Demonstration that a simple three-amino-acid peptide could physically rebuild the microvascular network in aged organisms, restoring blood flow architecture to youthful levels.

Throughout the 1990s and into the early 2000s, Khavinson's research group conducted extensive preclinical studies to understand how the vascular peptide bioregulator (Ventfort/KED) actually works at the molecular level. Using cell culture systems with endothelial and smooth muscle cells derived from blood vessels, researchers discovered that Ventfort acts as what they termed a 'gene-switch'—a molecular signal that activates or normalizes the expression of genes critical for vascular health.

Preclinical research demonstrated several key mechanisms. First, Ventfort increased the expression of cell proliferation markers (particularly Ki-67) in aging vascular cells, essentially awakening their ability to repair and regenerate. Second, it simultaneously reduced expression of pro-aging markers like p53, which accumulates in senescent cells and drives cellular aging. Third, and perhaps most importantly, Ventfort normalized the expression of endothelial dysfunction markers. In atherosclerotic conditions, vascular endothelial cells become dysfunctional, overexpressing adhesion molecules like E-selectin that facilitate the binding of inflammatory cells to vessel walls and promote atherosclerotic plaque formation. Ventfort demonstrated the ability to suppress these pathological signals.

Animal model studies proved transformative. In aged rats, vascular peptide bioregulator treatment increased the density of microvascular networks by 2.5- to 2.8-fold compared to untreated aged controls—essentially reversing the vascular rarefaction (loss of small blood vessels) that occurs with normal aging. This wasn't just a biochemical effect on a petri dish; it was actual structural vascular regeneration visible under the microscope. Researchers also documented that Ventfort treatment improved cerebral blood flow in aging animals with hypertension, suggesting benefits for both peripheral and central nervous system circulation.
