studies on the survival of histocompatibility-y antigen ( h-y ) -incompatible and skin-specific antigen ( skn ) -incompatible skin grafts in mice , as well as those concerned with the survival of cultured parathyroid allografts in rats , indicate that grafts provoke a strong immune response only if they include donor macrophages ( or langerhans cells ) or if major histocompatibility complex-compatible macrophages are available to react with cells bearing the foreign antigens .
