Abstract
Angiogenesis, activation of metastasis and avoidance of immune destruction are important for cancer progression. These biological capabilities are, apart from cancer cells, mediated by different cell types, including endothelial, haematopoietic progenitor and myeloid-derived suppressor cells. We show here that all these cell types frequently express the Wilms' tumour suppressor Wt1, which transcriptionally controls expression of Pecam-1 (CD31) and c-kit (CD117). Inducible conditional knockout of Wt1 in endothelial, haematopoietic and myeloid-derived suppressor cells is sufficient to cause regression of tumour vascularization and an enhanced immune response, leading to decreased metastasis, regression of established tumours and enhanced survival. Thus, Wt1 is an important regulator of cancer growth via modulation of tumour vascularization, immune response and metastasis formation.
