Cell:畸胎瘤不仅是瘤,还有望应用于多谱系发育建模

2020-11-14 张佳兴 生物探索

发育生物学的研究常常受到模式动物的限制,近些年来,研究人员利用人类多能干细胞(hPSC)开发出了一系列的三维类器官模型,使研究人员能够在3D环境中模拟人类特有的发育。

发育生物学的研究常常受到模式动物的限制,近些年来,研究人员利用人类多能干细胞(hPSC)开发出了一系列的三维类器官模型,使研究人员能够在3D环境中模拟人类特有的发育。然而,这些器官模型仍局限于单一或少数发育谱系,且其规模受到欠发达的血管系统的限制。研究人员一直试图寻求更好的模型进行研究工作。

畸胎瘤是一种生殖细胞肿瘤,它包括所有三个胚层的多谱系分化,具有足够的血管和复杂的组织区域,并且相对容易诱导。因此,畸胎瘤具有作为发育模型使用的潜力。

《Cell》杂志在线发表了美国加州大学圣地亚哥分校Prashant Mali和张鹍团队名为“Definingthe Teratoma as a Model for Multi-lineage Human Development”的合作研究。在此研究中,他们探讨了畸胎瘤作为人多谱系发育模型的潜力。

研究人员将hPSC注射到免疫缺陷小鼠体内,诱导畸胎瘤形成后使用单细胞测序技术对其中包含的细胞类型进行分析,最终得到了23个细胞类型。通过将每个畸胎瘤细胞类型的表达与小鼠器官发生细胞图谱中的细胞类型表达相关联,研究人员验证了畸胎瘤作为早期胚胎发育模型的潜能。

畸胎瘤细胞类型

随后,研究人员进一步评估了畸胎瘤的异质性,特别是不同干细胞系产生的畸胎瘤之间的异质性。结果显示,不同来源的畸胎瘤都包含了主要的细胞类群,但在细胞比例等方面存在差异。相反的是,畸胎瘤细胞类型与人类胎儿细胞类型的转录相似,这表明了其作为建模人类早期胚胎发育模型的效用。

畸胎瘤异质性

为了建立畸胎瘤系统作为人类发育模型的实用价值,研究人员使用CRISPR-Cas9进行了单细胞基因敲除筛选。通过CRISPR KO筛选关键的发育调控因子,研究人员能够同时测定目的基因在人类特定模型中的多种功能。目前,其他人类发育模型目前还无法完成这一工作。

畸胎瘤遗传干扰

研究人员成功地开发了一个miRNA系统,能够将畸胎瘤设计成所需的谱系,并可以应用于发育生物学和人类疾病的研究以及组织工程。

总而言之,虽然此研究尚未验证所有的细胞类型,但畸胎瘤有希望开发为一个平台,用于建模多谱系发育,全组织功能基因筛选和组织工程等。

Science Advances :孙进团队对阿霉素进行改造,对于肿瘤治疗有更好的益处

大多数抗肿瘤药物缺乏与纳米载体的亲和力,导致药物载量低(通常少于10%),胶体稳定性差以及全身循环中药物过早泄漏。此外,如何实现肿瘤特异性药物释放也是纳米递送系统设计的一个挑战。

Cell Metabolism:中国科学家揭示,抗衰老新宠烟酰胺:能改善癌症免疫治疗效果

近年来,免疫检查点抑制剂在肿瘤免疫治疗方面取得了突破性进展。程序性死亡配体1 (PD-L1) 在多种癌症中高表达,并通过与其在T细胞表面的受体PD-1相互作用来调节免疫逃避,导致T细胞衰竭。

Sci Adv :陈学思院士团队开发免疫鸡尾酒疗法,肿瘤缩小率更高达97.3%

免疫检查点抑制剂是一种很有前景的癌症免疫疗法,但在许多肿瘤中,低应答率限制了其进一步应用。尽管科学家们已经开发出一些联合疗法来增强免疫检查点抑制剂的疗效,但在多种肿瘤模型中这些疗法仍未产生良好的肿瘤。

Nat Metab:细胞的“酸碱体质”可以调节肿瘤生长

癌细胞的生长和增殖增强伴随着细胞代谢的深刻变化。这些代谢变化在生理条件下也是常见的,包括葡萄糖酵解增加,伴随着细胞pH值(pHc)的升高。然而,至今为止,这些变化如何帮助增强细胞的生长和增殖还不清楚。

Elife :运动是如何通过免疫系统抑制肿瘤生长的?

运动能够促进人体的新陈代谢,增强心肺功能,加强肌肉、韧带和骨骼等,具有全身性的广泛益处。先前的研究表明,除了可以锻炼身体外,运动还具有减少恶性肿瘤的进展,改善多种癌症预后的功能。

Nature:除了抗PD-1,还可以通过磷酸酶募集来抑制免疫受体

拮抗细胞外受体-配体相互作用的抗体可以抑制细胞表面受体的信号传递,目前广泛应用于包括肿瘤在内的多种疾病的治疗。比如,共受体(如PD-1和CTLA-4)对T细胞信号的调节一直是肿瘤免疫治疗的关键。
