Why use neonatal Sprague-Dawley rats?
Neonatal Sprague-Dawley rats are commonly used due to their availability and the quality of retinal cells obtained.
What is the significance of isolating Müller cells?
Isolating Müller cells allows researchers to study their role in retinal health and disease mechanisms.
How is cell purity assessed?
Cell purity is assessed using immunofluorescence and flow cytometry to confirm the expression of specific markers.
What applications do isolated Müller cells have?
Isolated Müller cells can be used to study retinal diseases, drug effects, and cellular responses to injury.
What are the key steps in the isolation protocol?
Key steps include enucleation, dissection, trypsin digestion, and centrifugation to purify the cells.
