Skin explant culture as a model for cutaneous graft-versus-host disease in humans

Bone Marrow Transplant. 1988 Jul;3(4):323-9.


An in vitro skin explant model for graft-versus-host disease (GVHD) in humans has been used to study the role of effector T cells in the histological pathogenesis of GVHD. In 11 of 12 experiments clear GVHD changes of grades II-IV were induced in HLA-mismatched skin explants cultured with allogeneic T cells sensitized by in vitro mixed lymphocyte culture. The role of effector T cells was investigated by comparing results before and after removal of CD3 positive cells, and CD4 positive and CD8 positive T cell-subsets by antibody and complement cytolysis from responder populations. Only total removal of CD3 positive T cells prevented histopathological lesions of GVHD in the skin biopsy specimens. The results also demonstrated that the CD4 positive population caused the greatest degree of GVHD in vitro in skin biopsy specimens and direct infiltration into skin by cells is not required for changes to become evident. These results confirm the early results on animal models and demonstrate the use of the skin explant model as a tool for studying the biology of GVHD in humans.
