Vasculogenic mimicry (VM) is a functional microcirculation pattern in malignant
tumors accompanied by endothelium-dependent vessels and mosaic vessels. VM has
been identified in more than 15 solid tumor types and is associated with poor
differentiation, late clinical stage and poor prognosis. Classic anti-angiogenic
agents do not target endothelium-dependent vessels and are not efficacious
against tumors exhibiting VM. Further insight into the molecular signaling that
triggers and promotes VM formation could improve anti-angiogenic therapeutics.
Recent studies have shown that cancer stem cells (CSCs) and
epithelium-to-endothelium transition (EET), a subtype of
epithelial-to-mesenchymal transition (EMT), accelerate VM formation by
stimulating tumor cell plasticity, remodeling the extracellular matrix (ECM) and
connecting VM channels with host blood vessels. VM channel-lining cells originate
from CSCs due to expression of EMT inducers such as Twist1, which promote EET and
ECM remodeling. Hypoxia and high interstitial fluid pressure in the tumor
microenvironment induce a specific type of cell death, linearly patterned
programmed cell necrosis (LPPCN), which spatially guides VM and
endothelium-dependent vessel networks. This review focuses on the roles of CSCs
and EET in VM, and on possible novel anti-angiogenic strategies against
alternative tumor vascularization.
