Skin equivalent: an attractive model to evaluate early melanoma metastasis.

The growth patterns and morphological phenotype of four human melanoma cell lines with different metastatic potentials were investigated in submerged and in air-exposed (skin equivalent) keratinocyte-melanoma cell co-cultures. In contrast to the submerged co-cultures, all four cell lines formed sharply demarcated tumour cell nests within the epidermal… (More)
