Lymphangiogenesis in vitro: formation of lymphatic capillary-like channels from confluent monolayers of lymphatic endothelial cells.
Lymphatic endothelial cells grown long term in culture form lymphatic capillary-like tubes. Examination by light and transmission electron microscopy showed that these structures were closed loops composed of one to several cells connected by intercellular junction to form a luminal space. This first demonstration of lymphangiogenesis in confluent monolayer cultures of lymphatic endothelial cells (a) showed that collagen type I accelerated lymphatic capillary tube formation, whereas fibronectin and matrigel had no effect; b) provided a model to study lymphatic endothelial cell function and differentiation; and c) offered a possibility to distinguish differences between the process of lymphangiogenesis and angiogenesis by testing various factors and conditions that effect endothelial cell behavior.
