Studysummary Minoxidil treatment in mice preserved the integrity of elastic lamellae and improved arterial biomechanical properties, especially in females, suggesting it could be an anti-arterial aging agent potentially suitable for female-targeted therapies. Our plain-language summary of this paper — not a Tressless recommendation.
The study investigated the effects of chronic oral administration of minoxidil on the abdominal aorta structure and function in adult and aged male and female mice over 3 months. Minoxidil treatment preserved the integrity of elastic lamellae and stimulated the formation of new elastic fibers in aged mice. This resulted in decreased pulse pressure and improved arterial biomechanical properties, particularly in female mice, who showed increased aortic distensibility and decreased rigidity. The findings suggested that minoxidil could reverse some adverse effects of arterial aging and might be useful for female-targeted anti-arterial aging therapies.
