Analysis of P2X7-Induced Neuronal Branching

Area of Science:

• Neuroscience
• Cell Biology
• Developmental Biology

Background:

• Primary neuronal cultures are essential for studying molecular and cellular events in neuroscience.
• These cultures allow for controlled investigation of ion channels, receptors, and transporters.
• Mouse models offer genetic diversity for studying neuronal development.

Purpose of the Study:

• To present a detailed protocol for isolating and culturing primary hippocampal cells from embryonic mice.
• To enable the study of neuronal development, specifically dendritic and axonal morphology.
• To provide a method for visualizing and analyzing neuronal structure in detail.

Main Methods:

• Isolation and culturing of primary hippocampal cells from embryonic mouse tissue (E17.5-18.5).
• Culturing on poly-L-lysine/laminin coated coverslips with controlled astroglia proliferation.
• Neuron transfection for fluorescent protein filling, followed by Sholl analysis using Neurolucida software for dendritic branching assessment.

Main Results:

• Successful isolation and long-term culture of primary hippocampal neurons.
• Demonstration of a transfection protocol for comprehensive neuronal imaging.
• Quantification of dendritic branching patterns using Sholl analysis.

Conclusions:

• The presented protocol provides a robust method for studying neuronal development and morphology in vitro.
• This technique is valuable for investigating the roles of specific genes or treatments on neuronal structure.
• The method supports detailed morphological analysis crucial for understanding neuronal function.
