Generating an Excisional Skin Wound in a Mouse Model via Punch Biopsy

Abstract

Source: Anderson, L. S. et al., A Mouse Model to Assess Innate Immune Response to Staphylococcus aureus Infection. J. Vis. Exp. (2019)

This video demonstrates a punch biopsy procedure to create a precise wound in a mouse model. The excision exposes the subcutaneous layer of the skin, providing a suitable site for studying immune responses to localized pathogen infection.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.

1. Mouse Source and Housing

1. Derive Lysozyme M- enhanced green fluorescent protein (LysM-eGFP) mice on a C57BL/6J genetic background as described previously. Derive LysM-EGFP× myeloid differentiation primary response 88 (MyD88)-/- mice by crossing LysM-EGFP mice with MyD88-/- mice on a C57BL/6J background.
2. House mice in a vivarium. For these studies, animals were housed at the University of California, Davis in groups prior to surgery and singly housed fol....
