3D Culture Reverses Limbal Niche Cell Replicative Aging via FOSL1 Upregulation

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
3D culture reverses LNC replicative aging via FOSL1 upregulation, enhancing mitochondrial function and alleviating oxidative stress. ABSTRACT Limbal niche cells (LNCs) serve as essential regulators of limbal microenvironmental homeostasis and corneal epithelial wound repair, representing a promising therapeutic resource for limbal stem cell deficiency (

Ectopic expression of the erythrocyte band 3 anion exchange protein, using a new avian retrovirus vector.

open access: yes, 1990
Udgivelsesdato: 1990-DecA retrovirus vector was constructed from the genome of avian erythroblastosis virus ES4. The v-erbA sequences of avian erythroblastosis virus were replaced by those coding for neomycin phosphotransferase, creating a gag-neo fusion

Research on Alkaline Anion Exchange Membrane Fuel Cells

open access: yes, 2011
In this work, we report on the preparation of a novel type of PTFE based composite anion exchange membrane for alkaline fuel cells. The membranes were synthesized by in-situ polymerization of N-vinylformamide monomer in the PTFE matrix followed by ...
