Isolation and Patch-Clamp of Primary Adipocytes.

Area of Science:

• Physiology
• Cell Biology
• Biophysics

Background:

• Ion channels are crucial for adipocyte signaling.
• Understanding ion channel function in adipocytes requires specific experimental techniques.
• Current methods may not fully capture ion channel activity in the native adipocyte environment.

Purpose of the Study:

• To describe robust methods for isolating primary mature adipocytes from human and mouse white adipose tissue.
• To outline procedures for culturing and differentiating preadipocytes from the stromal vascular fraction.
• To detail patch-clamp techniques for investigating ion channel function in adipocytes.

Main Methods:

• Isolation of primary mature adipocytes from subcutaneous and visceral white adipose tissue (mouse and human).
• Culture and differentiation of preadipocytes derived from the stromal vascular fraction.
• Application of patch-clamp electrophysiology, including whole-cell and perforated-patch configurations.

Main Results:

• Successful isolation and culture of functional adipocytes and preadipocytes.
• Demonstration of patch-clamp techniques applicable to these cell types.
• Establishment of a comprehensive protocol for studying adipocyte ion channels.

Conclusions:

• The described methods enable detailed investigation of ion channel activity in the native adipocyte environment.
• These techniques facilitate a deeper understanding of ion channels' role in adipocyte signaling.
• The protocol provides a valuable resource for researchers studying adipose tissue physiology and metabolism.
