Abstract
National Eye Institute recently issued a new Strategic Plan outlining priority research areas for the next 5 years. Starting cell source for deriving stem cell lines is as an area with gaps and opportunities for making progress in regenerative medicine, a key area of emphasis within the NEI Strategic Plan. There is a critical need to understand how starting cell source affects the cell therapy product and what specific manufacturing capabilities and quality control standards are required for autologous vs allogeneic stem cell sources. With the goal of addressing some of these questions, in discussion with the community-at-large, NEI hosted a Town Hall at the Association for Research in Vision and Ophthalmology annual meeting in May 2022. This session leveraged recent clinical advances in autologous and allogeneic RPE replacement strategies to develop guidance for upcoming cell therapies for photoreceptors, retinal ganglion cells, and other ocular cell types. Our focus on stem cell-based therapies for RPE underscores the relatively advanced stage of RPE cell therapies to patients with several ongoing clinical trials. Thus, this workshop encouraged lessons learned from the RPE field to help accelerate progress in developing stem cell-based therapies in other ocular tissues. This report provides a synthesis of the key points discussed at the Town Hall and highlights needs and opportunities in ocular regenerative medicine.

[PMID: 37152866 PMCID: PMC10162109 DOI: 10.2147/jir.s404983] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 04/14/2023] [Indexed: 05/09/2023] Open
Abstract
Burns are a seriously underestimated form of trauma that not only damage the skin system but also cause various complications, such as acute kidney injury (AKI). Recent clinical studies have shown that the proportion of chronic kidney diseases (CKD) in burn patients after discharge is significantly higher than that in the general population, but the mechanism behind this is controversial. The traditional view is that CKD is associated with hypoperfusion, AKI, sepsis, and drugs administered in the early stages of burns. However, recent studies have shown that burns can cause long-term immune dysfunction, which is a high-risk factor for CKD. This suggests that burns affect the kidneys more than previously recognized. In other words, severe burns are not only an acute injury but also a chronic disease. Neglecting to study long-term kidney function in burn patients also results in a lack of preventive and therapeutic methods being developed. Furthermore, stem cells and their exosomes have shown excellent comprehensive therapeutic properties in the prevention and treatment of CKD, making them increasingly the focus of research attention. Their engineering strategy further improved the therapeutic performance. This review will focus on the research advances in burns on the development of CKD, illustrating the possible mechanism of burn-induced CKD and introducing potential biological treatment options and their engineering strategies.

2021): Key issues for future research and development. Cell Prolif 2022; 55:e13301. [PMID: 35933704 PMCID: PMC9357356 DOI: 10.1111/cpr.13301] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 06/14/2022] [Indexed: 12/12/2022] Open
Abstract
Human pluripotent stem cells (hPSC) have the capability to deliver novel cell‐based medicines that could transform medical treatments for a wide range of diseases including age‐related degenerative disorders and traumatic injury. In spite of significant investment in this area, due to the novel nature of these hPSC‐based medicines, there are challenges in almost all aspects of their manufacturing including bioprocessing, characterization and delivery. The Chinese Academy of Sciences and the Chinese Society for Stem Cell Research have collaborated to create a new discussion forum called PSConf 2021 (Pluripotent Stem Cell Conference 2021), intended to promote exchanges in communication on cutting‐edge developments and international coordination in hPSC manufacturing. The PSConf 2021 addressed crucial topics in stem cell‐based manufacturing, including stem cell differentiation, culture scale‐up, product formulation and release. This report summarizes the proceedings and conclusions from the discussion sessions, and it is accompanied by publication of individual papers from the speakers at the PSConf 2021.
