Abstract
The keratinocytes are able to migrate from the poly (2- hydroxyethylmethacrylate) disc if it is transfered to the new Petri-dish colonized with irradiated 3T3 mouse fibroblasts, and form a ring-shaped colony around the disc. The phenotypic characterization of human keratinocytes migrated from these discs was studied using a group of monoclonal antibodies. The keratinocytes in the external periphery of the colony of cells which migrated from the disc express the proliferating cell nuclear antigen (PCNA), α2, α3 chains and α5β1 integrin receptor. A protein of the desmosome complex, desmoplakin-1, was also expressed. Involucrin and cytokeratin-10 were expressed after prolonged cultivation. These results suggest that the migrated keratinocytes are able to proliferate, recognize extracellular matrix molecules important in the process of the re-epitelization of the wound, and terminally differentiate in vitro. They are encouraging for further experiments with respect to the development of a support for keratinocyte cultivation and for grafting in clinical practice.
