Vasculogenic mimicry
Vasculogenic mimicry is the formation of microvascular channels by aggressive, metastatic and genetically deregulated tumour cells.[1][2] This process differs from angiogenesis in that it occurs de novo without the presence of endothelial cells (tumour cells line tumour vessels effectively mimicking a true vascular endothelium). It was first described in uveal melanomas by Maniotis et al. in 1999.[3] There are two main types of vasculogenic mimicry: tubular and patterned. The former is morphologically similar to normal blood vessels, whereas the latter is visibly different although capable of undergoing anastomosis with blood vessels.[2]
The microvasculature generated through vasculogenic mimicry contains a basement membrane that stains positive with periodic acid–Schiff stain.[1]
History
After its discovery in 1999 a controversy arose in the field regarding the validity of the findings and conclusions of Maniotis and colleagues.[4] Nonetheless, their findings have been further supported by several research groups, becoming the focus of much interest due to its potential role as a therapeutic target and indicator of metastasis.[5]
