Uncovered skin grafts in mice.

Area of Science:

• Immunology
• Surgical Techniques

Background:

• Assessing immune rejection in mice often requires reliable grafting methods.
• Existing techniques may obscure graft visibility or lead to inconsistent results.

Purpose of the Study:

• To describe a new ear skin grafting technique in mice.
• To evaluate its utility in observing graft survival and assessing immune rejection.

Main Methods:

• Suturing ear skin onto the lateral thoracic area of recipient mice.
• Observing graft visibility from transplantation to complete rejection.
• Monitoring survival times in established donor-recipient combinations.

Main Results:

• The graft remained visible throughout the observation period without hindering the mice.
• Consistent mean survival times were achieved over a year.
• Technical failures were easily identifiable.
• The technique accurately assessed accelerated rejection responses (4-8 days post-grafting).

Conclusions:

• This ear skin grafting technique provides a reliable and visible model for studying immune rejection in mice.
• It facilitates accurate assessment of accelerated rejection responses mediated by effector cells.
