In a study published in the journal Nature on Wednesday, researchers from the University of British Columbia detail how they were able to coax stem cells into growing into human blood vessel "organoids," the term used for three-dimensional, lab-grown cellular systems that mimic the characteristics of organs or tissues. They then placed the lab-grown blood vessels in a petri dish designed to mimic a "diabetic environment." They found that the basement membrane thickened in a way that was "strikingly similar" to the thickening seen in patients with diabetes, according to researcher Reiner Wimmer. The researchers then went on the hunt...
