Abstract

Chronic proliferative dermatitis is a spontaneous mutation in C57BL/Ka mice (cpdm/cpdm) and is characterized by epithelial hyperproliferation, infiltration by eosinophils and macrophages, and vascular dilatation. To elucidate whether these pathologic features are the result of a local (skin) process or a consequence of a systemic disorder, transplantations were performed of full-thickness grafts of affected skin from cpdm/cpdm mice and normal skin from control (C57BL/Ka) mice on the back of cpdm/cpdm, C57BL/Ka and athymic nude mice. After 3 months, the grafts maintained the histologic phenotype of the donor animal. Intercellular adhesion molecule-l continued to be expressed by basal keratinocytes of the cpdm/cpdm grafts after transplantation. In contrast, the basal keratinocytes of the C57BL/Ka grafts onto cpdm/cpdm mice remained negative for intercellular adhesion molecule-1 3 months after transplantation. An increased number of proliferating keratinocytes was present in the cpdm/cpdm skin-graft transplanted to nudes or to C57BL/Ka mice based on short-term bromodeoxyuridine labeling. The bromodeoxyuridine incorporation in the keratinocytes of the control C57BL/Ka skin grafts transplanted to cpdm/cpdm, nude, or C57BL/Ka mice was the same as in the keratinocytes of normal C57BL/Ka mice. This study demonstrates that the pathologic features found in the cpdm/cpdm mice are the result of a disorder in the epidermis or dermis and not due to a systemic defect.
