Müller Glial Cells is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes. [@reichenbach2014]
Overview
Müller cells are the principal radial glial cells of the retina, extending from the outer limiting membrane to the inner limiting membrane. They provide structural support, metabolic maintenance, and regulate the extracellular environment for retinal neurons. Müller cells are essential for retinal homeostasis and have emerged as important players in retinal degeneration and potential regenerative therapies for neurodegenerative diseases affecting the eye.
