The cornea is the outermost layer of eye and plays an essential role in our visual system. Limbal epithelial stem cells (LESCs), which are localized to a highly regulated limbal niche, master conductors corneal regeneration. Damage LESCs their niche may result cell deficiency (LSCD), disease confused ophthalmologists so many years can lead conjunctivalization, neovascularization, even blindness. How restore function hot topic for ocular scientists clinicians around world. This review introduced microenvironment, outlined various techniques isolating culturing used LSCD research, presented common diseases that cause LSCD, provided comprehensive overview both diagnosis multiple treatments from basic research clinical therapies, especially emerging therapies based on sources. In addition, we also innovatively concluded latest strategies recent years, including exogenous drugs, tissue engineering, nanotechnology, exosome gene therapy, as well ongoing trials treating five years. Finally, highlighted challenges bench bedside discussed cutting-edge areas therapeutic research. We hope this could pave way future translation crucial step field health.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common complication that affects an increasing number of cancer survivors. However, the current treatment options for CIPN are limited. Paclitaxel (PTX) widely used chemotherapeutic drug induces senescence in cells. While previous studies have demonstrated Sonic hedgehog (Shh) can counteract cellular dysfunction during aging, its role remains unknown. Herein, aim this study was to investigate whether Shh activation could inhibits neuronal/glial and alleviates CIPN. We treated ND7/23 neuronal cells RSC96 Schwann with two selective activators (purmorphamine [PUR] smoothened agonist [SAG]) presence PTX. Additionally, we utilized mouse model induced by PTX injection. To assess senescence, performed senescence-associated β-galactosidase (SA-β-gal) assay, measured reactive oxygen species (ROS) levels, examined expression P16, P21, γH2AX. understand underlying mechanisms, conducted ubiquitin assays, LC-MS/MS, H&E staining, assessed protein through Western blotting immunofluorescence staining. In vitro, observed significantly alleviated senescence-related decline multiple functions included SA-β-gal activity, P16 cell viability, ROS accumulation DRG sensory neurons after exposure. Furthermore, our vivo experiments reduced axonal degeneration, demyelination, improved nerve conduction. Mechanistically, discovered level SP1, which ubiquitinated E3 ligase TRIM25 at lysine 694 (K694), leading increased CXCL13 expression, found inhibited PTX-induced TRIM25-SP1-CXCL13 axis. These findings provide evidence cells, suggesting be potential therapeutic target

Abstract Spinal cord injury, traumatic brain and neurosurgery procedures usually lead to neural tissue damage. Self‐assembled peptide (SAP) hydrogels, a type of innovative hierarchical nanofiber‐forming sequences serving as hydrogelators, have emerged promising solution for repairing defects promoting regeneration. SAPs possess numerous features, such adaptable morphologies, biocompatibility, injectability, tunable mechanical stability, mimicking the native extracellular matrix. This review explores capacity cell regeneration examines critical aspects in neuroregeneration, including their biochemical composition, topology, behavior, conductivity, degradability. Additionally, it delves into latest strategies involving central or peripheral engineering. Finally, prospects SAP hydrogel design development realm neuroregeneration are discussed.
