a Results of a ChemiArray Human Antibody Array (Millipore, Billerica, Massachusetts, USA) in which IL-6 was identified from the conditioned medium of NMFs or CAFs. The array was performed twice, data shown is representative of these runs. Black circles indicate controls, red circles identify IL-6 protein; b IL-6 is expressed approximately 100 fold higher in a CAF line (NR1) compared to NMFs (HuFb, B6 RA1H, F127H). QRT-PCR was performed in quadruplicate for each cell line in one experiment, error bars represent the standard deviation of the mean of quadruplicate data
