Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal neoplasm characterized
by a 'fortress' of thick collagen fibres, abundant myofibroblasts, and
paradoxically reduced vascularization compared to normal pancreas. Despite these
features, PDAC shows no reduction in the uptake of glucose that fuels tumour cell
survival. In new work published in The Journal of Pathology, Saiyin and
colleagues have identified a novel adaptation of PDAC tumour endothelium; namely,
'hairy-like' basal microvilli that increase the total vascular surface area and
correlate with regions of highest glucose uptake. Since basal microvilli are not
present on normal pancreatic blood vessels, their presence may add diagnostic
value and blocking their function is a potential new treatment strategy for PDAC.
This novel finding of basal microvilli on PDAC endothelium is a striking example
of how phenotypic plasticity in tumour blood vessels contributes to tumour growth
and progression, independent of conventional modes of angiogenesis.
