Retinal dystrophies (RDs) lead to irreversible vision impairment with no radical treatment. Although photoreceptor cells (PRCs) differentiated from human induced pluripotent stem cells (iPSCs) are essential for the study of RDs as a scalable source, current differentiation methods for PRCs require multiple steps. To address these issues, we developed a method to generate PRCs from human iPSCs by introducing the transcription factors, CRX and NEUROD1. This approach enabled us to generate induced photoreceptor-like cells (iPRCs) expressing PRC markers. Single-cell RNA sequencing revealed the transcriptome of iPRCs in which the genes associated with phototransduction were expressed. Generated iPRCs exhibited their functional properties in calcium imaging. Furthermore, light-induced damage on iPRCs was inhibited by an antioxidant compound. This simple approach would facilitate the availability of materials for PRC-related research and provide a useful application for disease modeling and drug discovery.

Deciphering inter- and intracellular signaling pathways is pivotal for understanding the intricate communication networks that orchestrate life's dynamics. Communication models involving bottom-up construction of protocells are emerging but often lack specialized compartments sufficiently robust and hierarchically organized to perform spatiotemporally defined signaling. Here, the modular construction of communicating polymer-based protocells designed to mimic the transduction of information in retinal photoreceptors is presented.

Oxidative stress is pivotal in retinal disease progression, causing dysfunction in various retinal components. An effective antioxidant, such as probucol (PB), is vital to counteract oxidative stress and emerges as a potential candidate for treating retinal degeneration. However, the challenges associated with delivering lipophilic drugs such as PB to the posterior segment of the eye, specifically targeting photoreceptor cells, necessitate innovative solutions.

Article Synopsis
  • MicroRNAs, like MIR96, help brain cells develop and function, especially in the eyes, which is important for vision.
  • Researchers added a MIR96 mimic to special cells from human bone marrow to see how it helps these cells turn into eye cells.
  • The study found that after 24 and 48 hours, these cells showed signs of becoming photoreceptor cells, suggesting that using MIR96 might help treat eye diseases.

Retinal dystrophies are a common health problem worldwide that are currently incurable due to the inability of retinal cells to regenerate. Inherited retinal diseases (IRDs) are a diverse group of disorders characterized by progressive vision loss caused by photoreceptor cell dysfunction. The eye has always been an attractive organ for the development of novel therapies due to its independent access to the systemic pathway.

Article Synopsis
  • * Adipose-derived mesenchymal stem cells (ADMSCs) are promising for treating diabetes complications due to their abundance, easy collection, and the various beneficial substances they release that can aid in healing and regeneration.
  • * While preclinical studies have shown positive effects of ADMSC therapy in improving diabetes-related issues, there are still barriers to its application in human treatments, though several clinical trials are currently exploring their use, especially for diabetic foot ulcers.
