The effect of brain-derived neurotrophic factor on angiogenesis.

Abstract

To investigate the in vitro and in vivo proangiogenic effects of brain-derived neurotrophic factor (BDNF), human umbilical vein endothelial cells (HUVECs) were isolated and cultured in primary culture. The effect of BDNF on the proliferation of HUVECs was examined by MTT assay. The effects of BDNF on HUVEC migration and tube formation were studied by modified Boyden chamber assay and tube formation assay, respectively. Matrigel plug assay and chorioallantoic membrane assay were used to evaluate the effects of BDNF on angiogenesis in vivo. Our results showed that BDNF substantially stimulated the migration and tube formation of HUVECs in vitro, although it did not induce HUVEC proliferation. BDNF also induced angiogenesis both in matrigel plug of mouse model and in chick chorioallantoic membrane. In conclusion, BDNF can promote angiogenesis both in vitro and in vivo, and may be a proangiogenic factor.
