Of note, based on the microscopic analysis of mouse skin xenografts of SN-MM cells, we could identify a proliferation of MITFlow/CDH1−/CDH2+/ZEB1+/CD271+ melanoma cell clusters losing most melanocytic markers, thus suggesting a MIC identity, as proposed in CM [64, 90–92]. The gene discussed is CDH1; the disease is Miyoshi myopathy.
