Supplemental Table 1. Frequency of SFRP1 protein expression in 132 human tumour

subtypes. Normal and benign tissues are shown in bold and italic letters. In order to statistically analyse the loss of SFRP1 in malignant tumour tissues we selected entities derived from normal or benign tissues with high SFRP1-expression (moderate/strong >75%) and at least five analysed tissue samples (marked with an asterisk). AML: Acute myelogenous leukaemia. CNS: central nervous system. CML: chronic myelogenous leukaemia. GIST: gastrointestinal stromal tumour. MALT: mucosa-associated lymphoid tissue. NHL: non-Hodgkin’s lymphoma. PNET: primitive neuro-ectodermal tumour. TCC: transitional cell carcinoma.
