Figure 4From: Human periostin gene expression in normal tissues, tumors and melanoma: evidences for periostin production by both stromal and melanoma cellsCorrelation between POSTN expression and Breslow thickness of melanoma. POSTN and ACTB cDNA levels were measured in triplicate in primary tumors of melanoma with Breslow thickness <1.0 mm (n = 9), 1.01<>2.0 mm (n = 8), 2.01<>4.0 mm (n = 6) and >4.0 mm (n = 12) as described in Fig. 1 legend.Back to article page
