New insight has recently been obtained into the molecular mechanisms regula
ting the function of lymphatic endothelial cells. Vascular endothelial grow
th factors-C and -D have been shown to stimulate lymphangiogenesis. and the
ir receptor VEGFR-3 has been linked to human hereditary lymphoedema. althou
gh there is evidence that other genes are also involved. These data suggest
that it may become possible to stimulate lymphatic growth and function and
to treat tissue oedema involved in many diseases.
