Nat Cell Biol:利用人工合成水凝胶投递细胞以修复肠道损伤

2017-10-27 佚名 中国生物技术网

研究人员将人工合成聚合材料的水凝胶与类器官的复杂肠组织(由人类多能干细胞形成)结合在一起,开发出控制这些组织生长,以及利用它们治疗消化系统损伤的新技术。消化系统损伤通常由炎性肠道疾病(IBD)引起,这一技术使他们向着成功又迈出重要一步。

研究人员将人工合成聚合材料的水凝胶与类器官的复杂肠组织(由人类多能干细胞形成)结合在一起,开发出控制这些组织生长,以及利用它们治疗消化系统损伤的新技术。消化系统损伤通常由炎性肠道疾病(IBD)引起,这一技术使他们向着成功又迈出重要一步。

美国乔治亚理工学院和密歇根大学的研究人员于近日在《Nature Cell Biology》上发表了这项研究。

研究人员利用合成的水凝胶构建了一个称谓基质的3D生长环境,它能够为类器官的生长提供最优的物理和生化支持。在过去,创造这种生长环境的方法是,使用来源于肿瘤细胞系的天然基质,该方法由密歇根大学内科医学副教授Jason Spence发明。在临床应用动物产品面临着巨大的挑战,因为这有可能导致人畜共患传染。

研究人员Asma Nusrat和密歇根大学医学院实验病理学教授Aldred Scott Warthin指出:“使用来源于小鼠肿瘤的基质将限制这些类器官技术未来在人类身上的应用,而这项工作为尤其适用于临床应用的研究打开了大门。”

除了能够使类器官在组织培养孵化器中的人工水凝胶中生长之外,该研究团队还声称,这种水凝胶可以像胶水一样,当它被植入到小鼠受伤的肠道中时,能够固定住类器官并促进伤口愈合。这项技术的成功为修复人类肠道损伤提供了新的疗法,甚至还有可能修复其他器官。

乔治亚理工学院机械工程学院的Andrés J. García教授说:“williamhill asia 发现,水凝胶基质可以帮助人类肠道类器官(HIO)移植到肠道组织上,HIO能分化成肠道组织并加速伤口愈合。这项工作对使用来源于干细胞的人类肠道类器官的疗法进行了概念验证。”


植入到动物体内之后,在水凝胶基质中形成的人类肠道类器官(HIO)分化成为成熟的肠组织,并在移植到动物体内后呈现特殊的人类肠细胞类型,如肠内分泌细胞(CHGA,红色)。

因为这种水凝胶基于明确的合成材料,它们具有在未来应用于人体治疗的优势。

密歇根大学博士后研究人员Miguel Quirós说:“这种人工生物合成的水凝胶的特性十分明确,因此在未来使用HIO的治疗中,它非常适用于人类患者。” Nusrat补充说:“在这项工作中,williamhill asia 证实,水凝胶可以促使HIO植入到受伤的肠道组织中,这表明该技术对于治疗因炎症肠道疾病而引起的肠道损伤非常有意义。”

由乔治亚理工学院开发了这种合成基质可以被很容易地修改,满足被培养细胞的需求。比如,该学院的研究生Ricardo Cruz-Acuna首先对多种组合进行了实验,最后才发现,由96%的水和一种特殊细胞粘附肽组成的凝胶对于HIO是最理想的。

Quirós和Cruz-Acuna利用一个小型结肠镜,将该凝胶和类器官投递到免疫缺陷小鼠受伤肠道的伤口处。被植入的细胞打上了标记,所以之后可以对其进行检测。四周之后,这些HIO完全移植到了受伤的区域,形成了类似正常组织的三维结构。而人工合成的凝胶消失了,被细胞自己生成的天然细胞外基质所替代。

García说:“由于williamhill asia 的水凝胶系统很容易修改,williamhill asia 可以修改其他的参数来生成支持多种细胞或类器官的机械和生物特性。对于不同应用的其他细胞来说,这些特性可能是不同的。”

接下来的工作中,研究人员将在免疫系统正常和不正常的动物模型中对他们的水凝胶基质进行测试。他们还需要优化包含HIO的水凝胶基质的给药方法,以替代在研究中使用的费时费力的技术。García, Nusrat和Spence认为,在人类试验开展之前,大规模动物试验是必要的。

除了肠道治疗外,研究人员还在研究利用这种水凝胶将类器官投递到受损的肾脏和肺脏中。

Int J Mol Sci:双组分水凝胶体系可促进外周神经的再生

对于下一代神经导管(NGC),需要新的生物材料和功能化概念来满足周围神经再生(PNR)的临床需求。作为具有生物活性基序的生物聚合物,凝胶肽则有希望满足这一需求,可与含酸酐的低聚物组合,建立了双组分水凝胶体系(cGEL)。首先,通过连续计量和模板方法制造空心cGEL管。导管的特征在于其机械强度,体外和体内降解和生物相容性。然后,将cGEL重新配制成用于建立的NGC的可注射剪切稀释填料,这里是由酪氨酸

糖尿病患者经常面临皮肤创面,尤其是足部创面难以愈合并最终形成糖尿病溃疡的风险,这是最常见也是最严重的糖尿病并发症之一。根据2015年WHO最新统计报告显示,中国糖尿病患者数量已突破1亿人,皮肤软组织缺损的病例亦是逐年递增,而如何让创面能够快速愈合并恢复正常成为临床上的棘手问题。其中,缺损区域周边的血管病变及新生血管减少是导致缺损难愈合的最重要的局部原因之一。随着对于糖尿病患者血管病变机理研究的深入

Small:智能水凝胶薄膜,一种恶性肿瘤血液检测的新方法

生物界面的设计在疾病诊断、生物医药、组织工程等领域都有十分重要的意义。传统的生物界面设计或着眼于表面化学的调控,或关注于表面拓扑结构的构筑。若将两者相结合则可以显着提高生物界面的性能,比如在纳米结构基底上修饰响应性分子能极大提高循环肿瘤细胞的捕获和释放效率。然而,这样的生物界面往往需要先构筑表面微纳米结构,再进行表面化学修饰;对外界响应主要由化学修饰实现。如何实现表面化学和结构的同时调控成为一个难

颅骨缺损是最常见和多样性的人类先天性异常之一,严重影响患者的生活质量,特别是创伤、肿瘤切除和血管损伤等造成的大面积的颅骨缺损。目前,颅骨损伤采用的最常见的治疗手段为自体骨和同种异体骨移植。然而,自体骨移植往往面临着形状匹配和来源有限的难题,同种异体骨移植容易引起免疫排斥反应。基于此,很多材料例如生物活性陶瓷、钛网、合成高分子或者它们的复合材料被尝试用于颅骨缺损修复,虽然一定程度上解决了自体和异体骨

Bone Res:仿生双相CAN-PAC水凝胶可用于软骨缺损修复

基于仿生支架的软骨组织工程已成为修复软骨缺陷的一个重要方法。在本研究中,研究人员通过热反应快速交联方法,利用两层之间的密度差制备了用于软骨缺损(OCD)再生的双相CAN-PAC水凝胶。上水凝胶通过CSMA和NIPAm交联,下水凝胶由PECDA,AAm和PEGDA组成。两层之间的界面首先通过葡萄糖酸钙和藻酸盐的物理交联连接,然后在其它组分中进行碳-碳双键的化学交联。上下水凝胶的孔径分别为〜187.4
