What is electroporation?
Electroporation is a technique that uses electrical current to create temporary pores in cell membranes, allowing substances to enter the cells.
Why is indium tin oxide used?
Indium tin oxide is conductive and transparent, making it suitable for electroporation while allowing observation of the cells.
What are gap junctions?
Gap junctions are small channels that connect neighboring cells, facilitating the passage of small molecules and ions.
What is the significance of studying intercellular communication?
Understanding intercellular communication is crucial for insights into various cellular functions and processes, including development and disease.
How does electroporation affect cell viability?
Electroporation creates transient pores that close quickly, typically without damaging the cells if performed correctly.
Can this method be applied to other cell types?
Yes, electroporation can potentially be applied to various cell types, depending on the specific experimental conditions.
