Materials and methods are provided to improve survival of lymph nodes and integration of lymph nodes into a lymphatic network, following lymph node transplantation. The treatment or prevention of lymphedema is also addressed. A method of lymph node transfer includes transferring or transplanting a lymph node or lymph node fragment in a mammalian subject; and administering a composition comprising an agent selected from the group consisting of Vascular Endothelial Growth Factor C (VEGF-C) polynucleotides, VEGF-C polypeptides, Vascular Endothelial Growth Factor D (VEGF-D) polynucleotides, and VEGF-D polypeptides to a perinodal site within 20 cm of the lymph node or lymph node fragment. In certain embodiments, the agent is present in the composition in an amount effective to promote survival of the lymph node and integration of the lymph node into a lymphatic network in the mammalian subject, at the site of transfer or transplantation.
