Scientists grow perfect human blood vessels in a petri dish

Date: 16.1.2019 

Scientists have managed to grow perfect human blood vessels as organoids in a petri dish for the first time. The breakthrough engineering technology, outlined in a new study published today in Nature, dramatically advances research of vascular diseases like diabetes, identifying a key pathway to potentially prevent changes to blood vessels - a major cause of death and morbidity among those with diabetes.

"Every single organ in our body is linked with the circulatory system. This could potentially allow researchers to unravel the causes and treatments for a variety of vascular diseases, from Alzheimer's disease, cardiovascular diseases, wound healing problems, stroke, cancer and, of course, diabetes."

Diabetes affects an estimated 420 million people worldwide. Many diabetic symptoms are the result of changes in blood vessels that result in impaired blood circulation and oxygen supply of tissues. Despite its prevalence, very little is known about the vascular changes arising from diabetes. This limitation has slowed the development of much-needed treatment.

To tackle this problem, Penninger and his colleagues developed a groundbreaking model: three-dimensional human blood vessel organoids grown in a petri dish. These so-called "vascular organoids" can be cultivated using stem cells in the lab, strikingly mimicking the structure and function of real human blood vessels.
