Genetic ablation or overexpression of S100a4 in both Apc- and Smad4-mutant mice do not affect intestinal tumour initiation.
S100a4 overexpression in Apc1638N/+/KRASV12G mice increases the dissemination of intestinal tumour cells to the liver.
S100a4 deficiency results in a reduction of desmoids suggesting a novel role for S100a4 in desmoid formation.
S100a4 is co-expressed together with mesenchymal stem cell (MSC) markers in desmoid tumours.
