PNAS:干细胞治疗可缓解眼压降低青光眼风险

2016-07-28 佚名 生物谷

近日,来自美国爱荷华大学的研究人员发表一项最新研究进展,他们向青光眼小鼠模型的眼内输注利用干细胞分化得到的小梁网状细胞能够帮助解决流体堵塞问题重新恢复适当的液体流出,这样可以降低眼压从而降低青光眼患病风险。 研究人员将新生细胞注射到青光眼小鼠模型的眼内,发现新细胞的流入能够帮助小梁网状结构再生,该结构是眼部的一个排水管道能够帮助避免出现液体累积,如果液体在眼睛里累积会使眼压升高容易导致青

近日,来自美国爱荷华大学的研究人员发表一项最新研究进展,他们向青光眼小鼠模型的眼内输注利用干细胞分化得到的小梁网状细胞能够帮助解决流体堵塞问题重新恢复适当的液体流出,这样可以降低眼压从而降低青光眼患病风险。
 
研究人员将新生细胞注射到青光眼小鼠模型的眼内,发现新细胞的流入能够帮助小梁网状结构再生,该结构是眼部的一个排水管道能够帮助避免出现液体累积,如果液体在眼睛里累积会使眼压升高容易导致青光眼。这种疾病会损伤视神经,可能导致失明。
 
"我们认为用健康细胞替代损伤或缺失的小梁网状细胞能够重新恢复小梁网状结构的功能。"文章作者Kuehn在他们实验室的网站上这样写道。
 
相关研究结果发表在国际学术期刊PNAS上。
 
这种方法的一个潜在优势就是利用病人自身皮肤细胞获得诱导多能干细胞,这样就能避开使用胎儿干细胞存在的伦理问题,还会降低病人机体对移植细胞的排斥反应。
 
Kuehn等人利用一种基于人类小梁网状细胞培养条件开发的条件培养基成功诱导干细胞生长为类似小梁网状细胞。随后他们将获得的新生细胞注射到小鼠眼部,发现这还会导致内源性小梁网状细胞的增殖。换句话说,注射进去的新细胞不仅能够自身存活,还可以促进机体产生更多自身细胞,从而进一步提高了治疗效果。研究人员在移植9周后检测了小鼠的治疗效果,实验室小鼠一般存活两到三年,9周大约相当于人类的五到六年。
 
研究人员表示目前青光眼还无法治愈,只能通过控制病情防止失明。目前主要的治疗方法就是使用滴眼液,进行激光或者传统手术。他们认为这项研究已经带来了常见青光眼治疗(原发性开角型青光眼)的希望。

Science:英国科学家揭示神经干细胞重回静默状态的重要机制

近日,著名国际学术期刊Science刊登了英国弗朗西斯克里克研究所-米尔希尔实验室研究人员的一项最新研究进展,在这篇文章中他们发现了增殖状态下的神经干细胞如何重新回到静默状态,从而维持神经干细胞池的平衡。海马体是大脑中负责调节记忆和情绪的重要区域,其中的神经干细胞能够产生新的神经元,即使在成年阶段也具有这样的能力。形成多少个新的神经元以及何时形成新的神经元取决于神经干细胞池的静默和增殖之间的平衡。

Stem Cells:沉默microRNA促进间充质干细胞进行关节软骨损伤修复

最近来自意大利的科学家们在国际学术期刊Stem Cells上发表了一项最新研究进展,他们发现在人类间充质干细胞中沉默一种抗软骨形成的microRNA能够促进间充质干细胞向软骨细胞方向分化,为应用间充质干细胞进行体内软骨组织修复提供了新的可能。随着间充质干细胞在临床应用原来越为广泛,对借助组织工程技术利用人类间充质干细胞进行有效的关节软骨修复的需求越来越大。但是想要利用hMSC实现对软骨的修复,如何

Stem Cells:新研究在干细胞中找到“不老之泉”的奥秘

最近一项研究表明不老之泉的奥秘可能在于胚胎干细胞中一个叫Nanog的基因。“关于Nanog的研究帮助我们更好地理解衰老过程,最终知道如何逆转衰老。”文章作者Stelios T. Andreadis教授这样说道。为了对抗衰老,机体储备了一些具有器官再生能力的成体干细胞,这些干细胞位于机体的每个组织内,能够在需要的时候快速应答。但是随着人们年龄的增长,许多成体干细胞无法再很好地完成它们的工作,这就可能

深度解析免疫细胞和干细胞之间的作用机制 助力干细胞再生疗法的开发

我们可能会认为自己是静态的生物,但实际上我们机体的细胞处于持续的流动之中,机体皮肤和肠道的外层组织每隔几周都会被替换,红细胞在替换之前都会在机体中循环大约100天,而肝脏和脂肪细胞往往寿命较长,每一个肝脏细胞都可以生存超过1年时间,而脂肪细胞的平均寿命为10年,在我们一生过程中这些细胞会反复地替换更新,在个体正常的一生中有大约一半的心脏细胞都会被替换;当健康组织因受伤而缺失时,新生细胞就会去修

干细胞解冻“渐冻人”,2期临床顺利收官

“冰桶挑战”公益活动曾风靡全球,它呼吁着人们关注“渐冻人”(ALS,肌萎缩性侧索硬化)这一长期得不到有效治疗的罕见病患者群体。 值得庆幸的是,BrainStorm Cell Therapeutics公司近日宣布,其在研技术平台NurOwn治疗ALS的2期临床完美收官,达到主要终点,表现出了良好的安全性和耐受性,同时还显示有持续长达24周的明显临床受益。 肌萎缩性侧索硬化是一种致命的渐进
