Scientists from Great Britain and Austria, using stem cells, have developed human blood vessels in laboratories.

“The capillary blood vessels look, smell, and taste like human blood vessels: Hence we call them blood vessel organoids. We then used these blood vessel organoids to model prototypic small blood vessel disease in diabetes. We were able to set up a diabetic milieu in a Petri dish that allowed us, for the first time, to model these diabetic blood vessel changes. Most importantly, we also grew a human vascular tree in experimental mice, (resulting in) a mouse with a perfect human blood circulatory system,”  Josef Penninger, director of the Life Sciences Institute at the University of British Columbia, told Digital Trends.

While the scientists say that being able to grow blood vessels will help in finding cures for diabetes and other diseases, there could be other applications too- for example, the blood could be used to quicken the pace of a wound healing.
