BMP4 and BMP7 expression in nevi, primary melanoma, and metastasis of malignant melanoma

Expression levelNevi (total = 11 sections)Primary melanoma (total = 5 sections)Metastasis of malignant melanoma (total = 4 sections)
  • NOTE: Immunohistochemistry analysis of nevi sections revealed no or only weak expression of BMP4 and BMP7. Primary melanomas showed strong expression for both proteins, whereas metastases of malignant melanoma showed moderate BMP4 expression and strong BMP7 expression.
