中文摘要
视网膜色素上皮细胞(RPE)在长期存活过程中维持组织稳态,
有证据表明细胞重新产生。由于眼睛的持续生长和衰老,细胞密度降低,
RPE细胞通常经历肥大。 中央RPE的变性引起进行性慢性视网膜色素变性。
老年性黄斑变性(AMD)是老年人不可逆视力丧失的主要原因
人口除了一些保护策略外,目前还没有有效的治疗AMD的方法。最近的研究
揭示了大量的细胞异质性可能是存在于整个RPE中的特征。重要的是,某些
这种异质RPE细胞群的亚群可能含有有助于再生的不同性质,

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.
