Randomized trial shows VPF improves endothelial regrowth in rabbits, suggesting a potential therapeutic approach.

This research aims to evaluate the effect of vascular permeability factor (VPF) on endothelial regeneration after angioplasty.
In vitro assessment of endothelial cell proliferation using 100 ng/ml VPF.
In vivo VPF administration (120 micrograms, twice weekly, i.v.) for 4 weeks following balloon angioplasty in rabbit carotid artery.
Comparative analysis of re-endothelialization between VPF-treated and control groups at 4 and 8 weeks post-treatment.
VPF treatment led to 57.5% endothelial regrowth at 4 weeks compared to 38.3% in the control group (P < 0.01).
At 8 weeks, VPF administration resulted in 88.1% re-endothelialization versus 44.7% in controls.

Callow et al. (1994) studied this question.
