modeling), allow study of matched controls,
can be used for high throughput drug screening and biobanking.

在澳大巴塞尔(Australia)的一个病例,一个7岁的男孩住进了医院,二〇一六年后她的25%的皮层已经脱落。托比亚斯Rothoeft,在波鸿的鲁尔学院的一名夜盲科医教师道德意志说,他和她的同事们品尝了全方位——包含男孩老爸的皮层移植——但都不算。

Besides oncology, organoids are promising models for drug development.
Attrition rates in new drug development are high. This is partly
reasoned indifferences between animal pharmacokinetics and –dynamics or
in animal disease models that do not correctly resemble human pathology.
Organoids with human-relevant physiology and pathology are thought to
help overcoming these issues. Organoid cultures based on a specific
disease and even on a specific individual used in a high-throughput
manner are expected to develop into powerful tools for precision
therapy. Future screens may be performed using biobanks with the aim of
not only identifying new drugs but also revealing which patients may
benefit from treatment with certain drugs. In addition, focused tests of
potential drugs should identify new leads for the pharmaceutical
industry.Furthermore, organoidsmay be used in the future for toxicology
testing to complement, if not in part replace, animal testing.

could do for this kid and that he would die,” Rothoeft said in a
telephone news conference hosted byNature, which publishedthe

Thomas C. Südhof’s answer:The field of organoid research is still in
the beginning. Even for tissues like heart and liver, organoids are very
immature and only partly model the human organ. This is worse for brain.
Much fundamental biology, such as cell biology and biochemistry, is
needed to advance the field. This will take many years.

EllenFritsche答:类器官是融入了各类器官特异性细胞类型、组织形态和效劳的集体模型。但类器官仅为有限度的模仿,困扰那项手艺使用的多少个最重要限制是它的体积。当类器官体量扩充时,缺氧和不够可溶性因子所致的团组织坏死是索要消除的难点。解决这么些主题材料的叁个或然方案是激利肠府管生成路子,
进而使类器官血管化。那早已在hiPSC衍生的肝脏类器官上得逞促成。类器官领域的另一个挑衅在于二个安然无事的机体中所自然存在的器官“对话”。类器官钻探可满足生物工程的渴求,通过培育包括不一样等级次序hiPSC衍生类器官(展现多个器官系统的布局和功能)的五脏六腑芯片设备,用以在更近乎于体内的条件中筛选药物。别的,通过在类器官中加多免疫性细胞,还可参谋具备免疫性系统的团队间“对话”。别的,在药理和毒艺术学琢磨中,物质的肝脏代谢至关心珍惜要,那可通过以器官芯片的样式饱含肝脏代谢来完结。

Ellen Fritsche’s answer:Organoids are organ models recapitulating an
assortment of organ-specific cell types, tissue morphogenesis and
functions. Yet, there are limitations in their mimicry. One important
limitation plaguing the application of this technologyis their size.
When the organoids’ volume increases, the issue of tissue necrosis
caused by the lack of diffusion of oxygen and soluble factors needs to
be addressed. One solution for this problemmight be the activation
ofangiogenic pathways that will lead to vascularisedorganoids.This was
already succeeded with hiPSC-derived liver organoids. One more challenge
of the organoid field lies in organ crosstalk, which is naturally
present in an intact organism. Here, organoid research meets
bioengineering by producing organ-on-a-chip devices containing different
types of hiPSC-derived organoids representing the structure and function
of multiple organ systems for screening the effects of drugs in more in
vivo-like settings. The crosstalk of tissues with the immune system can
be modelled by adding immune cells to the organoids. For pharmacological
and toxicological applications, liver metabolism of compounds is
crucial. Including such metabolism via an organ-on-a-chip approach can
solve this issue.

Ellen Fritsche’s answer:Current trends for organoid research include
generation of organoid banks and platforms for high-throughput screening
approaches, generation of additional disease models, and set up of
organ-on-a-chip and microfluidics devices for whole organism modeling.
Here, especially medium constrictions have to be solved. For
microfluidics a common medium for all organoids on the chip is needed.
Moreover, depending on the organ system, physiologically relevant
high-throughput readouts from organoids need to be developed. On the
clinical side, research on personalized medicine using organoids derived
from patient-specific hiPSC is warranted for optimal individual
treatment regimes. In the toxicology field, organoids as substrates for
toxicity testing replacing animals is currently exploited.

Südhof答:作者的展望是在接下去的5年内好的实验室将学会怎么促进类器官的老到,并明显该办法的受制。我认为,固然类器官为干细胞钻探提供了宏伟的机会,如力促新意识和疗法的面世;但那将开支10年或越来越长的时光来发展。到那时候,也独有到那时候,走向应用才具真正变为或许。在那在此以前,大批量初创公司将会烧掉数以亿计的花费,他们中的少部分将会走向成功,并找到扩大营业收入的新路径。

Thomas C. Südhof’s answer:My prediction is that in 5 years, good
science labs will have learned how to mature organoids and the
limitations of the approach will have been defined. I think organoids
are a tremendous opportunity in stem cell approaches that will enable
novel discoveries and therapies, but that this will take at least 10
years to develop. Then and only then will it be possible to rationally
move towards applications. Until then, lots of start-ups will have spent
hundreds of millions of dollars, and a few of them will have been
successful in generating some future avenue of revenue.

to severe torture. It’s incredibly painful, and it can take up to 3 to 4

because her condition also affects mucous membranes. She often uses a

The skin therapy described in theNaturepaper wouldn’t cure her — in
fact, it targets a different genetic defect that causes the same
condition. But a similar approach could reduce the agony of daily
living. And Kopelan says medical interest in this disease is now growing
rapidly.

《自然》描述的皮层疗法不恐怕真正治愈她——事实上,它针对的是一种导致同样意况的两样的遗传弊端。不过类似的办法能够削减每日生活上的悲苦。Kopelan说,这种病如今正高速引起理学界的志趣。
