Increased N-Cadherin staining in irradiated tumours.

<p>The mesenchymal marker N-Cadherin (N-Cad) (A&B) and the epithelial marker cytokeratin (CK) (D&E) were analysed in all untreated and all 20Gy irradiated tumour sections. Quantitative assessment ([C] N-Cad, [F] CK) by Positive Pixel analysis of stained tissue sections. Staining was quantified as low, intermediate or high in the viable tumour area of untreated (black bars) vs irradiated tumours (grey bars). Red arrow indicates an example of a highly stained cell, yellow arrow indicates an area of low staining. Very low level background staining was discounted. ***p = <0.001 *p = <0.05.
