We investigated the distribution and formation of new lymphatic vessels in gliomas. Specimens from seven glioma cases were analyzed by immunohistochemical staining for CD34, lymphatic endothelial hyaluronic acid receptor 1 (LYVE‐1), prospero‐related homeobox 1 (Prox1), nestin, and hypoxia‐inducible factor 1α (HIF‐1α). Three types of vessels were observed in glioma specimens: LYVE‐1 + lymphatic vessels, CD34 + blood vessels, and LYVE‐1 + /CD34 + blood vessels. Prox1 + /LYVE‐1 + cells were distributed in some lymphatic vessels as well as among vascular endothelial cells and glioma cells. Nestin + cells were scattered throughout the gliomas, and some lymphatic cells also expressed nestin. HIF‐1α + Prox1 + cells were widely distributed within the glioma specimens. The present immunohistochemical analysis revealed upregulation of Prox1 and HIF‐1α in some glioma tissues as well as the differentiation of nestin + tumor stem cells into LYVE‐1 + lymphatic vessels.
