Preparation of Single-cell Suspensions for Cytofluorimetric Analysis from Different Mouse Skin Regions

Area of Science:

• Immunology
• Dermatology
• Cell Biology

Background:

• The skin acts as a critical barrier organ, constantly interacting with the external environment and housing diverse immune cells.
• Understanding skin-resident immune cells is vital for studying both homeostatic conditions and inflammatory responses to microbial challenges.
• Current methods for isolating skin cells for analysis can be limiting.

Purpose of the Study:

• To develop and validate an efficient protocol for obtaining single-cell suspensions from mouse skin.
• To ensure the protocol maintains high cell viability and preserves surface antigen expression for accurate analysis.
• To demonstrate the protocol's applicability across various anatomical locations of the mouse skin.

Main Methods:

• A novel enzymatic digestion method was employed for processing mouse skin samples.
• The protocol was optimized to rapidly yield single-cell suspensions from skin tissues.
• Skin samples were collected from multiple anatomical sites including ear, trunk, tail, and footpad.

Main Results:

• The developed methodology efficiently dissociates mouse skin into single-cell suspensions.
• The protocol successfully maintained high cell viability post-digestion.
• Surface antigen expression on immune cells remained intact, suitable for flow cytometry.
• The method proved effective for skin samples from diverse anatomical locations.

Conclusions:

• This protocol provides an efficient and reliable means to obtain viable single-cell suspensions from mouse skin.
• The methodology is valuable for studying skin-resident immune cell populations and their functions in various conditions.
• The technique supports detailed immunological investigations of the skin using flow cytometry.
