中文摘要
主要的视网膜色素上皮细胞(RPE)通过长期的细胞存活来维持组织的动态平衡,而且几乎没有什么。
有新的细胞产生的证据。由于眼睛的持续生长速度和衰老,细胞密度和年龄都在下降。
RPE细胞一般会发生肥大。中央RPE细胞的退变是导致进行性和慢性疾病的原因。
老年性黄斑变性疾病(AMD)是导致老年人不可逆的视力丧失的主要原因。
人口。除了一些有效的保护性治疗策略外,目前还没有有效的治疗AMD的方法。最近的研究显示。
他透露,细胞的实质性异质性可能是贯穿整个RPE的一个重要特征。更重要的是,它具有一定的可操作性。
这种异质的RPE细胞群体的子集可能还包含一些独特的属性,有助于细胞再生。
由于拥有自我更新的内在能力,我们和其他人已经确定了信号通路是人类发展的关键因素。
RPE是指增长和差异化,特别是河马和河马的路径。在这里,我们要提出一些建议,以进一步探索如何做到这一点。
对这类信号通路的遗传调控可以更好地刺激最成熟的哺乳动物视网膜色素上皮细胞的再生修复能力。
并努力识别具有再生能力的RPE亚群。我们的研究将为我们提供对其潜力的更深入的洞察。
新奇的金融监管机构正在刺激一种内在的、再生的金融反应。在最成熟的金融RPE中。通过确定候选的金融目标。

英文摘要
The retinal pigment epithelium (RPE) maintains tissue homeostasis through long-term survival, with little
evidence of de novo cell production. Due to continued growth of the eye and aging, cell density decreases and
RPE cells generally undergo hypertrophy. Degeneration of the central RPE causes the progressive chronic
disease age-related macular degeneration (AMD), the leading cause of irreversible vision loss in the elderly
population. Besides some protective strategies, no effective cure for AMD is currently available. Recent studies
revealed that substantial cell heterogeneity may be a feature that exists throughout the RPE. Importantly, certain
subsets of this heterogeneous RPE cell population may contain distinct properties contributing to regeneration,
with an intrinsic capacity for self-renewal. We and others identified signaling pathways critical for developmental
RPE growth and differentiation, specifically the Hippo and Wnt pathways. Here we propose to explore how
genetic modulation of such signaling pathways can stimulate regenerative repair in the mature mammalian RPE
and to identify RPE subpopulations with regenerative potential. Our studies will provide insight into potential
novel regulators stimulating an intrinsic, regenerative response in the mature RPE. Identifying candidate targets
for clinical therapy is a critical step forward for treatment of RPE-related diseases with currently very limited
therapeutic potential, such as atrophic AMD.
