Abstract
Retinal degeneration (RD) is a leading cause of blindness worldwide and includes conditions such as retinitis pigmentosa (RP), age-related macular degeneration (AMD), and Stargardt's disease (STGD). These diseases result in the permanent loss of vision due to the progressive and irreversible degeneration of retinal cells, including photoreceptors (PR) and the retinal pigment epithelium (RPE). The adult human retina has limited abilities to regenerate and repair itself, making it challenging to achieve complete self-replenishment and functional repair of retinal cells. Currently, there is no effective clinical treatment for RD. Stem cell therapy, which involves transplanting exogenous stem cells such as retinal progenitor cells (RPCs), embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), and mesenchymal stem cells (MSCs), or activating endogenous stem cells like Müller Glia (MG) cells, holds great promise for regenerating and repairing retinal cells in the treatment of RD. Several preclinical and clinical studies have shown the potential of stem cell-based therapies for RD. However, the clinical translation of these therapies for the reconstruction of substantial vision still faces significant challenges. This review provides a comprehensive overview of stem/progenitor cell-based therapy strategies for RD, summarizes recent advances in preclinical studies and clinical trials, and highlights the major challenges in using stem/progenitor cell-based therapies for RD.
期刊介绍：
The purpose of Stem Cell Reviews and Reports is to cover contemporary and emerging areas in stem cell research and regenerative medicine. The journal will consider for publication:
i) solicited or unsolicited reviews of topical areas of stem cell biology that highlight, critique and synthesize recent important findings in the field.
ii) full length and short reports presenting original experimental work.
iii) translational stem cell studies describing results of clinical trials using stem cells as therapeutics.
iv) papers focused on diseases of stem cells.
v) hypothesis and commentary articles as opinion-based pieces in which authors can propose a new theory, interpretation of a controversial area in stem cell biology, or a stem cell biology question or paradigm. These articles contain more speculation than reviews, but they should be based on solid rationale.
vi) protocols as peer-reviewed procedures that provide step-by-step descriptions, outlined in sufficient detail, so that both experts and novices can apply them to their own research.
vii) letters to the editor and correspondence.
In order to facilitate this exchange of scientific information and exciting novel ideas, the journal has created five thematic sections, focusing on:
i) the role of adult stem cells in tissue regeneration;
ii) progress in research on induced pluripotent stem cells, embryonic stem cells and mechanism governing embryogenesis and tissue development;
iii) the role of microenvironment and extracellular microvesicles in directing the fate of stem cells;
iv) mechanisms of stem cell trafficking, stem cell mobilization and homing with special emphasis on hematopoiesis;
v) the role of stem cells in aging processes and cancerogenesis.
