Densitometric evaluation of SMA, laminin and fibronectin of 27 normal and 29 tumorous specimens of tissue microarray. In the tumors the average intensity of SMA immunostaining was 5.2-fold higher, laminin-1 protein expression showed a 3.8-fold increase and fibronectin reaction was similar, showing a non-significant 1.2-fold increase in cervical cancer tissues (black column) as compared with normal (gray column) tissues. The signal positivity is shown as a proportion of the total measured area. Stars indicate significance: ***p < 0.001.
