Abstract
Skin transplantation in mice is an important procedure to evaluate immune responses generated against heterologous grafts, especially given its highly immunogenic nature. In fact, skin is one of the most challenging organs in terms of allograft retention. In this protocol, we provide a detailed procedure for skin grafting using the tail skin as donor organ that is grafted on the dorsal site of thoracic cage in a recipient mouse. We also provide protocols for the systematic analysis of lymphoid organ analysis in transplanted mice. Together these protocols may be valuable for evaluation of parameters that affect skin grafting, including genetic factors, immune cell activation as well as the analysis of compounds that may be useful in allowing graft tolerance.
Keywords: Skin transplantation (皮肤移植)Background
Transplantation of organs remains the only life-saving procedure for many end-stage organ failures. However, the success of organ transplantation is severely limited by first, the availability of a suitable donor with a matched Human Leucocyte Antigen (also known as HLA typing/organ matching), and second, the fact that even in cases of matched transplants, recipients have to be subjected to immunosuppressive therapy where multiple drugs are administered life-long, resulting in severe side effects (Lopez et al., 2006; Green, 2013; Rodriguez-Peralvarez et al., 2014). Therefore, a better understanding of the factors that allow graft acceptance, as well as the availability of sensitive protocols to assay immune cell activation are important. We have employed a mouse model for skin transplantation, where a biopsy from a tail skin is grafted onto the dorsum of a recipient mouse (Schmaler et al., 2014; Jayachandran et al., 2019). Such a procedure not only allows for relative ease of obtaining tail skin graft from a single donor for performing transplantation onto multiple recipients, but also aids in rapid assessment of the graft health status due to the presence of the characteristic hyperpigmented tail stripe (from melanin, a characteristic feature of healthy tail skin), that rapidly fades upon rejection, thereby allowing a relatively straightforward evaluation of its tolerance and/or rejection following transplantation.
