Vascular Endothelial Growth Factor Receptor, Flk-1,Localization in Purkinje Cell Processes

Vascular endothelial growth factor (VEGF) and VEGF receptors are implicated in angio- genesis or vasculogenesis in many tissues under both developmental and pathological conditions. Recent studies, however, have suggested that VEGF functions in non-vascular cells. To address whether VEGF receptor, Flk-1 or Flt-1, is expressed in the cerebellum under physiological conditions, we immunohistochemically examined the rat cerebellum at postnatal day 10 (P10), P15 and in adult- hood. Here, we demonstrate that rat Purkinje cells show Flk-1, but not Flt-1, expression in dendrites, cell bodies and axons at all stages examined. Its localization seemed to be in the cytoplasm or axo- plasm, and not restricted to the cell membrane. These data suggest that Flk-1 is constitutively expressed in rat cerebellar Purkinje cells, although its physiological function is totally unknown at present.
